It is probable that Herbert fitz Herbert (I.) died during Stephen’s reign, and that Robert fitz Herbert, Herbert fitz Herbert, and Henry fitz Herbert,10 who appear soon after the Restoration, were his sons.
  10 HENRY FITZ HERBERT  was contemporary with Robert fitz Herbert and with Herbert fitz Herbert (II.). He is entered as paying two merks in the Wiltshire PipeRoll of 1158. In the Wiltshire and Gloucestershire Pipe-Rolls of 1159, this Henry accounts for a donum of five merks and owes 100 merks for some convention about lands. The last debt is probably the same with one of 100 merks, which is entered on the Worcestershire Pipe-Roll of 1160, as resulting from a Plea heard by William fitz John,—a Justiciar of that period. In 1161, a Scutage at the rate of two merks per fee was assessed on many Counties: Henry fitz Herbert paid five merks thereto in Wiltshire. This Henry was, I take it, the same person with that H. fitz Herbert who in 1165 acknowledges a tenure in capite of one knight’s-fee in Wiltshire (Liber Niger, I. 114). It is probable that he was a younger brother of Robert fitz Herbert and Herbert fits Herbert (II.).

This roughly translates as:
Charter of King Henry I reciting and confirming the grants of the donors.
  In the name of the Father, and of the Son, and of the Holy Spirit, amen, .... in all times of earthly power the greatest virtue was to support Christ's Church, so that by authority of kings and princes it may receive strength and increase, and the religion of God's flock may be augmented throughout the whole world. Indeed, it is the highest praise of royal dignity when many tokens of uprightness concerning faith and religion are tasted for the memory of posterity. Therefore I, Henry, by the grace of God king of the English and duke of the Normans, desiring always to have Christ's poor as advocates in the heavenly court, inasmuch as they are its citizens and prelates, flee to them as to a refuge of holy protection, that by their help I may deserve salvation, who deem myself worthy of nothing by my own merits. Wherefore, by the authority of royal power, I confirm the church of the blessed Oswald, king and martyr, which is situated near the castle of Pontefract, in the place called Nostell, above the fishpond, and in which regular canons have been established to serve the living God by the hand of the venerable Thurstan, Archbishop of York.
  And the grant which I make to the church of the foresaid martyr and to the canons of that place is this: namely, I grant to them forever, free and quit, the whole wood that is around the same church, called Saint Oswald's Wood, as fully and honorably as Ilbert de Lacy or his son Robert ever held it. I also grant them forever in royal gift twelve pence a day from my own farm of Yorkshire. Likewise half a carucate of land in which the foresaid church is situated and which adjoins the church, and two bovates of land in Hardwick, which land Robert de Lacy gave and granted to them, and Ralph Grammaticus, so far as pertained to him, I grant to them free, quit, and discharge from all earthly service and royal customs in perpetuity by royal munificence. Furthermore, I confirm the gift which I made to the foresaid church and its canons: namely, the churches of St. Oswald and St. Aidan of Bamburgh, as fully as Algar the priest ever held them; and the church of the castle of Tickhill, which they have by gift of Archbishop Thurstan (who previously possessed it by my gift), with lands, tithes, and all things belonging to the foresaid churches.
  I also confirm by royal power the donations which the magnates and nobles of my realm have made to the foresaid canons: namely,
… From Herbert fitz Herbert, and Williama his brother, treasurer of York, the church of Weaverthorpe, with all appurtenances belonging to it, with the consent of Archbishop Thurstan;

The charter above is also printed in Rotuli Chartarum in Turri Londinensi Asservati 1199-1216 vol 1 p215b (1837)

In 1129 or 1130, Herbert paid an enormous sum for this time (353 marks) to inherit his father's lands. This indicates the huge wealth of the elder Herbert, and also fixes an approximate date for his father's death. The Pipe Roll of 31 Henry I covers the previous financial year (Michaelmas to Michaelmas, i.e. 29 September 1129 to 29 September 1130).

This entry in the Red Book of the Exchequer documents Herbert as the son of Herbert the Chamberlain. The entry concerns two knights fees held in Southamptonshire. The entry implies that Herbert had already died by this date since his son held the lands.

  HERBERT FITZ HERBERT, the husband of Sibil, or, as she is sometimes called, Adela Corbet. Herbert fitz Herbert, with William, Treasurer of York, his brother, and by consent of Turstin, Archbishop of York, granted the Church of Wivertorp to the Yorkshire Priory of Nostel.8 There can be no doubt that this grant was made, but if the Confirmation of Henry I., which embodies it, be a genuine document, and accurately transcribed, the grant must have taken place previous to the year 1127, when Richard, Bishop of Hereford (one of the ostended witnesses of the Confirmation) died. I know of nothing to back the idea thus suggested, that Herbert fitz Herbert and his brother William were in a condition to grant so early. Herbert fitz Herbert had a suit with Herbert, Abbot of Westminster, about lands at Pereham and Maseleford in Sussex. The Suit was settled by judgment of the Barons of the Exchequer in favour of the Abbot, and a Writ of King Henry I. certified the result to the Sheriffs of Sussex and Middlesex.9
  We have seen Herbert fitz Herbert liquidating his Fine on succession in 1130. Of his conduct in the civil wars between Stephen and the Empress I can learn nothing, but as one of his sons married Lucia, a daughter of Milo, Earl of Hereford, we may presume that this branch of the Fitz Herberts took the side of legitimacy. It is probable that Herbert fitz Herbert (I.) died during Stephen's reign, and that Robert fitz Herbert, Herbert fitz Herbert, and Henry fitz Herbert, who appear soon after the Restoration, were his sons.

  And the lord king gave to Hugh de Lacy, as was said above, all Meath in Ireland with its appurtenances for the service of 100 knights, to be held from himself and John his son, and he made his charter to him thereof. And he gave there to Robert fitz Stephen and Miles de Cogan the kingdom of Cork, for the service of 60 knights, to be held from himself and John his son, except the city of Cork with one cantred, which the lord king retained for himself and his heirs. And he gave there to Herbert fitz Herbert, and William, brother of earl Reginald2, and Goscelin de la Pomerai their nephew, the kingdom of Limerick, for the service of 60 knights, to be held from himself and John his son; except the city of Limerick with one cantred [unit of land equivalent to a hundred], which the lord king retained for himself and his heirs.
…  Then3 the lord king came to Marlborough, where the king gave to Philip de Braose the whole kingdom of Limerick for the service of sixty knights, to be held from himself and from John his son. For Herbert and William, brothers of Reginald, earl of Cornwall, and Goscelin de la Pomerai their nephew, were unwilling to have that kingdom, because it was not yet conquered. For after king Monoculo4 [the One-Eyed], who was king of Limerick and had been the king of England's man for it, was slain by the king's men, a certain man of his lineage, a powerful and strong man, invaded, seized, and powerfully ruled the kingdom of Limerick, rendering no subjection to the king of England; nor was he willing to obey his [the king's] men because of their faithlessness and the undeserved evils they were inflicting upon the people of Ireland. Indeed, the king of Cork and many other rich men of Ireland rose up against the king of England and his men: and their last state was worse than the first, and they slaughtered one another.

  Yorkshire.— Let those present and future know that it has been thus agreed between Herbert, son of Herbert, and Peter, his son, concerning the marriage of Alice, daughter of Robert, son of Roger, whom the same Peter has taken as his wife: that the aforesaid Herbert has given and granted to Peter, his son, for the dower of the aforesaid Alice, his wife, his entire tenement [estate/holding] of Yorkshire, of which he seized [legally put him in possession of] him in the presence of the Lord H[ubert], archbishop of Canterbury, G[eoffrey] fitz Peter, justiciar of the lord king, William de Cantilupe, Reginald de Cornhill, Richard de Seinghes, and many others; and the same Peter has endowed his aforesaid wife Alice therewith, with the assent of his father. The same Peter has also granted to his father the entire aforesaid tenement, both on behalf of himself and of Alice his wife, to be held at farm [leased] for the entire life of the same Herbert for one hundred marks annually, to be paid at two terms of the year: namely, fifty marks at Easter and fifty marks at the Feast of Saint Michael [Michaelmas]. So that if the aforesaid Herbert does not pay that farm to the late Peter or to the aforesaid Alice his wife at the appointed terms, Peter himself and Alice his wife shall receive that entire tenement into their own hand without any objection from the aforesaid Herbert. And if Peter or Alice his wife does not abide by this agreement, the aforesaid Herbert shall be quit [released] from paying the aforesaid farm to them. If, however, it happens that the aforesaid Peter dies before his father, Herbert himself shall pay that farm in its entirety to the aforesaid Alice, wife of the aforesaid Peter, during her life; so that if the aforesaid Herbert does not pay that farm to the same Alice at the appointed terms, Alice herself shall receive that entire tenement into her own hand without any objection from the same Herbert. And if Alice herself acts contrary to this agreement in any way, the aforesaid Herbert shall be quit from paying the aforesaid farm to her. And the same Alice, after the death of the aforesaid Herbert, if she survives him, shall recover that entire tenement as her dower. For the firm holding of this agreement on both sides, the pledges are the aforesaid lord archbishop of Canterbury and G[eoffrey] fitz Peter, justiciar. And if the aforesaid Herbert should wish to withdraw from that agreement in any respect, the aforesaid lord archbishop, with the assent of Herbert himself, shall distrain him through ecclesiastical justice according to the agreement… and the charter made between them… and so the said Herbert shall make his charter to the preferred Peter, his son, according to that writing; Peter also shall make his charter to Herbert, his father, according to the same writing; and the said Herbert shall make his charter thereof to the wife of the same Peter, and the same wife to the aforesaid Herbert. This agreement was recorded at Westminster and granted on the 20th day of November in the fifth year of the reign of king John [20 November, 1203], before Richard de Herriard, Simon de Pattishall, Godfrey de l'Isle, John de Gestinghes, Osbert fitz Hervey, Eustace de Fauconberg, Walter de Crepping, justices, and other faithful subjects of the lord king then present there.

This confirmation by the king of a gift Herbert made to the church is dated 20 April 1204, but it is not clear whether Herbert had already died at this date (a different charter confirms his death by 18 July 1204)

  HERBERT FITZ-HERBERT, who obtained from HENRY II. a confirmation of the landed possessions of his father, and likewise the office of chamberlain. In the 12th of that monarch, anno 1166, upon the assessment of the aid which was then levied for marrying the king’s daughter, he certified that he held one knight’s fee in Wilts and three in Berks. Upon the Conquest of Ireland HENRY II. at a great council held at Oxford anno 1177 gave the kingdom of Limeric in that Realme to this Herbert and William his brother, Reginald, Earl of Cornwall and Josceline de la Pomerai their nephew (the City of Limeric and one cantred excepted, which the king reserved to himself and his heirs) to be held by the service of sixty knight’s fees, but it appears they declined the gift. In the 6th of RICHARD I. he was sheriff of the county of Gloucester, for one of that year and afterwards during the whole reign of that king. In the eighth of the same reign he was likewise sheriff of Shropshire. He m. Lucie, third dau. and co-heir of Milo Fitzwalter, Earl of Hereford, and by her acquired the Forest of Dene, where he afterwards resided in the Castle of St. Michael, with other large possessions in the counties of Brecknock and Gloucester.

This roughly translates as:
Lucy was married to Herbert fitz Herbert with all the forest of Dene and other lands. But this Herbert, on account of a trespass which he had committed against the king of England, Henry the Second, son of the empress, in the fourth year of that king, surrendered and quitclaimed all the forest.

    Woodcote.
  HERBERT FITZ HERBERT (II.). In 1156, I find Herbert fitz Herbert excused his quota of scutage, as a military Tenant under the Abbeys of Hide and Abingdon.
  A Monastic Stemma assures us that Herbert fitz Herbert, having (as his wife Lucia’s share of the Earldom of Hereford) the Forest of Dene and other lands, quitclaimed the said Forest to Henry II. for some political offence against that monarch.13 This surrender the Chronicler dates in the fourth year of Henry II., that is, in the year 1158, when we know from better authority that Earl Milo’s male issue was not extinct, and that therefore the coheirship of his daughters could not have arisen. In the year 1165, Earl Milo’s sons were all dead, and Margaret de Bohun, the eldest of his daughters, duly appears with her share of Earl Milo’s estates.14 The Record however bespeaks no similar recognition of the claims of Herbert fitz Herbert. His only tenure-in-capite was four knights’-fees, entered under Berkshire, on which he owed the Serjeantry or Service of his own person; that is, the discharge of his duties as a Royal Chamberlain.15 Herbert fitz Herbert also held two knights’-fees under the Bishop of Winchester, three knights’-fees under the Archbishop of York, one knight’s-fee under the Abbot of Abingdon, one knight’s-fee under John de Port of Hampshire, and half a fee under the Earl of Gloucester. All these were apparently of the old feoffment, and therefore inherited from his ancestors. The Bishop of Winchester’s statement of Fitz Herbert’s tenure proves his descent as I have drawn it. It is as follows—“Herbert, son of Herbert the older Chamberlain, held a fee of two knights (in the time of King Henry I.): and now Herbert his son holds it.”16 The succession of three generations of Herberts, and when they lived, is as clear as Record can make it.
  It is now time to advert to various marks of disfavour discernible in the dealings of Henry II. with Herbert fitz Herbert (II.). It is evident that he was admitted to far less than a full share of the inheritances which should have come to him by his wife and his mother; and there is some proof that at one period he was under total forfeiture. The cause of all this is merely matter of conjecture, but what I have to offer will at least bear the test of chronology. It is probable that Robert fitz Corbet’s legitimate coheirs were not allowed to enter on his Barony during the lifetime of his illegitimate Grandson, Reginald, Earl of Cornwall. Of Alcester, at least, it is certain that Earl Reginald held the whole Manor for his life, and that it remained an Escheat long after his death, which happened in December 1175.17 Herbert fitz Herbert, the Earl’s half brother, was not as yet in disfavour with Henry II., if we may judge firom the following fact. Early in May 1177, the King held a Council at Oxford about Ireland, and there granted the Kingdom of Limerick to “Herbert fitz Herbert, to William, brother of Earl Reginald, and to Joel de la Pumerai, their Nephew (nepoti eorum).18 At another Council, at Marlborough, about a fortnight after, Herbert and William, brothers of Reginald, Earl of Cornwall, and Joel de Pumerai, their nephew, declined receiving the said Kingdom;19 and King Henry forthwith granted it to Philip de Braose.20
  The Herefordshire Pipe-Roll of 1185, gives us ample evidence that previous to Michaelmas 1184, Herbert fitz Herbert had incurred summary forfeiture. Geoffey fitz Piers had custody of his Manors. He accounts £20. 0s. 10d. for the old ferm thereof, that is, he hands over to the Exchequer that amount, received previous to Michaelmas 1184. The current year’s receipts amounted to £121. 19s. 2d.; a noble income in those days. Out of these receipts the Justiciar had disbursed £5. in the maintenance and hire of seven of his own servants, who had been set (assisi) to keep the said land. He had also, by the King’s order, bestowed £4. 10s. 8d. in the livery of Herbert fitz Herbert himself; whose personal liberty seems, on this evidence, to have been abridged. Before King Richard had reigned a year, we know that Herbert fitz Herbert recovered his part of his wife’s inheritance. The Wiltshire Pipe-Roll of 1190 records his payment of £33. 3s. 10d., or nearly half of a Fine of 100 merks, which he had negotiated for his said share. It is probable that, during the reign of Richard I., Herbert fitz Herbert (II.) was also restored to his moiety of Alcester, and to such a share of Robert Corbet’s Barony as is afterwards found in his Successors. A meagre share indeed it was; for of five Domesday Manors already reviewed in these pages as members of Robert Corbet’s Fief, Herbert fitz Herbert appears to have had an interest, and that temporary, in only one, viz., Ratlinghope. Woodcote, now under notice, is the first that I can trace to his descendants. The Knight’s-service which the Fitz Herberts owed to the Crown for their Shropshire Fief, was merely that of half a fee. The first and only Shropshire Scutage to which Herbert fitz Herbert was assessed, was the 4th Scutage of John, levied in 1203. He was charged one merk for half a knight’s-fee, and paid it. Before June 1204 he had been succeeded by his son and heir, Peter fitz Herbert, of whom we have already had mention as associated with the Wiltshire Law Suits of his Father in the previous reign.21

He did homage and had livery of the lands of which his mother, Joan, had divested herself, 21 Feb. 1230/1 (Fine Roll, 15 Hen.

This Joan (who was married to Matthew before June 1200) was da. and h. of Mabel Patric (Curia Regis, roll no. 16, m. 21), and eventually heir (and probably niece) of William de Mandeville. In 9 Ric.

III, m. 13).

Children: Occupation: Baron

Matthew was one of the barons to king John who signed the Magna Carta. He was also sheriff of Sussex (appointed 1215, still documented in 1223) and a royal judge (1227)

Notes:
Matthew was a prominent Anglo-Norman baron, military commander, and administrator whose career bridged the reigns of king John and Henry III. Serving as Sheriff of Sussex and keeper of key coastal fortresses like Pevensey and Chichester during the First Barons' War, Matthew remained a steadfast royalist during the First Barons' War of 1215–1217. In August 1216, as royal authority wavered, king John rewarded his loyalty with confiscated rebel lands in Gloucestershire. Following the death of king John, Matthew transitioned seamlessly into the service of the Regency Council under William Marshal and Hubert de Burgh, maintaining his shrieval authority in Sussex and helping stabilize the southern coastline following the Treaty of Kingston in September 1217. In the post-war era, Matthew’s role evolved from frontline military governance to high-level judicial and administrative service. In late 1217 and 1218, he headed local commissions to restore order and prosecute crimes committed during the war, and by November 1218 he was appointed a senior Justice in Eyre for the southern circuit covering Wiltshire, Hampshire, Berkshire, and Oxfordshire. Beyond his judicial duties, Matthew actively participated in council politics, acting alongside his brother Peter fitz Herbert as a mainpernor for the release of the hostages of the House of Braose, and served as a naval commissioner. During the crisis of 1224 Matthew was dispatched to mobilize warships and supply craft to defend Guernsey and the Channel Islands.

A brachetum was a scent-hound used in royal hunting. King John was notorious for impounding or confiscating favored animals, falcons, or land from his courtiers and exacting whimsical or edible fines to return them. That Matthew would offer 100 capons specifically to recover a single hunting dog underscores both the high personal value placed on trained hunting hounds among Anglo-Norman magnates and Matthew's direct access to King John's immediate entourage.

  Matthew son of Herbert gives one hundred capons, to be rendered within the beginning of Lent, so that the lord King may return to him his scent-hound.

This roughly translates as:
54.  Robert fitz Brian, Oliver Avenel, Geoffrey Talbot, and Adam de Dornapeton, four knights of Southamptonshire, sent to Reginald de Albemarle, who had excused himself on grounds of bed-sickness against Matthew fitz Herbert and Joan his wife concerning a land plea, wherein Matthew and Joan claim that Reginald defaulted because he failed to appear on the day appointed by those knights, come and say that Adam and Robert visited Reginald on the Wednesday next before the Feast of the Nativity of St. John the Baptist [19 June 1219] and appointed him a day [to appear], namely fifteen days from Thursday [4 July 1219] at Westminster; and the other two knights visited him on that same Thursday and appointed him the same day. When asked what warrant they had for this, they say the sheriff instructed them, but they had no writ, nor had the sheriff specified any particular day; therefore, they [the four knights] are at mercy.
  And Reginald says regarding this that it seems to him Matthew made default, because the knights appointed him a day on which he himself appeared, whereas Matthew neither appeared nor excused himself, and he asks that this be allowed in his favor.

  Yorkshire.— Let those present and future know that it has been thus agreed between Herbert, son of Herbert, and Peter, his son, concerning the marriage of Alice, daughter of Robert, son of Roger, whom the same Peter has taken as his wife: that the aforesaid Herbert has given and granted to Peter, his son, for the dower of the aforesaid Alice, his wife, his entire tenement [estate/holding] of Yorkshire, of which he seized [legally put him in possession of] him in the presence of the Lord H[ubert], archbishop of Canterbury, G[eoffrey] fitz Peter, justiciar of the lord king, William de Cantilupe, Reginald de Cornhill, Richard de Seinghes, and many others; and the same Peter has endowed his aforesaid wife Alice therewith, with the assent of his father. The same Peter has also granted to his father the entire aforesaid tenement, both on behalf of himself and of Alice his wife, to be held at farm [leased] for the entire life of the same Herbert for one hundred marks annually, to be paid at two terms of the year: namely, fifty marks at Easter and fifty marks at the Feast of Saint Michael [Michaelmas]. So that if the aforesaid Herbert does not pay that farm to the late Peter or to the aforesaid Alice his wife at the appointed terms, Peter himself and Alice his wife shall receive that entire tenement into their own hand without any objection from the aforesaid Herbert. And if Peter or Alice his wife does not abide by this agreement, the aforesaid Herbert shall be quit [released] from paying the aforesaid farm to them. If, however, it happens that the aforesaid Peter dies before his father, Herbert himself shall pay that farm in its entirety to the aforesaid Alice, wife of the aforesaid Peter, during her life; so that if the aforesaid Herbert does not pay that farm to the same Alice at the appointed terms, Alice herself shall receive that entire tenement into her own hand without any objection from the same Herbert. And if Alice herself acts contrary to this agreement in any way, the aforesaid Herbert shall be quit from paying the aforesaid farm to her. And the same Alice, after the death of the aforesaid Herbert, if she survives him, shall recover that entire tenement as her dower. For the firm holding of this agreement on both sides, the pledges are the aforesaid lord archbishop of Canterbury and G[eoffrey] fitz Peter, justiciar. And if the aforesaid Herbert should wish to withdraw from that agreement in any respect, the aforesaid lord archbishop, with the assent of Herbert himself, shall distrain him through ecclesiastical justice according to the agreement… and the charter made between them… and so the said Herbert shall make his charter to the preferred Peter, his son, according to that writing; Peter also shall make his charter to Herbert, his father, according to the same writing; and the said Herbert shall make his charter thereof to the wife of the same Peter, and the same wife to the aforesaid Herbert. This agreement was recorded at Westminster and granted on the 20th day of November in the fifth year of the reign of king John [20 November, 1203], before Richard de Herriard, Simon de Pattishall, Godfrey de l'Isle, John de Gestinghes, Osbert fitz Hervey, Eustace de Fauconberg, Walter de Crepping, justices, and other faithful subjects of the lord king then present there.

Alice was da. of Robert fitz Roger, of Warkworth ( Pipe Roll, 5 Joh., m. 5; Close Roll, 19 Hen. III, m. 11 ) (The Complete Peerage vol 5 p465n (George Edward Cokayne, 1926)). See Medieval Lands (PIERS FitzHerbert) "ALICE, daughter of ROBERT FitzRoger of Warkworth & his wife Margery de Chesney. "

Children: Married (2nd): Isabel (de Ferrers) de Mortimer

Isabel was the daughter of Walkelin de Ferrers. She married, firstly, Roger Mortimer of Wigmore, with whom she had five children - Hugh, Ralph, Robert, Philip and Joan. Roger died in 1214. Isabel outlived Peter by many years, dying shortly before April 29, 1252, when her manor at Lechlade was ordered to be taken into the king's hands. She lived her final years as a nun and patroness of the St. John the Baptist Hospital at Lechlade, Gloucestershire, where she was buried.

Isabel is named as the wife of Peter and brother of Henry de Ferrers in an entry in the Fine Rolls in 1225.

Occupation: Baron of Berstaple in Devonshire; Governor of Pickering Castle and Sheriff of Yorkshire

Notes:
Peter FitzHerbert was a powerful 13th-century nobleman, courtier, and Marcher Lord. He was a prominent royal advisor to king John and as one of the barons named in the preamble of the Magna Carta in 1215. Through his mother, Peter inherited a lucrative one-third share of the barony of the Earl of Hereford including Blaenllynfi and Castell Dinas. He held extensive lands spanning Berkshire, Oxfordshire, Warwickshire, Wiltshire, Yorkshire, and the Welsh Marches.
  Peter was closely allied to king John. The king rewarded his loyalty by granting him the honour of Barnstaple in Devonshire and appointing him governor of Pickering Castle and sheriff of Yorkshire (1214–1215). Because he stayed loyal to the crown during the Papal Interdict (1208–1213), medieval chroniclers like Roger of Wendover branded him one of king John's "wicked councillors". Peter was chosen as one of the noble councillors listed in the opening of the Magna Carta in 1215 to advise the king. He rebelled against king John toward the end of the First Barons' War, resulting in the temporary seizure of some of his lands. However, he quickly returned to royal allegiance upon the accession of the young king Henry III in 1216, and his estates were restored. In October 1233, during the rebellion of Richard Marshal, 3rd Earl of Pembroke, Peter's Welsh strongholds of Blaenllynfi and Castell Dinas were sacked and ruined by Marshal and prince Llywelyn ab Iorwerth.

Peter is recorded in 1194-5, paying scutage of 15 shillings for three quarters of a knight's fee in Berkshire.

Peter inherited a moiety of the manor of Alcester, Warwickshire, from his father and, after payment of 20 marks to the king, this was restored to him in 1204.

Peter was named by Roger of Wendover as one of king John's "wicked councillors" for assisting the king in his expropriation of church property following John's excommunication by pope Innocent III in a dispute over who was to be named archbishop of Canterbury.

  Moreover, during this storm of the interdict, the king had most wicked councillors, whose names I will not omit to set down here in part; William, the king's brother and Earl of Salisbury, Alberic de Vere, Earl of Oxford, Geoffrey son of Peter, justiciar of England, … Peter son of Herbert and Thomas Basset, and many others, whom it would be tedious to enumerate, who, desiring to please the king in all things, gave advice not according to reason but according to their will.

In 1212 Peter was one of a number of powerful nobles who stood surety for Peter de Maulay, another of the "wicked councillors" in his reconciliation with king John.

Cause the meat to be salted, and let the heads of the boars be soused in wine for our use, and cause the other cut meat prepared in ale to be safely guarded. Witnessed as above [the king at Rayleigh, the 8th day of November].

This entry from the Close Rolls documents Peter operating as the supreme royal official in the North of England: sheriff of Yorkshire and keeper of three massive royal castles. The king issues a direct mandate to the the barons of the exchequer ordering them to credit Peter's account for the heavy operational expenses he incurred maintaining these fortresses, offsetting his balance against the revenues he collected from the county.

This entry from the Close Rolls, dated April 13, 1215, shows king John scrambling to manage his aristocratic relationships just two months before the signing of Magna Carta. The king orders Peter to immediately refund £27 that Peter had previously confiscated from the northern estates of the powerful baron William de Forz, earl of Aumale, while those lands were temporarily seized into the king's hands. Because the earl of Aumale held the massive northern lordship of Holderness in Yorkshire, it was Peter, operating as the regional sheriff and custodian, who physically marched onto the earl's manors, seized his agricultural revenues, and collected this £27 on behalf of the royal treasury. In the spring of 1215, king John’s regime was on the verge of total collapse as the baronial rebellion intensified. William de Forz, earl of Aumale, was a highly volatile, heavily armed military heavyweight whose allegiance was critical. To keep Aumale from joining the rebel camp, the king suddenly reversed his previous asset seizures and ordered Peter to swiftly hand back the confiscated cash.

This entry from the Close Rolls, dated 1 June 1215, is at the precipice of the Magna Carta crisis, a mere two weeks before king John marched to Runnymede to meet the rebel barons who had already occupied London and renounced their feudal allegiance to the king. Trapped at Windsor Castle, the king was frantically deploying his remaining patronage to guarantee the loyalty of his inner-circle court. Handing Peter "full seisin" of Wolverton "without delay" was an urgent reward designed to ensure Peter remained a loyal frontline crown commander as the realm fractured.

These Close Roll entries from November 1215 and April and May 1216 are during the First Barons' War. Having captured Rochester Castle after a brutal siege, the king redistributed the lands, properties, and livestock of his rebel enemies to reward his staunchest royalist commanders, showering Peter with confiscated estates and knight's fees in Hampshire, Berkshire, Oxfordshire, Somerset and Southampton.

Interestingly, William and Peter's daughter, Lucy FitzPiers, were married (was this before or after 1216?).

Prince Louis of France invaded England with a massive army and took control of London. Seeing king John cornered, a huge wave of his core counselors (including the king's own half-brother, William Longespée, earl of Salisbury) realized the royal cause was doomed and defected to the French-baronial alliance. Peter, who had been firmly loyal to king John though the Magna Carta and siege of Winchester followed them into the rebel camp. In response, a furious king John retaliated, stripping the "traitor" Peter of his midland ancestral lands at Alcester and turning them over to the loyalist captain William de Camville.

As a further consequence of Peter's rebellion, all his lands were temporarily ("as long as it shall please us") confiscated in March 1217 by the regent of the young Henry III in favour of the king's half-brother, Oliver. In April the regent, Earl Marshal, offered Peter a truce encouraging him to abandon the rebellion and Peter returned to crown allegiance before the decisive Battle of Lincoln against prince Louis.

This entry refers to the Hospital of St. John the Baptist at Lechlade, which Peter formally founded in the 1220s, next to the primary bridge over the River Thames. In the 13th century, a "hospital" was an ecclesiastical almshouse and chapel complex run by an Augustinian prior and monks, built to offer free shelter, medical care, and food to poor travelers, pilgrims, and local infirm unfortunates. Because Peter had built the bridge and its raised earthen approach causeway, he wanted to erect a formal gate structure directly in front of his new hospital. The king approves the project on the condition that the gate must remain permanently open and clear to everyday commercial traffic, ensuring that pedestrians, mounted knights, and heavy trade wagons can cross the Thames freely without extortion or obstruction.

  PETER FITZ-HERBERT, Baron of Berstaple in Devonshire, the honor of which he obtained from King John, with fifteen knight’s fees, part of the lands of William de Braose, and he was made Governor of Pickering Castle in Yorkshire, and Sheriff of that county by the same moarch. This Peter was one of the barons named in Magna Charta, and by his signature fourth in rank amongst the barons. He m. first, Alice, dau. of Robert Fitz Roger, a great baron in Northumberland, Lord of Warkworth and Clavering, and sister of John, to whom EDWARD I. gave the surname of CLAVERING, Lord of Callaly in Northumberland. By this lady he had a son and heir, REGINALD FITZ PETER. He m. secondly Isabel, dau. and coheir of William de Braose, and widow of David Llewellin, Prince of Wales, and by the alliance acquired the lordships and castles of Blenlevenny and Talgarth in the county of Brecknock, with other possessions in Wales. He fortified his castle of Blenlevenny, and dying in 1235 was s. by his son,

  PETER FITZ HERBERT, about June 1204, gave King John 20 merks “to have seizin of that moiety of the Manor of Alenc̃ (Alcester) which his Father had held.”24 It would seem that the Father’s tenure at Alcester had been somewhat qualified, for King John, by a Writ of July 18, 1204, orders that a permanent equivalent for his land of Alcester be provided for Hamo Falconer, who, it seems, was ejected by force of the restoration made by the King to Peter fitz Herbert.25
  For the general career of Peter fitz Herbert, I may safely refer to the usual authorities. His connection with Shropshire too, slender as it was, will be, or has been, marked under the localities concerned. His Scutages in that County, with one or two other matters, I will give here.—
  Of the fifth, sixth, and seventh Scutages of King John, assessed in 1204, 1205, and 1206, he had special quittance in Shropshire. The Shropshire Feodary of 1211 has this entry.—“Peter fitz Herbert, Baron, holds in capite of the King, and owes the service of half a knight.”26 For the Scutage of Poitou, in 1214, he had quittance, but his liability is stated as that of a whole fee. In 1218 he paid one merk on half a fee to the first scutage of Henry III. In 1221 and 1224 he had quittance of the scutages of Biham, Montgomery, and Bedford. To the scutage of Keri in 1229, he was assessed on a whole fee, but afterwards excused. In 1230 he was assessed on one fee to the Scutage of Brittany, but was excused. In 1231 he was assessed, at the current rate of 3 merks, to the Scutage of Poitou. He was excused the assessment on one fee for the scutage of Elvein in 1232.
  Peter fitz Herbert is stated by difierent authorities to have been married at least three times. His first wife, I take it, was Alice, daughter of Robert fitz Roger, whom Dugdale calls “a great Baron of Northumberland.”27 This match took place in 1203; for, in Michaelmas Term of that year, Herbert fitz Herbert conceded all his Yorkshire lands to his son Peter, to the end that the latter might provide a dower for his aforesaid wife.28
  Another wife of Peter fitz Herbert is said to have been the third daughter and coheir of that William de Braose who was hanged by Lewellyn in 1229-30.29 This Lady is stated to have brought to her husband the land of Blayntheleveny and of Thalegard;—estates which certainly were held by subsequent Fitz Herberts. However, about this match there is some confusion and doubt. A Writ of October 30, 1234, speaks indifferently of all the coheirs of William de Braose as infants in ward to the Crown;30 and we know too that Peter Fitz Herbert, having married Isabel de Ferrars in or before 1225, left her surviving at his own decease in 1235.31 These considerations seem to leave no room for such a second and intermediate wife of Peter fitz Herbert as the alleged daughter of Braose.32 According to Dugdale, Blayntheleveny and Thalegard descended to Peter fitz Herbert from his father, and did not accrue by any marriage of his own.

  32 There is other mention of a fourth daughter of William de Braose and Eve Marshall, besides the three who undoubtedly married Mortimer, Cantilupe, and Bohun. A Monastic Stemma (Monasticon, VI. 134) calls the said Lady, Isabel, and gives her as the wife of David ap Lewellyn, Prince of Wales. Chronology does not contradict, nor does the Welsh Chronicle support, this. David ap Lewellyn died issueless in 1246.
  If this story be true, it bears curiously on another, already sifted and questioned (Vol. IV. p. 216, note 84). The two combined would prove that Isabel de Braose, in marrying David, married the son of the man who hanged her Father!

Although the death of Peter is stated in Annales de Theokesberi to be 1 July, it is likely that this is an error for 1 June ("Kal. Junii" rather tham "Kal. Julii") as Peter is documented to have already died in a document related to his estate dated 6 June 1235.

  ROBERT FITZ HERBERT  succeeded to the Office and estate of his father, ere Henry II. had been three months on the throne of England. This is proved by a Charter of the said King, which, by its testing-clause, combined with the place of its date (Lincoln), may be shown to have passed in February or March 1155. The substantive part of this Charter is as follows.—Henricus Rex Anglie, etc. etc. Sciatis me reddidisse Roberto filio Hereberti Camerarii, totam terram patris sui et Ministerum patris sui de Camerariâ meâ. Quare volo, etc. etc., sicut pater suus vel avus suus liberius tenuerunt tempore Regis Henrici avi met vel aliorum antecessorum meorum. Testibus,—Philippo Episcopo Baiocensi; Ernulfo Episcopo Lexoviensi; Toma Cancellario; Rainaldo Comite Cornubie; Ricardo de Humez, Constabulario; Johanne Marescallo. Apud Lincolliam.11
  The notable points in this Charter are,—first, that the King’s act was in the nature of a restoration, expressed by the word reddidisse; secondly, that Robert is proved to have been the third lineal Chamberlain of his family; lastly, that Reginald, Earl of Cornwall, is appropriately made a witness, where the Grantee was his own uterine brother.
  In 1161, 1 find Robert fitz Herbert assessed at five merks to a Scutage in Wiltshire. There is something remarkable in the low position which Robert fitz Herbert occupies in the testing-clause of a Haughmond Charter which seems to have passed about this time.12 Of his attendance at the Court of Henry II. I cannot cite a single instance. This, considering his official position, is not without its meaning. The younger brothers of Robert fitz Herbert seem, even in his lifetime, to have been more important personages than himself. I venture to suggest that some cloud obscured his short æra. He appears to have died without issue before the year 1165, and to have been succeeded in estate by his next brother, whom I will call—
  HERBERT FITZ HERBERT (II.).
  11 Carta Antiquæ, R. no. 33. Dugdale, and I think all Writers on the Extinct Peerage, have misrepresented this Charter as in favour of Herbert fitz Herbert.

I command you to protect and maintain the lands and all the tenures of the aforesaid archbishop, and not to permit anyone to take anything from them except through him. Furthermore, if anything has been unjustly taken from them since he became archbishop, you are to ensure that it is all restored to him, so that I may hear no further complaint regarding this matter.

Witnesses to this are, etc.
28.  Confirmation by William, archbishop of York, to the canons of Nostell, of the church of Weaverthorpe, which he gave when he was treasurer of York; and notification that Adelwald, bishop of Carlisle, has contritely surrendered the priorship of the church of St. Oswald, which he had for many years held in his own hand, and has granted licence to the canons to elect a prior; whereupon they have elected from amongst themselves dom.

This roughly translates as:
  William, by the grace of God archbishop of York, to all the sons of holy mother church, both present and future, sends eternal greeting in the Lord. Let it be known to you all that, out of regard for charity, I have granted to God, to the church of Saint Oswald of Nostell, and to the canons serving God there, the church of Wiverthorpe with all its appurtenances, which belongs to the fee of saint Peter dating from the time when I was treasurer of the church of Saint Peter. This grant was made in the presence of the venerable Thurstan, then archbishop of that same church, and the entire chapter of the same church, as a pure and perpetual alms for their sustenance and for the support of hospitality. Furthermore, to ensure that this donation remains valid and unshaken, we confirm the aforementioned church to the aforesaid canons, and, in our capacity as archbishop, we ratify this present document with the protection of our seal. Deeming it fitting that this matter should come to the knowledge of many, we have decided, upon careful deliberation, to commit it to writing. Let the present generation and all future posterity know that Adelwold, bishop of Carlisle, moved by a prick of conscience, voluntarily relinquished the priory of the church of Saint Oswald, which he had held in his own hands for many years, and granted the canons of that place the license and freedom to elect a prior for themselves. Supported by his counsel and assistance, they chose from among the brethren lord Sanard, a man of integrity, distinguished for both his learning and his way of life, and presented their choice to us and to the chapter of York. We graciously accepted him as prior and have confirmed their election by means of this present charter. It is therefore our will that no one should presume to inflict any injury or indignity upon them regarding the aforementioned church or their election. Should anyone, however, presume to attempt anything contrary to this document of ours, let him know that he shall incur the curse of Blessed Peter and our own. Given, etc.

  Fortunately we are able to fix the issue of this charter to the earlier period of archbishop William’s tenure of the see of York. John of Hexham tells us that Thurstan, provost of Beverley, died in the time of archbishop Henry, namely in or very shortly before 1152. Thurstan’s attestation of this charter thus fixes the date during the period 1144-1146, and that of Everard de Ros supports this conclusion. The fact that the grantor did not use his own seal, but that apparently of his predecessor, adds weight to this conclusion.
 This roughly translates as:
  William, by the grace of God archbishop of York, to the clergy, the people, and all the faithful, both those to come and those now living, who uphold this charter well and firmly, sends greetings and a blessing in perpetuity. Be it known to all of you that I have granted, given, and confirmed by the testimony of this present charter the status of a free borough to the town of Beverley and to the burgesses dwelling therein, following the model of the free borough of York and the same legal liberties that my predecessor, archbishop Thurstan, a man of venerable memory, granted and gave to them; saving, however, the established customs of Saint John, and saving our own rights, including the collection of rents. Furthermore, regarding the legal liberties, I have granted and given to these same burgesses the right to hold their own merchant guilds and legal pleas, enjoying the same liberties and customs among themselves as the burgesses of York do among themselves. It is my will that the statutes of this guild-hall should serve the benefit of the entire township, the honor of God and Saint John, the canons, and all the people of the said town. Moreover, I have granted them the right to collect tolls in perpetuity, in exchange for a payment of 18 marks annually, except during three specific feasts. During these times, the right to the tolls reverts to us and the canons. These occasions are: the feast of Saint John the confessor in May, specifically from the third hour (terce) on the eve of the feast until the evening of the feast day itself. If a market day should fall on that eve, or on the day immediately following the feast, the market shall be held within the churchyard. The same arrangement shall apply to the feast of the translation of Saint John. As for the great feast, namely, the nativity of Saint John the Baptist, the arrangement shall follow the established custom of Saint John, lasting from the feast of Saint Botolph until the third day after the feast. And if a market day should fall on any of the three days preceding a feast, or on the day following a feast, it shall be held in the cemetery. Furthermore, regarding these three feasts, determined in this manner, I have granted the burgesses themselves full exemption and release from all tolls. Moreover, by the testimony of this charter, I have confirmed for the same burgesses the right of free entry and exit, specifically regarding woodlands, open plains, marshlands, and other common lands, in accordance with the rights concerning such common lands as sworn to and attested by the elders of the town, with the exception of meadows and standing crops; all this to be held in the best, freest, and most generous manner ever granted or bestowed upon these burgesses by our venerable predecessor, the aforementioned Thurstan.

  William Fitz-Herbert was a younger son of Herbert, the chamberlain to Henry I, and of Emma, sister of Stephen of Blois, afterwards king. His name occurs in the roll of the sheriff of Wiltshire for 1130 as having obtained remission of Danegeld amounting to 14s.1 He was not there described as Treasurer of York.
  By this charter the king granted 2 churches and a chapel for a prebend for the said William, who had then been appointed to the office of Treasurer of York. Thomas II is said to have made 2 prebends, one of which was thought by Drake to have been Weighton;  but that could not have been so.
  The above grant was made between 28th May 1133, when Nigel, nephew of Roger, bishop of Salisbury, was nominated bishop of Ely, and 5th August following, when Henry took final leave of England.

  WILLIAM FITZ HERBERT was already a Wiltshire Landowner in 1130. About the same time he is stated to have held the ecclesiastical office of Treasurer of York. There is a Charter of King Stephen, dated at York, which, notwithstanding two errors of transcription in its testing-clause, I venture to date in February or March 1136. Thereby the King concedes to William, Treasurer of York, his Chaplain, the Churches which the said William holds of the Fee of his brother, Herbert, and among them the Churches of Laundesbrough and Wiverthorpe. He is to hold them as freely, etc., “as his Father and his brother Herbert gave them to him, and as the Charter of King Henry doth testify.”7 On Sunday, September 26, 1143, William fitz Herbert was consecrated Archbishop of York by Henry, Bishop of Winchester, and in defiance of Theobald, Archbishop of Canterbury. He was deprived of his See by Pope Eugenius III., in 1147, but was restored by Pope Anastasius IV., in 1153. He died on June 8, 1154, and was Canonized by Pope Honorius III., in the thirteenth century.

Dictionary of National Biography vol 19 pp173-176 (ed. Leslie Stephen, 1889)
  FITZHERBERT, WILLIAM, (d. 1154), archbishop of York and Saint, is also called sometimes William of Thwayt (Chron. de Melsa, i. 114, Rolls Ser.) and most commonly SAINT WILLIAM OF YORK. He was of noble birth (WILLIAM OF NEWBURGH, i. 55, Rolls Ser.), and brought up in luxury (JOHN OF HEXHAM, c. 274, in TWYSDEN), but of his father Herbert very little is certainly known. John of Hexham calls him Herbert of Winchester, and says that he had been treasurer of Henry I. Hugh the Chanter (in RAINE, Historians of the Church of York, ii. 223) says Herbert was also chamberlain. Thomas Stubbs (ib. p. 390) calls him the ‘very strenuous Count Herbert,’ and says that his wife was Emma, the sister of King Stephen. But of her nothing else is known (FREEMAN, Norman Conquest, v. 315), and her very existence depends on the trustworthiness of a late authority. John of Hexham mentions that William was a kinsman of Roger, king of Sicily, but it is suspicious that no contemporary writer, even when speaking in some detail of William’s dealings with Stephen and his brother Henry of Winchester, says a word of his relationship to the king. One nephew of Stephen was almost elected archbishop before him. Another nephew of Stephen succeeded him as treasurer of York. It is hardly probable that William was a nephew of Stephen also.
  Many of William’s kinsfolk lived in Yorkshire, and his elder brother Herbert held lands there, to which he apparently succeeded about 1140. William himself probably became treasurer and canon of York before 1130, at latest before 1138 (DUGDALE, Monasticon, iv. 323-4, ed. Caley, &c.) In that capacity he accompanied Archbishop Thurstan on his visitation of St. Mary’s Abbey, and witnessed his charter of foundation of Fountains Abbey (WALBRAN, Memorials of Fountains, i. 157). He also joined his brother Herbert in conferring benefactions on the Austin Priory of Nostell (Rot. Chart. p.215). Stephen made him one of his chaplains, and granted him certain churches in the north which he had hitherto held of his brother in fee (Monasticon, vi. 1196).
  On the death of Archbishop Thurstan (February 1140) there were great disputes in the chapter as to the choice of his successor. When the election of Henry de Coilli, King Stephen’s nephew, had been determined upon, it was rendered ineffective by his refusal to comply with the papal request to resign the abbey of Fécamp on accepting the archbishopric. At last, in January 1142, the majority agreed to elect as their archbishop William the treasurer. Their choice was, however, hardly unfettered; for King Stephen strongly pressed for his election, and the presence of William, earl of Albemarle, in the chapter-house to promote it doubtless stimulated their zeal (JOHN OF HEXHAM, c. 268; cf. GERVASE, Op. Histor. i. 123, Rolls Ser.) A minority persisted in voting for the strict Cistercian, Henry Murdac of Fountains (HOVEDEN, i. 198, Rolls Ser.), and the whole of that famous order believed that bribes of the treasurer had supplemented the commands of the king. The archdeacon of York, Osbert, called Walter of London in John of Hexham and in the ‘Additions to Hugh the Chanter’ (RAINE, Historians of York, ii. 221), and other archdeacons hurried to the king to complain of the election. They were seized by Albemarle on their way and confined in his castle of Bytham, Lincolnshire. William meanwhile was well received by Stephen at Lincoln, and there received the restitution of his temporalities. But he was unable to obtain consecration from Archbishop Theobald, and Henry, bishop of Winchester, the legate, Stephen’s brother, who was his friend, could only direct him to go to Rome, where Richard, abbot of Fountains, William, abbot of Rievaulx, and his other enemies had already appealed against his election as tainted by simony and royal influence. A strong letter of St. Bernard to Innocent II (S. BERNARDI, Omnia Opera, i. 316, ed. Mabillon; also printed in WALBRAN, pp. 80-1), to the pope that he had made, showed that the whole influence of the Cistercian order was to be directed against William. For a time Innocent hesitated, but at last, in Lent 1143, he decided that William might be consecrated if William, dean of York, would swear that the chapter received no royal commands from Albemarle, and if the archbishop elect would clear himself on oath from the charge of bribery. These points were to be ascertained in England, whither William arrived in September. The Dean of York, who had in the meanwhile been made bishop of Durham, was unable to attend in person the council at Winchester, where the case was to be settled; but his agents gave the necessary assurances, and William’s innocence was so clearly established that all clamoured for his consecration. On 26 Sept. the legate Henry himself consecrated William in his own cathedral at Winchester (Additions to Hugh the Chanter, p. 222).
  William now ruled at York in peace, and St. Bernard could only exhort the abbot of Rievaulx to bear with equanimity the triumph of his foe (Epistolæ, cccliii. and ccclx. in Opera, i. 556, 561, ed. Migne). Meanwhile William busied himself in drawing up constitutions that prohibited the profane use of the trees and grass in churchyards, and prevented clerks turning the money received for dilapidations from the heirs of their predecessors to their own personal uses (WILKINS, Concilia, i. 425-6). On a visit to Durham William succeeded in reconciling the turbulent William Comyn with Bishop William his old friend. On the same day he enthroned the former dean of York as bishop in Durham Cathedral, and absolved Comyn from his sins against the church (SYMEON, Hist. Eccl. Dunelm. pp. 283-4, 292; also Anglia Sacra, i. 717).
  Though popular from his extraordinary kindness and gentleness, William was of a sluggish temperament. When in 1146 the cardinal bishop Hincmar arrived in England on a mission from the new pope, Lucius II, he brought with him the pallium for the new archbishop. Occupied, as was his wont, on other matters of less necessity (JOHN OF HEXHAM, c. 274), William neglected to obtain it from Hincmar at an early opportunity. Before long Lucius died. The new pope, Eugenius III, was a violent Cistercian and the slave of St. Bernard. The enemies of William took advantage of his accession to renew their complaints against William. Hincmar took his pall back again to Rome. Bernard plied Eugenius with new letters. Henry Murdac, who was now, through Bernard’s influence, abbot of Fountains, led the attack. In 1147 William was compelled to undertake a fresh journey to Rome to seek for the pallium. To pay his expenses he was compelled to sell the treasures and privileges of the church of York (ib. c. 279), and this of course became a new source of complaint against him. Yet even now most of the cardinals were in his favour, and Eugenius was much distracted between the advice of his ‘senate’ and the commands of the abbot of Clairvaux. At last he found a pretext against William in the fact that William of Durham had not personally taken the pledges required by Pope Innocent. Until this was done he suspended William from his archiepiscopal functions.
  Disgusted at his condemnation on a second trial for offences for which he had been already acquitted, William left Rome and found a refuge with his kinsman Roger the Norman, king of Sicily. He was entertained there by Robert of Salisbury (or Selby), the English chancellor of King Roger. Meanwhile his relatives and partisans in Yorkshire had revenged his wrongs by burning and plundering Fountains Abbey, the centre of the Cistercian opposition to him (WALBRAN, p. 101). This indiscreet violence added a new point to the passionate appeals of Bernard. In 1147 Murdac and the rest again appeared against William at a council held by Eugenius at Rheims. There, as the Bishop of Durham had omitted to purge the archbishop on his oath (Chron. de Mailros, s. a. Bannatyne Club), Eugenius finally deposed him from his see. The chapter were directed to proceed within forty days to a new election. As they could not agree on any one choice, Eugenius cut the matter short by consecrating at Trier Henry Murdac himself as archbishop of York (7 Dec. 1147). But such was William’s popularity that Murdac obtained scanty recognition in Yorkshire, where king and people continued to maltreat his followers (Additions to Hugh the Chanter, p. 225).
  William showed great resignation to his fate. His staunch friend Henry of Winchester gave him an asylum in his palace, and treated him with all the respect due to an archbishop. William made no complaints of his harsh treatment. He occupied himself in prayer and study. He renounced his former habits of luxury. As often as he could escape from the hospitable entertainment of Bishop Henry, he spent his days with the monks of Winchester, whose sanctity specially attracted him to eat and drink at their frugal table and sleep with them in their common dormitory (Ann. de Winton in Ann. Mon. ii. 54). He remained at Winchester until the death of Bernard and Eugenius in 1153 again excited hopes in him of restitution. He again hurried to Rome, where, without reflecting on the judgment passed against him, he besought the new pope, Anastasius IV, to show him mercy. His friend, if not kinsman, Hugh of Puiset, who was also seeking at Rome his recognition as bishop of Durham, did his best to support William’s requests. The famous Cardinal Gregory warmly espoused his cause. The death of Archbishop Murdac, on 14 Oct. 1153, made it easy for Anastasius to accede to William’s prayers. Without questioning the legitimacy of Murdac’s rule or reopening the suits decided against William, Anastasius was persuaded to pity his grey hairs and misfortunes. William was restored to the archbishopric, and for the first time received the pallium.
  William now returned to England. Passing through Canterbury he is said to have designated the archdeacon Roger as his successor as archbishop. He next proceeded to Winchester, and celebrated the Easter feast of 1154 in the city where he had resided when young, and which had afforded him a refuge in his troubles. Thence he turned his course towards his diocese. As he approached York the new dean and his old enemy, Archdeacon Osbert, endeavoured to prevent his entrance into the city by declaring their intention of appealing against his appointment. But William proceeded on his way undismayed by their hostility. A great procession of clergy and laity welcomed him into the town. The wooden bridge over the Ouse gave way under the pressure of the crowd, and many were precipitated into the river; but the prayers of William saved, as men thought, the lives of every one of them. In after years a chapel dedicated to William was erected on the stone bridge now thrown over the river to commemorate so signal a miracle. He entered York on 9 May.
  For the next month William ruled his church in peace, though the appeal of the chapter to Archbishop Theobald was fraught with fresh mischief. But William was no longer the worldling whose wealth and laxity had excited the suspicions of Cistercian zealots. With great humility he visited Fountains and promised full restitution for the injuries his partisans had inflicted upon the abbey. The official chroniclers of the abbey had in after times nothing to say against one who could make so complete a reparation (WALBRAN, i. 80). He also visited the new Cistercian foundation at Meaux, Yorkshire, and in its chapter-house solemnly confirmed the grants of Archbishop Murdac to the struggling community (Chron. de Melsa, i. 94, 108). On Trinity Sunday he was back at York, and when celebrating high mass in his cathedral on that festival was seized with a sudden illness. He struggled through the service and even appeared afterwards among the guests assembled in his house. But he felt that his end was near. Poison was at once suspected, and antidotes were administered. But he died on 8 June, eight days after his seizure, and Bishop Hugh of Durham buried his body in York Minster.
  Faction had risen to such a height at York that a circumstantial story soon gained credence among William’s friends that Osbert the archdeacon had caused his death by poisoning the eucharistic chalice. A clerk of William’s, named Symphorian, accused Osbert of the crime, in the presence of King Stephen, and long judicial proceedings ensued. Though the matter seems never to have been brought to a definite issue, so acute an observer as John of Salisbury was not satisfied of Osbert’s innocence (Ep. i. 158, 170, ed. Giles). William of Newburgh (i. 80-1), the most critical historian of the time, was, however, convinced by the absence of positive testimony, and the witness of an old monk of Rievaulx, then a canon of York, that William died of a fever. Gilbert Foliot (Ep. i. 152, ed. Giles) was indignant at the baselessness of the accusations against Osbert, but the true issue became rather obscured by clerical opposition to the desire of Stephen, and of the accuser, that the case should be tried in the royal court. The two biographers of William omit all reference to the story, and the writers who mention it generally qualify it as a rumour or gossip. Yet before long the misfortunes and sufferings of William brought worshippers to his tomb. He began to be reputed a martyr, and miracles were worked by him. It was believed that when the old minster was almost burnt down and the tomb burst open by the falling beam the silken robe which enveloped the saint’s incorruptible body was not consumed (Vita S. Will, in RAINE, ii. 279). The canons of York, who envied the local saints of Ripon and Beverley, were anxious for a saint of their own, and a movement was started for the canonisation of William. In 1223 holy oil exuded from his tomb (MATT. PARIS, Hist. Major, iii. 77, Rolls Ser.) A formal petition to Honorius III led to the usual investigations of his claims to sanctity (WALBRAN, i. 173-5, from Addit. MS. 15352). These, after some doubt, were so well established that in 1227 Honorius admitted him to the calendar of saints. On 9 Jan. 1283 his remains were translated into a shrine behind the high altar, through the exertions of Bishop Bek of Durham, and in the presence of Edward I and a distinguished company (details in RAINE, pp. 228-9, from York Breviary). But all the efforts of the York chapter could not secure for St. William more than a local fame; and his shrine, though not unfrequented, was never among the great centres of popular pilgrimage and worship. His festival was on 8 June, while his translation was commemorated on the Sunday next after the Epiphany.

Fasti eboracenses. Lives of the archbishops of York vol 1 pp220-233 (William Henry Dixon, enlarged by James Raine, 1863)
William Fitzherbert, better known under the name of St. William of York, was a person of noble origin. His father was Count Herbert, who is said, by Stubbs, to have been chamberlain and treasurer to king Henry; and his mother, Emma, was a grand-daughter of the Conqueror, and was sister to king Stephen; from his infancy, therefore, William was brought up in the lap of luxury and wealth.p
  About the year 1130 we find William, as treasurer of the church of York, witnessing archbishop Thurstan’s charter of foundation of the nunnery of Clementhorp. There is a deed, also, without a date, in which Henry I. grants the churches of Wallop and Wichtona, and the chapel of Grateleia, in which William the treasurer had a life interest, to be the corpus of a new prebend at York. I have seen a charter of king Stephen, in which that monarch grants to William, the treasurer of York, his chaplain, the churches of Weaverthorpe, Londcsburgh, Clcve, with their chapels, and the church of Stanton; all of which he held of the fee of his brother Herbert.s This probably is the nobleman whom Dugdale introduces in his Baronage,t and of whose parentage there has, hitherto, been nothing known.
  Archbishop Thurstan died in 1140, and the chapter of York seem to have had great difficulty in selecting a person to succeed him. At the instance of Henry de Blois, bishop of Winchester, and the king’s brother, they fixed upon his nephew, Henry de Sully. That ecclesiastic was the abbat of Fècamp in Normandy, and the pope would not allow him to become archbishop because he refused to give up his monastery. In January, 1141-2, the clergy again met to choose a president, and the majority fixed upon William, the treasurer. As he was one of the king’s nephews, the court influence seems to have been brought to bear upon the chapter, and William, earl of Albemarle, was present at the election, in which he took an especial interest. That nobleman, unfortunately, shewed himself a hasty partizan, and did much mischief to the cause of William. Master Walter, of London, and the rest of the York archdeacons were opposed to the choice which the clergy had made, and were on their way to the king to state their case, when the stout earl arrested them and shut them up in his castle at Bytham. In the meantime the archbishop-elect went to Stephen at Lincoln, and was kindly received, and invested with the temporalities of the see. The bishop of Winchester, another uncle, who was at that time the legate in England, then sent him to Rome.
  The opposition, however, was not so easily quelled, and the harsh measures of the earl of Albemarle would not allay it. The discontented party determined to follow William to Rome, and make their appeal to. the chief pontiff. It was a contest between the court and the most influential portion of the clergy. The clerical party was ably represented, and was backed by the reformers in the church, particularly by the Cistercians. The cause was heard in 1142 in the consistory of pope Innocent. Walter of London, the archdeacon, who had escaped from the clutches of Albemarle, presented the allegations against William, which were supported by William abbat of Rievaux, Richard abbat of Fountains, Cuthbert prior of Gisburgh, Waltheof the famous prior of Kirkham, and Robert the master of the hospital at York. William was charged by them with having secured his election by bribery. Innocent listened to what was said, but would make no decision at that time. He ordered both parties to present themselves before him on the third Sunday in Lent in the following year.
  They came to Rome at the appointed time in 1143, and the case was heard. The main point against the validity of William’s election was this, that the earl of Albemarle had come into the chapter-house, and had vitiated the proceedings by giving a message from the king that William should be chosen. The pope very properly declared that if, in addition to the personal denial of the imputation of undue influence by William himself, the dean of York would state on his oath that no such message from the king had been delivered, that then the archbishop-elect might be consecrated. The dean also, who was not present at the consistory, was to be allowed, if he chose, to take the oath by deputy. That dignitary had other things to think of, as he had just been nominated to the see of Durham by the prior and the clergy. William returned from Rome in September 1143, and following the advice of the legate, submitted his case to a council which was held at Winchester. Every one seemed, not to request, but to demand, his consecration; and not a murmur was heard against anything that he had done. The bishop of Durham had been expected to take the oath about the election in the chapter-house at York, which had been prescribed to him by the pope, but he was unavoidably absent. Ralph bishop of Orkney, Sanaricus the abbat of St. Mary’s, York, and Benedict abbat of Whitby, took it in his behalf, and swore to the absence of simony and undue influence. What more could be required? On the 26th of September William was consecrated at Winchester by the bishop of that diocese, who was his uncle and his friend.
  In 1145 cardinal Hincmar, a legate from Lucius the new pope, visited England, and brought with him a pall for William. They did not meet, for William was a person of an easy and indolent disposition, and saw no reason for promptitude or haste. In the meantime the pope died and was succeeded by Bernard, the abbat of the house of St. Anastatius at Rome, under the title of Eugenius III. He was a rigid Cistercian, and hung upon the lips of St. Bernard. The opponents of William now began most ungenerously to reopen the old sore. They could carry the day now, as they thought, and they resolved to try. They were decidedly in the wrong. William had complied with all the conditions which Innocent had laid down, and his consecration had been regular and proper. Why was he to be opposed? There must have been some personal feeling prompting his opponents, that curse which, under the colour of conscience and justice, has in every age instigated so many great men to be persecutors and maligners. William about this time shewed his love of peace by effecting a reconciliation between the bishop of Durham and the turbulent Comyn. With Alan, earl of Richmond, he was not so fortunate.
  Hincmar returned to Rome in 1145, carrying the pall with him, and, in the following year, William went in quest of it himself to the court of Eugenius. The charges against him had been revived by the Cistercians, Henry Murdac, the abbat of Fountains, taking a prominent part in the attack. But William had a more serious opponent in St. Bernard. That great man, whose zeal in this instance orerpowered his judgment, had been a constant opponent of the appointment of William. He wrote strong letters against him to popes Celestine and Innocent and the cardinals. He now exerted for the same purpose the immense influence which he exercised over Eugenius. The cardinals, however, were in William’s favour, and the pope was in a difficulty. At length Eugenius resolved to deprive him, until the bishop of Durham should take the oath which had been formerly required from him, and the cardinal-bishop of Ostia read the sentence of deprivation. This was unfair treatment. It was tantamount to trying a person a second time for the offence of which he had already been acquitted. William left Rome in disgust, and spent some time at the court of Roger king of Sicily, as the guest of Robert, the chancellor of that monarch, who was an Englishman by birth. Whilst he was staying there, the indignation of Eugenius was aroused by the account of the attack upon Fountains abbey which had been made by some of William’s indiscreet partizans. This unfortunate occurrence, together with the urgent appeals of St. Bernard, probably induced the pope to take summary measures against William. Murdac and the York clergy were present at a council which was held at Rheims in 1147, over which Eugenius himself presided, and there, in comjjliance with their request, William was removed from his archbishopric, and the bishop of Durham and the chapter of York were ordered to proceed to the election of another primate within forty days after the receipt of the papal mandate.
  Henry Murdac now stepped for awhile into the see of York, as has been already stated, and William, returning from the Sicilian court, found an asylum with his uncle at Winchester. The opposition that was made to Murdac shews the sympathy which was felt for the ejected prelate. At his uncle’s palace William received all the honours that could be paid to an archbishop. High and low regarded him with affection and compassion. He made no murmur himself against the sentence of Eugenius.
    “His duty is to stand and wait,
      In resigniation to abide
      The shock, and finalty secure
      O'er pain and grief a triumph pure.”
The luxury and inertness of his previous life seem to have deserted him. He was an altered man. He was sedulous in his devotions and study. Not a harsh word against those who had wronged him ever passed his lips. Affliction had wrought in him the end for which it was designed. It had given him
    “A soul by force of sorrows high
      Uplifted to the purest sky
      Of undisturbed humanity.”
William seems to have lived in retirement at Winchester during the whole of the archiepiscopate of Murdac. When that prelate died in 1153 the hopes of the sufferer again arose. The majority of the chapter of York elected him their superior, and he hastened at once to Rome, not to complain of his past wrongs, but to beg for present justice. All now seemed willing to befriend him. Gregory, one of the most influential of the cardinals, took up his cause with warmth, and William’s cousin, Hugh de Puiset, who was then at Rome to expedite his own consecration as bishop of Durham, did what he could for him. Anastatius, the new pope, was moved by the account of his trials and the earnestness of his pleading, and restored him to the honours of which he had been deprived, giving him the wished-for pall. William returned to England with a light heart, and kept the Easter of 1154 at Winchester, where he had so long resided. Whilst he was in the South he is said to have paid a visit to Canterbury, and there he had much friendly intercourse with Roger the archdeacon. “That man shall be my successor,”' is said to have been his remark. And so he was.
  William now set out for York. Before he had entered into the city he was met by Robert the dean and archdeacon Osbert, who had withstood his election by the chapter, and they, hoping to prevent his approach to their church, announced their intention of appealing from the decision of their brethren to archbishop Theobald. William’s progress, however, was not delayed by their opposition. He reached the city on the 9th of May, a vast and rejoicing crowd accompanying him. As the party was crossing the Ouse, the bridge, which was then made of wood, gave way, and a number of persons were precipitated into the river. William is said to have wrought a miracle in their behalf. We are told that he made his prayers with tears to God for the sufferers, and, making over them the sign of the cross, they were all saved. When a bridge of stone was erected at that place, a chapel upon it, dedicated to St. William, reminded the wayfarers of the legend.
  William was in York but thirty days. On Trinity Sunday he officiated in the minster, and almost before the service was over he was seized with a very sudden and alarming attack of illness. He returned to his residence, which was hard by, and a banquet was prepared for his friends, whilst the archbishop sought his chamber, which he never left alive. Like many others, he had a presentiment of what was coming on. For eight days he was on the bed of sickness, and then, on the 8th of June, he died. There was a story current in the middle ages to the effect that he had been poisoned by something which his clerks or enemies had put into the eucharistic wine, and on that account he was afterwards regarded as a martyr. There is, however, no allusion to this tale either in the MS. life of William, or in the account of him by Stubbs. William of Newburgh, also, speaks contemptuously of the report, and denies it on the authority of a monk of Rievaux of his acquaintance, who had been intimately connected with the archbishop, and had been present when he died. William died of a fever, and the suddenness of the attack made his friends imagine that he had been poisoned. Archdeacon Osbert, who had constantly opposed William, was looked upon as the culprit. Symphorian, one of the clerks of the deceased prelate, charged him with the crime in the presence of the king and coimcil, and was desirous that the matter might be decided either by the combat or the ordeal. Osbert professed his willingness to abide by the decision of an ecclesiastical tribunal. We are told by John of Salisbury that he failed to purge himself from the charge, but we do not know to what test he was subjected. Gilbert Foliot, however, expresses a strong opinion as to the innocence of the accused person, and the injustice of the proceedings against him.
  William was interred in the minster of York by his old friend bishop Pudsey. His sufferings and character, the gentleness of his disposition and his untimely end, won for him general sympathy. The church of York had no saint at that time peculiar to itself, and the chapter were most anxious, if possible, to procure the canonization of William. Thirty-six miracles are said to have been wrought through the mediation of the deceased archbishop, and a holy oil, one of the mediæval accompaniments of supposed sanctity, is said to have flowed from his tomb. In 1227 the archbishop and the chapter of York entreated Honorius III. to enter William on the calendar, sending as their representatives Godard the penancer, Elias Bernardi, one of the canons, and Laurence, canon of Aquileia. Indulgences were also granted by the archbishop of Canterbiuy, the bishops of Rochester, London, Lincoln, Ardfert and Dublin, to those who visited the tomb; the papal assent, however, was not immediately given, and a commission seems to have been issued to make a full enquiry into the circumstances of the case. The canonization was not completed until the pontificate of Nicholas III., when it was effected by the money and urgent entreaties of the bishop-elect of Durham, the magnificent Anthony Bek, who was represented at Rome by his cousin Stephen de Mauley, archdeacon of Cleveland. The depositio of William was commemorated on the 8th of June, and his translation on the 8th of January. At a council held in the minster on the 29th of October, 1478, the last-mentioned ceremonial was transferred to the Sunday next after the Epiphany, and it was ordered to be observed as a double and principal festival.
  The remains of William were interred in the nave of York minster, near the south-west pillar of the lantern; they were removed in solemn state to a nobler resting-place in the choir, on the 8th of January, 1283-4. On no other occasion has the cathedral received within its walls a more illustrious assemblage. A double ceremony brought it there that day—the translation of St. William, and the consecration of that noble-minded man who had secured for the church of York the canonization of its archbishop. Bek, who was called
    “Le plus vaillant clerk de roiaume,”
was surrounded by the chief estates of England, including Edward I. and his gentle consort. The king had recently fallen from an eminence, and had escaped unhurt. He ascribed his good fortune to the agency of St. William, and hastened to York to shew his gratitude by being present at the translation of his body. The ceremonial on that occasion has been detailed with an interesting minuteness.
  On the night of the 6th of January, archbishop Wickwaine, attended by the dean and the canons, went into the minster, Anthony Bek, and his brother Thomas, the bishop of St. David’s, accompanying them. The solemnity of the place and the time did not appal them, for they were bent upon a holy work. They went to the tomb of William, and prostrated themselves in lowliest obeisance. When their devotions were finished, they arose and removed reverently the stone which served as a lid to the sarcophagus in which the archbishop was laid. The body still bore the vestments in which Puiset had committed it to the grave, and was steeped and redolent, as the narrator tells us, with an odoriferous oil. They began by removing the paten and chalice which lay beside the remains; and then the archbishop and his companions carefully and devoutly gathered together the bones from the head downwards, and rolling them up, with the other things which were there, placed them for the night in a capsule or case, which was sealed up and concealed until the morrow. On the following day the reliques were minutely examined, and everything that pertained to the body was deposited and secured in an appropriate feretory. On the day after this was the festival of the translation; and about the hour of prime the royal party, and a goodly company of lords and prelates, were assembled in the church. The archbishop preached a sermon in which he expatiated largely, no doubt, upon the merits of his now sainted predecessor. When this was over, the feretory was raised upon the shoulders of the king and others, and was borne, probably with joyous music, around a portion of the choir to the elevated shrine in which it was henceforward to be preserved.
  The place in which the feretory was deposited was in all probability behind the high altar, in the vacant space between it and the eastermost screen. It was here that the shrine was erected and decked with the offerings of the worshippers. It seems to have been divided into two parts, one fitting into the other. The smaller part, in which the reliques were enclosed, could be lifted, and seems to have been borne processionally, on solemn occasions, through the minster and the city. There were appended to it the little gifts which piety or superstition had suggested—images, beads, rings, girdles, and jewels of every description, of gold, silver, or precious stone. The skull of the saint was kept by itself in a case of silver gilt. It was most richly decorated. When the storm of the Reformation broke over the church, this relique had a curious fate. On the 24th of October, 1541, the dean, Richard Layton, who was a minion of the king, caused a chapter act to be passed by which the head and its omamcnts were to be appropriated to the use of the cathedral. The bones of William were now unhoused. In May, 1732, Mr. Drake, the historian of York, removed the stone in the nave of the minster under which the remains of William were said to have been deposited, and found under it, in a leaden box, a number of bones huddled carelessly together without any order or arrangement. It seems probable from this that the reliques had been laid in their old resting-place after the feretory and the capsule had been destroyed.
  The chapter of York in the middle ages paid great honour to St. William, although, perhaps, his shrine had a less brilliant reputation than that of any other Northern saint. As early as 1230 a chantry was founded at the place of his interment by Elias Bernardi, one of the canons who had been most anxious to secure his canonization. A chapel dedicated to him was erected upon Ouse bridge, to commemorate what had occurred when William came into the city before his death. In the fifteenth century, a college, which bears his name, was built for the use of the ecclesiastics in the minster, at the east end of the cathedral. A considerable portion of it is now in existence. There is still in the choir of the church of York “a storied window richly dight,” detailing the principal events in William’s life. The monks of Meaux treasured carefully among their reliques some of the hair of the sainted archbishop.
  St. William is not without his biographer. Some unknown writer has drawn up an account of his life, which is now preserved in the British Museum among the Harleian MSS., No. 2. It is in a hand of the twelfth century, and belonged at one time to Thornton abbey. The style is very inflated and diffuse, and the work contains nothing that we were not previously acquainted with through the pages of John of Hexham and William of Newburgh. There was another life of William among the MSS. formerly belonging to Sir Simonds d’Ewes, which I have been unable to trace. Capgrave, also, gives a short account of him in his Legenda, which has been transferred by the Bollandists to their Acta Sanctorum. The compilers of that invaluable collection were unacquainted with the existence of any unpublished life of the saint.
  I now give two hymns addressed to St. William. The first was discovered accidentally in the Cottonian library. Alford, in his Annals, could only quote a few lines of it; and the writer of the life in the Acta Sanctorum, when he alludes to it, says regretfully, “totum utinam dedisset.” The second is gathered from the Responsoria, etc., in the service for the translation of St. William in the breviaries of the York use. To those who are accustomed to hexameters and pentameters the metres will be novel and refreshing. … [the hymns, in Latin, are printed in full]

    ST. WILLIAM, ARCHBISHOP OF YORK, C.
  HE was son of earl Herbert, and Emma, sister to king Stephen. He learned from his infancy that true greatness consists only in humility and virtue; and renounced the world in his youth, employing his riches to purchase unfading treasures in heaven by works of mercy to the poor, and giving himself wholly to the study and practice of religion. Being promoted to holy orders, he was elected treasurer in the metropolitical church of York, under the learned and good archbishop Thurstan. When that prelate, after having held his dignity twenty years, retired among the Cluniac monks at Pontefract to prepare himself for his death, which happened the year following, St. William was chosen archbishop by the majority of the chapter, and consecrated at Winchester in September, 1144, according to Le Neve’s Fasti.1 But Osbert, the archdeacon, a turbulent man, procured Henry Murdach. a Cistercian monk of the abbey of Fountains, who was also a man of great learning and a zealous preacher, to be preferred at Rome, whither William went to demand his pall, and to plead the cause of his constituents rather than his own. Being deprived by pope Eugenius III., in 1147, he, who had always looked upon this dignity with trembling, appeared much greater in the manner in which he bore this repulse than he could have done in the highest honors. Being returned into England, he went privately to Winchester, to his uncle Henry, bishop of that see, by whom he was honorably entertained. He led at Winchester a penitential life, in silence, solitude, and prayer, in a retired house belonging to the bishop, bewailing the frailties of his past life with many tears, for seven years. The archbishop Henry then dying in 1153, and Anastasius IV. having succeeded Eugenius III. in the see of Rome, St, William, to satisfy the importunity of others, by whom he was again elected, undertook a second journey to Rome, and received the pallium from his holiness. The saint on his return was met on the road by Robert de Gaunt, dean, and Osbert, archbishop of the church of York, who insolently forbade him to enter that city or diocese. He received the affront with an engaging meekness, but pursued his journey. He was received with incredible joy by his people. The great numbers who assembled on that occasion to see and welcome him, broke down the wooden bridge over the river Ouse, in the middle of the city of York, and a great many persons fell into the river. The saint seeing this terrible accident, made the sign of the cross over the river, and addressed himself to God with many tears. All the world ascribed to his sanctity and prayers the miraculous preservation of the whole multitude, especially of the children, who all escaped out of the waters without hurt. St. William showed no enmity and sought no revenge against his most inveterate enemies, who had prepossessed Eugenius III. against him by the blackest calumnies, and by every unwarrantable means had obstructed his good designs. He formed many great projects for the good of his diocese, and the salvation of souls, but within a few weeks after his installation was seized with a fever, of which he died on the third day of his sickness, on the 8th of June, 1154.† He was buried in his cathedral; and canonized by pope Nicholas III. about the year 1280. At the same time his body was taken up by archbishop William Wickwane, and his relics put into a very rich shrine, and deposited in the nave of the same metropolitan church in 1284. The feast of his translation was kept on the 7th of January.2 King Edward I. and his whole court assisted at this ceremony, during which many miracles are attested to have been wrought. A table containing a list of thirty-six miracles, with a copy of an indulgence of one hundred and forty days to all who should devoutly visit his tomb, is still to be seen in the vestry, but no longer legible, as Mr. Drake mentions.3 The shrine, with its rich plate and jewels, was plundered at the reformation; but the saint’s bones were deposited in a box within a coffin, and buried in the nave, under a large spotted marble stone.

  † Hoveden advances that poison had been put into the chalice when he said mass. But Gulielmus Neubrigensis, a canon regular, a Yorkshire-man, an elegant and most diliient historian of that very time, in his history De Rebus Anglicis sui Temporis, confutes that groundless surmise of the vulgar.

Death: 8 June 1154, eight days after suffering a seizure in his church. Accusation of poisoning were made to the king against a rival, archdeacon Osbert, and a royal trial was scheduled, but the accusation was never proven.

Fasti eboracenses. Lives of the archbishops of York vol 1 pp226-227 (William Henry Dixon, enlarged by James Raine, 1863)
  William was in York but thirty days. On Trinity Sunday he officiated in the minster, and almost before the service was over he was seized with a very sudden and alarming attack of illness. He returned to his residence, which was hard by, and a banquet was prepared for his friends, whilst the archbishop sought his chamber, which he never left alive. Like many others, he had a presentiment of what was coming on. For eight days he was on the bed of sickness, and then, on the 8th of June, he died. There was a story current in the middle ages to the effect that he had been poisoned by something which his clerks or enemies had put into the eucharistic wine, and on that account he was afterwards regarded as a martyr. There is, however, no allusion to this tale either in the MS. life of William, or in the account of him by Stubbs. William of Newburgh, also, speaks contemptuously of the report, and denies it on the authority of a monk of Rievaux of his acquaintance, who had been intimately connected with the archbishop, and had been present when he died. William died of a fever, and the suddenness of the attack made his friends imagine that he had been poisoned. Archdeacon Osbert, who had constantly opposed William, was looked upon as the culprit. Symphorian, one of the clerks of the deceased prelate, charged him with the crime in the presence of the king and coimcil, and was desirous that the matter might be decided either by the combat or the ordeal. Osbert professed his willingness to abide by the decision of an ecclesiastical tribunal. We are told by John of Salisbury that he failed to purge himself from the charge, but we do not know to what test he was subjected. Gilbert Foliot, however, expresses a strong opinion as to the innocence of the accused person, and the injustice of the proceedings against him.

Fasti eboracenses. Lives of the archbishops of York vol 1 pp227-230 (William Henry Dixon, enlarged by James Raine, 1863)
  William was interred in the minster of York by his old friend bishop Pudsey. His sufferings and character, the gentleness of his disposition and his untimely end, won for him general sympathy. The church of York had no saint at that time peculiar to itself, and the chapter were most anxious, if possible, to procure the canonization of William. Thirty-six miracles are said to have been wrought through the mediation of the deceased archbishop, and a holy oil, one of the mediæval accompaniments of supposed sanctity, is said to have flowed from his tomb. In 1227 the archbishop and the chapter of York entreated Honorius III. to enter William on the calendar, sending as their representatives Godard the penancer, Elias Bernardi, one of the canons, and Laurence, canon of Aquileia. Indulgences were also granted by the archbishop of Canterbiuy, the bishops of Rochester, London, Lincoln, Ardfert and Dublin, to those who visited the tomb; the papal assent, however, was not immediately given, and a commission seems to have been issued to make a full enquiry into the circumstances of the case. The canonization was not completed until the pontificate of Nicholas III., when it was effected by the money and urgent entreaties of the bishop-elect of Durham, the magnificent Anthony Bek, who was represented at Rome by his cousin Stephen de Mauley, archdeacon of Cleveland. The depositio of William was commemorated on the 8th of June, and his translation on the 8th of January. At a council held in the minster on the 29th of October, 1478, the last-mentioned ceremonial was transferred to the Sunday next after the Epiphany, and it was ordered to be observed as a double and principal festival.
  The remains of William were interred in the nave of York minster, near the south-west pillar of the lantern; they were removed in solemn state to a nobler resting-place in the choir, on the 8th of January, 1283-4. On no other occasion has the cathedral received within its walls a more illustrious assemblage. A double ceremony brought it there that day—the translation of St. William, and the consecration of that noble-minded man who had secured for the church of York the canonization of its archbishop. Bek, who was called
    “Le plus vaillant clerk de roiaume,”
was surrounded by the chief estates of England, including Edward I. and his gentle consort. The king had recently fallen from an eminence, and had escaped unhurt. He ascribed his good fortune to the agency of St. William, and hastened to York to shew his gratitude by being present at the translation of his body. The ceremonial on that occasion has been detailed with an interesting minuteness.
  On the night of the 6th of January, archbishop Wickwaine, attended by the dean and the canons, went into the minster, Anthony Bek, and his brother Thomas, the bishop of St. David’s, accompanying them. The solemnity of the place and the time did not appal them, for they were bent upon a holy work. They went to the tomb of William, and prostrated themselves in lowliest obeisance. When their devotions were finished, they arose and removed reverently the stone which served as a lid to the sarcophagus in which the archbishop was laid. The body still bore the vestments in which Puiset had committed it to the grave, and was steeped and redolent, as the narrator tells us, with an odoriferous oil. They began by removing the paten and chalice which lay beside the remains; and then the archbishop and his companions carefully and devoutly gathered together the bones from the head downwards, and rolling them up, with the other things which were there, placed them for the night in a capsule or case, which was sealed up and concealed until the morrow. On the following day the reliques were minutely examined, and everything that pertained to the body was deposited and secured in an appropriate feretory. On the day after this was the festival of the translation; and about the hour of prime the royal party, and a goodly company of lords and prelates, were assembled in the church. The archbishop preached a sermon in which he expatiated largely, no doubt, upon the merits of his now sainted predecessor. When this was over, the feretory was raised upon the shoulders of the king and others, and was borne, probably with joyous music, around a portion of the choir to the elevated shrine in which it was henceforward to be preserved.
  The place in which the feretory was deposited was in all probability behind the high altar, in the vacant space between it and the eastermost screen. It was here that the shrine was erected and decked with the offerings of the worshippers. It seems to have been divided into two parts, one fitting into the other. The smaller part, in which the reliques were enclosed, could be lifted, and seems to have been borne processionally, on solemn occasions, through the minster and the city. There were appended to it the little gifts which piety or superstition had suggested—images, beads, rings, girdles, and jewels of every description, of gold, silver, or precious stone. The skull of the saint was kept by itself in a case of silver gilt. It was most richly decorated. When the storm of the Reformation broke over the church, this relique had a curious fate. On the 24th of October, 1541, the dean, Richard Layton, who was a minion of the king, caused a chapter act to be passed by which the head and its omamcnts were to be appropriated to the use of the cathedral. The bones of William were now unhoused. In May, 1732, Mr. Drake, the historian of York, removed the stone in the nave of the minster under which the remains of William were said to have been deposited, and found under it, in a leaden box, a number of bones huddled carelessly together without any order or arrangement. It seems probable from this that the reliques had been laid in their old resting-place after the feretory and the capsule had been destroyed.
  The chapter of York in the middle ages paid great honour to St. William, although, perhaps, his shrine had a less brilliant reputation than that of any other Northern saint. As early as 1230 a chantry was founded at the place of his interment by Elias Bernardi, one of the canons who had been most anxious to secure his canonization. A chapel dedicated to him was erected upon Ouse bridge, to commemorate what had occurred when William came into the city before his death. In the fifteenth century, a college, which bears his name, was built for the use of the ecclesiastics in the minster, at the east end of the cathedral. A considerable portion of it is now in existence. There is still in the choir of the church of York “a storied window richly dight,” detailing the principal events in William’s life. The monks of Meaux treasured carefully among their reliques some of the hair of the sainted archbishop.

wikipedia (William of York)
The earliest shine to William in York Minster dates to the 1220s in which William's sarcophagus was buried 10 inches (25 cm) into the floor and a shrine structure erected above it – this left the lid of the sarcophagus proud of the structure to be accessible to pilgrims. In 1284 Bishop Bek paid for the translation of William's body to a new shrine in the choir behind the high altar; no trace of the shrine has been recorded. A tomb shrine was built around 1330 on the site of William's original burial place in the eastern-most bay of the nave. The latest, principal shrine was located near the Minster's High Altar was built in 1471–1472.
  There is no evidence of large scale pilgrimage to William's shrines. However, numerous panels from the stained glass window in the Minster depict petitioners and worshippers at the shrines. The upper face of William's sarcophagus has been worn smooth, probably from the hands of pilgrims touching it.
  In 1541 the Privy Council ordered the demolishing of all of the shrines in York Diocese. William's shrines were taken apart and buried at Precentor's Court. Fragments of the shrines were discovered during the 18th through 20th centuries. The sarcophagus containing William's remains was rediscovered in 1732 and again in 1968. His remains are now held in a shrine in the crypt of York Minster. Parts of the shrines are in the Yorkshire Museum. During celebrations of the 800th anniversary of William's canonisation in 2026, these pieces were put on display at York Minster alongside a digital recreation of the shrine.
