  Wikipedia
  
  William de Mowbray (c. 1173-c. 1224), a landowner with Yorkshire estates centering on Thirsk and Lincolnshire lands in the Isle of Axholme, was son of Nigel de Mowbray and his wife Mabel, probably the daughter of William de Patri. In the Histoire des Ducs de Normandie he is described as being as small as a dwarf, but very generous and valiant.
  
  There was much in William’s background and personal circumstances that can be seen, with hindsight, as pointing the way to his involvement in the rebellion against King John. His forebear, Roger de Mowbray, had taken part in the great uprising against Henry II in 1173-4, which had convulsed the whole Angevin world. He himself had become entangled in financial dealings with King John which were to cost him dearly.
  
  His problems lay in his family’s early rise to power, specifically in their acquisition from Henry I a century before of the lands of Robert de Stuteville, a supporter of Henry’s brother Robert Curthose in his failed bid for the English crown, and who had forfeited his property to Henry. In 1200 Robert’s descendant, William, reactivated his family’s claim against the Mowbrays, and in that year William offered the sum of 2000 marks (over £1300) to John to secure a judgement in the matter. When the case was brought before the king’s justices, however, it ended in a compromise, and one highly favorable to Stuteville. William was nonetheless still under obligation to pay and, like others before him, had little alternative but to borrow from the Jews. William had gambled everything on the favorable outcome of a risky legal action and had failed. It is clear that, when he embarked on rebellion against John, he had nothing to lose.
  
  Mowbray was taken prisoner at the battle of Lincoln in May 1217, and had to surrender the manor of Banstead in Surrey, which had formed his mother’s marriage portion, to Hubert de Burgh as the price of redemption. His family never succeeded in recovering the estate.
  
  Mowbray founded the chapel of St Nicholas at Thirsk, and was a benefactor of his father’s foundation. He is listed as having been buried at Byland Abbey along with his mother and brother. (Wikipedia "Byland Abbey")
  
  Mowbray was typical those lords, particularly in northern England, who had suffered at the hands of John, felt a burning sense of grievance, and were longing for the opportunity to get their own back.

  === William de Mowbray, Magna Charta Surety ===
  William de Mowbray, Magna Charta Surety, successor to his father, in the 6th year of King Richard I., paying 100 pounds for his relief, had livery of his lands. This feudal lord, upon the accession of King John, was tardy in pledging his allegiance, and at length only swore fealty upon the condition that "the king should render to every man his right." At the breaking out of -the baronial war, it was no marvel then, that he should be found one of the most forward of the discontented lords, and so distinguished, that he was chosen with his brother, Roger, among the twenty-five celebrated barons appointed to enforce the observance of the Magna Charta. At one time he was governor of York Castle. He was a party to the "Covenant for holding the City and Tower of London," and one of those whom the Pope excommunicated. In the reign of King Henry III., adhering to the same cause, he was at the battle of Lincoln, and taken prisoner there, when his lands were seized, and bestowed upon William Marshall, the younger, the Surety of the Magna Charta, but he was subsequently allowed to redeem them. After which he appears to have attached himself to the king, and was with the royal army at the siege of Bitham Castle, in Lincolnshire. He married Agnes Albini, daughter of the Earl of Arundel.

History It was founded as a Savigniac abbey in January 1135 and was absorbed by the Cistercian order in 1147.[1] It was not an easy start for the community which had had to move five times before settling at New Byland, near Coxwold in 1177.[2] Its early history was marked by disputes with no fewer than four other religious establishments: Furness Abbey, Calder Abbey, Rievaulx Abbey and Newburgh Priory.[3] However, once it had overcome these setbacks, it was described, in the late 14th century, as "one of the three shining lights of the north".[1] Its financial success was not as great as such abbeys as Rievaulx, but it was famed for its sheep rearing and wool exports. Its church was said to be among the finest 12th-century churches in Europe.[4] In October 1322, King Edward II was at Byland Abbey when the Battle of Old Byland took place. The marauding Scots caught Edward so unaware that he fled to York, leaving many precious items behind.[note 1][3][5][6] In the late 12th century the abbey had a complement of 36 monks and 100 lay brothers, but by the time of the dissolution in November 1538, the abbey was host only to 25 monks and an abbot.[7] In 1539, its site was granted to Sir William Pickering.[8] The site is now maintained by English Heritage[9] and is scheduled as an ancient monument by Historic England with grade I listed status.[10][11] In October 2017, the west frontage of the church, including the famed Rose Window, underwent extensive conservation work to repair water damage and to repoint the stone walls.[12] Burials Mabel de Clare, d. 1204 (daughter of Roger de Clare, 2nd Earl of Hertford), wife of Nigel de Mowbray Roger de Mowbray (Lord of Montbray) (though some uncertainty about his final resting place) William de Mowbray, 6th Baron of Thirsk, 4th Baron Mowbray Joan of Lancaster, third daughter of Henry, 3rd Earl of Lancaster **************** NOTE: The new monastery was overseen by Abbot Roger, a capable administrator who successfully built up the economy of the abbey. Grants came from various benefactors, but principally from Roger de Mowbray, who was regarded as Byland’s founder. The Mowbrays continued to be the main patrons of the abbey into the 14th century. In the 15th century the monks of Byland believed that a monument in their chapter house was the tomb of Roger de Mowbray, although de Mowbray had died and was buried in the Holy Land in 1188. In 1893 Byland was sold to the Newburgh estate, which still owns the site. By this time, what was left of the crossing tower, church and monastic buildings had either been slighted when the abbey was suppressed, or had collapsed subsequently through neglect.

   Note: William de Mowbray, 6th Baron of Thirsk, 4th Baron Mowbray (c. 1173–c. 1224) was a Norman Lord and English noble who was one of the twenty-five executors of Magna Carta. He was described as being as small as a dwarf but very generous and valiant.[1] Family and early life William was the eldest of the one daughter and three or four sons of Nigel de Mowbray, by Mabel, thought to be daughter of William de Patri, and grandson of Roger de Mowbray.[2] Career under Richard I Mowbray appears to have been in the company of Richard I in Speyer, Germany, on 20 November 1193 during Richard's period of captivity on his return from Palestine.[3][self-published source?] In 1194 he had livery of his lands, paying a relief of £100. He was immediately called upon to pay a sum nearly as large as his share of the scutage levied towards Richard's ransom, for the payment of which he was one of the hostages.[4] William was later a witness to Richard's treaty with Baldwin of Flanders in 1197.[3][self-published source?] Career under John In 1215 Mowbray was prominent with other north-country barons in opposing King John. He was appointed one of the twenty-five executors of Magna Carta, and as such was specially named among those excommunicated by Pope Innocent III. His youngest brother, Roger, has sometimes been reckoned as one of the twenty-five, apparently by confusion with, or as a substitute for, Roger de Mumbezon. Roger died without heirs about 1218, and William received his lands.[4][5] Career under Henry III In the First Barons' War, Mowbray supported Louis. Mowbray was taken prisoner in the Battle of Lincoln (1217), and his estates bestowed upon William Marshal the younger; but he redeemed them by the surrender of the lordship of Bensted in Surrey to Hubert de Burgh, before the general restoration in September of that year.[4] In January 1221, Mowbray assisted Hubert in driving his former co-executor, William of Aumâle, from his last stronghold at Bytham in Lincolnshire.[4] Benefactor, marriage and succession Mowbray founded the chapel of St. Nicholas, with a chantry, at Thirsk, and was a benefactor of his grandfather's foundations at Furness Abbey and Newburgh, where, on his death in Axholme about 1224, he was buried.[4][3][self-published source?] Mowbray married Avice, a daughter of William d'Aubigny, 3rd Earl of Arundel, of the elder branch of the d'Aubignys. By her he had two sons, Nigel and Roger. The Progenies Moubraiorum makes Nigel predecease his father, and Nicolas and Courthope accept this date; but Dugdale adduces documentary evidence showing that he had livery of his lands in 1223, and did not die (at Nantes) until 1228. As Nigel left no issue by his wife Mathilda or Maud, daughter of Roger de Camvile, he was succeeded as sixth baron Mowbray by his brother Roger II, who only came of age in 1240, and died in 1266. This Roger's son, Roger III, was seventh baron (1266–1298) and father of John I de Mowbray, eighth baron.[4]

    Note: MOWBRAY, WILLIAM de, fourth Baron Mowbray (d. 1222?), one of the executors of Magna Charta, was the eldest of four sons of Nigel de Mowbray, by Mabel, daughter of Edmund (Roger?), earl of Clare, and grandson of Roger de Mowbray, second baron [q . v.] (Dugdale, Monast. Angl. vi. 320). He had livery of his lands in 1194 on payment of a relief of one hundred pounds, and was immediately called upon to pay a similar sum as his share of the scutage levied towards King Richard's ransom, for the payment of which he was one of the pledges (Dugdale, Baronage, i. 124). He was a witness to the treaty with Flanders in 1197 (Fœdera, i. 67; Stapleton, Rotuli Scaccarii Normanniæ, ii. lxxiv). When Richard I died, and John delayed to claim his crown, Mowbray was one of the barons who seized the opportunity to fortify their castles; but, like the rest, was induced to swear fealty to John by the promises which Archbishop Hubert Walter, the justiciar Geoffrey Fitz-Peter, and William Marshall made in his name (Hoveden iv. 88). Apparently it was thought prudent to exempt him from the scutage which was raised early in 1200 (Dugdale, Baronage, i. 124). When William de Stuteville renewed the old claim of his house to the Frontebœuf lands in the possession of the Mowbrays, thus ignoring the compromise made by his father with Roger de Mowbray [q. v.], and Mowbray supported his suit by a present of three thousand marks to the king, John and his great council dictated a new compromise. Stuteville had to accept nine knights' fees and a rent of 12l. in full satisfaction of his claims, and the adversaries were reconciled at a country house of the Bishop of Lincoln at Louth on 21 Jan. 1201 (Hoveden, iv. 117-18; Rotuli Curiæ Regis, ed. Palgrave, ii. 231). In 1215 Mowbray was prominent among the opponents of John. With other north-country barons, he appeared in arms at Stamford in the last days of April. When the Great Charter had been wrung from the king, he was appointed one of the twenty-five executors, and as such was specially named among those excommunicated by Pope Innocent. The castle of York was entrusted to his care (Dugdale, Baronage, i. 124). Mowbray's youngest brother, Roger, has sometimes been reckoned as one of the twenty-five, apparently by confusion with Roger de Mumbezon (ib. p. 618; Nicolas, Historic Peerage, ed. Courthope, p. 340). Roger died without heirs about 1218, and Mowbray received his lands (Dugdale, i. 125). Mowbray was taken prisoner in the battle of Lincoln in 1217, and his estates bestowed upon William Marshal the younger; but he redeemed them by the surrender of the lordship of Bensted in Surrey to Hubert de Burgh, before the general restoration in September of that year (Matthew Paris, iii. 22; Dugdale Baronage, i. 124, and Monast. Angl. v. 346; Royal Letters of the Reign of Henry III. i. 524). Three years later, in January 1221, Mowbray assisted Hubert in driving his former colleague as one of the twenty-five executors, William of Aumâle, from his last stronghold at Biham (Bytham) in Lincolnshire (Dugdale, Baronage, l.c.; Stubbs, Const. Hist. ii. 33). Mowbray founded the chapel of St. Nicholas, with a chantry, at Thirsk, and was a benefactor of his grandfather's foundation at Newburgh, where, on his death in Axholme about 1222, he was buried (Dugdale, Monast. Angl. vi. 320). He is said, in the sixteenth-century recension of the ‘Progenies Moubraiorum’ (ib.}, to have married Agnes, a daughter of the (second ?) Earl of Arundel, of the elder branch of the Albinis. By her he had two sons, Nigel and Roger. The ‘Progenies’ (Monasticon, v. 346, vi. 320) makes Nigel predecease his father, and Nicolas and Courthope accept this date; but Dugdale (Baronage, i. 125) adduces documentary evidence showing that he had livery of his lands in 1223, and did not die (at Nantes) until 1228. As Nigel left no issue by his wife Mathilda or Maud, daughter of Roger de Camvile, he was succeeded as sixth baron by his brother Roger II, who only came of age in 1240, and died in 1266 (ib. pp. 125, 628). This Roger's son, Roger III, was seventh baron (1266-1298) and father of John I de Mowbray, eighth baron [q.v.]
