a. He had succeeded his brother, Robert, by spring of 1141, when the Empress Maud, at Winchester, gave him a charter for a market every Sunday at his castle of Beaudesert. He attested several charters of Roger, and one of William, Earls of Warwick, and also attested the agreement made at Devizes in 1153 between Henry, Duke of Normandy (later Henry II) and Ranulph, Earl of Chester. He held land in Rutland, as well as land under three tenants-in-chief, namely Beaudesert and Henley in Arden. After his brother's death, he confirmed the grant of Wing to Thorney Abbey for the souls of himself, his wife, and children, and "especially of his brother Robert", and made a gift to Guisborough for the soul of his brother Henry. He married Juliane, the daughter and coheir of Geoffrey Murdac.

b. With his brother's widow, Alice de Harcourt, he joined in making a grant of Charlcote which was confirmed by Richard I and John, and he gave land in Beaudesert to Reinbald de Charlecote, the mill of Henley in Arden to the monks of Conches (for the souls of his father Thurstan, and mother Juliane), and land and the mill of Beaudesert to his younger son, Thurstan. He was deceased by the spring of 1199, when his heir was in the custody of the King's hand. The name of his wife is not known.

c. He was still a minor when he succeeded his father in or before 1199, and in 1205, the King took his homage and gave him his land. In the summer of the following year he was abroad in the King's service, and in 1210, he was in the King's service in Ireland. He appears to have joined the rebellion against John. He died before 21 Nov and possibly before 23 Jul, 1216. CP states that the identity of his wife is not known.

d. As noted in note (c) above, Complete Peerage states that the identity of Thurstan de Montfort's wife is not known. But, John Ravilious, posting on soc.genealogy.medieval, has offered that Thurstan's wife was likely a daughter of William I de Cauntelo/Cantelou, and cites the writings of Adam Marsh, in the 1250s, in which he states Piers de Montfort and (Walter) Cantelou were "closely tied into Simon's (de Montfort) affinity." Additionally, he cites a footnote entry in Complete Peerage, sub Montfort, in which Piers de Montfort wrote to Walter de Merton, Chancellor, about the business of Lord (Bishop) of Worcester (Walter de Cauntelo), calling him "avunculi nostri", i.e., "my uncle".

e. A minor at his father's death, his wardship and marriage was granted by King John to William de Cauntelo. He was still under age in Oct 1231. He went on pilgrimage to Santiago with his lord, William de Cauntelo, in 1236, and in 1242 was with the King in the unsuccessful expedition to Poitou. In 1245, his lands, which had been taken into the King's hand because he had attended a prohibited tournament, were restored to him. In autumn of 1248, he went overseas with Simon de Montfort, who had just been appointed Seneschal of Gascony, and presumably returned to England in 1250 or early 1251, when he had custody of the castle of Harestan. For the next two years he was in Gascony, and on 22 Apr 1254 was appointed one of the guardians of the truce in France. In Sep 1257, he was appointed to guard the March of Wales in Montgomery, and to keep the counties of Salop and Stafford, with the castles of Shrewsbury and Bridgnorth. In May of 1258, he received a grant of Ellesmere Castle for 18 years. He was one of the 12 magnates elected by the Barons to represent them on Council of 24, which was forced upon the King in the "Mad" Parliament at Oxford in Jun 1258. The following Jun he was one of the commissioners sent to the Lord Montgomery to treat with Llewelyn on breaches of peace, a truce being made in Jul. In 1261, the King renewed his struggle with the Barons, and they elected Piers one of the three arbitrators to negotiate with the King. At this point, Piers had begun to associate himself with the Baronial party, and in Apr 1262, the sheriff of Warwickshire had orders to prevent the fortification of Piers' castle of Beaudesert. When peace was made, temporarily in Jul 1263, he was appointed keeper of the castles of Corfe and Shirburn, and in Sep he accompanied the King on his brief visit to France. But war was renewed and he and his two sons were with Simon de Montfort, the younger, when the Keeper of Northampton Castle surrendered it, and two days later, when the King took the castle, Piers and his two sons were taken prisoners. Removed to Windsor Castle, they were released after the battle of Lewes. During the dominance of Simon de Montfort, Piers received many commissions and grants. In Jul the King requested that Piers bring him the terms proposed by the Barons, and on 11 Sep Piers was one of the envoys appointed to treat concerning the reformation of the state of England. He accompanied Simon de Montfort through Monmouthshire into Wales, and during this time was keeper of the royal seal. He was slain at the battle of Evesham 4 Aug, his sons Piers and Robert being wounded and taken prisoners. His wife Alice survived him.

f. Having been taken prisoner, along with his father and brother, in Apr 1264, and then at Evesham having been wounded and again taken prisoner, he appears to have appeased the King's rancor, for on 28 Jun 1267, he was pardoned for all trespasses and recovered part of his father's lands. In 1268 he gave the advowson of Ponteland, Northumberland, to his friend Walter de Merton for his newly founded college at Oxford. In Feb 1271/72, he had protection for going on pilgrimage to Santiago, and went again in Jan 1274/75. In Nov 1276 he was one of the magnates at a Council at Westminster concerned with Llewlelyn and Welsh affairs, and the following Feb was going to Wales in the King's service. He gave the manor of Greetham to the Bishop of Durham for a hospital for the sick and poor. In 1280 he granted to Queen Eleanor the marriage of his eldest son, John. He married Maud, daughter and heir of Matthew, son of Henry de la Mare, with whom he had Ashtead in Surrey.

g. He appears to have been of age in 1284/85. On 13 Apr 1294, he was going beyond seas by the King's command with Eleanor, Countess of Bar, the King's daughter, and in Aug, William and John de Montfort were in the Earl of Lincoln's company in Gascony. He was summoned to Parliament 24 Jun 1295, whereby he is held to have become Lord Montfort. He married Alice, daughter of William de la Plaunche, between 1286 and 1289. She survived him.
