  The Lord Henry D'Oyly, 5th Baron of Hocknorton, being a minor at his father's death, was placed in wardship with all his barony to his maternal uncle Humphry de Bohun,[115] his nearest kinsman, who could not inherit his estates; but attained his majority before 1183, for in the 29 Hen. II. Robert de Whitfield, being High Sheriff of Oxfordshire, he confirmed by deed (styling himself Henry son of Henry D'Oyly) all the grants of his father and grandparents to Oseney Abbey, and adds a gift of his own; all which he did with the consent of Robert D'Oyly his brother, his free tenants, and friends; and lastly gives his body to be buried in Oseney Abbey at his death.[116] He is described as ''Constabularius Regis" in various charters, and in one so described confirms the grants of his ancestors to Eynsham Abbey.[117]—On the redemption of King Richard, in 1194, he paid 32l. 6s. 8d. scutage for his knight's fees; and, as soon as the monarch returned to England, was invested (no doubt in consequence of his kinsman's decease in the King's service in Austria) with the office of high sheriff of Oxfordshire, and held it, not only for the latter half of 1194, but in 1195, 6, 7, 8, 9; and stood in high favour with King Richard during the whole of his reign. He was not so fortunate, however, under his successor. In 10th John he accounted to the King for a debt of 1015l. 11s. 11d., which he owed to Simon the Jew of Oxford, but which had been seized into the King's hands.[118] In 1211-12 he is recorded to have held 32 knights and a third part; all which, however, were soon after confiscated to the crown, for he joined the rebellious barons, and in July 1215 was constituted a coadjutor[119] to the twenty-five appointed to enforce the observance of Magna Carta, then granted at Runnimede.—But on the King's restoration to power his Majesty seized on all D'Oyly's baronies, and in November 1215 conferred them on his favourite, Englard de Cygoni, and ordered the high sheriff of Berks and Oxfordshire to give Cygoni possession of them; commanding all D'Oyly's free tenants to render their service to him[120] Henry the Third soon succeeded, however, and, after employing his predecessor's policy as long as he dared, continuing[121] Cygoni in his ill-acquired possessions, restored the estates to D'Oyly in September 1217; and it is proved that in the following year Henry D'Oyly held, once more, his possessions in the counties of Oxford, Bucks, Northampton, Stafford, and Warwick.[122] In 9th Henry III. Henry D'Oyly impleaded William Bassett (son of John son of Osmund) for half a knight's fee in Ispeden, co. Oxon., and his pedigree is detailed in the suit.[123]
  
  In 1226, growing old, he turned his attention once more to the Church, and gave all his remaining interest in Weston Green manor to the monks of Oseney.[124] He died aged and s.p.s. in 1232 (17 Hen. III.) and was interred in the additions to Oseney Abbey, only a short time before completed;[125] while the great mass of his estates was inherited by his nephew and heir-general, Thomas de Newburgh, Earl of Warwick.— Henry D'Oyly, the last Baron of Hocknorton, was twice married, however: first to Sibilla . . . .; secondly, to Matilda, daughter and coheir of . . . ., whose sister was mother of that "Count Humphry Bohun" living in the latter part of Henry III's reign.[126] She survived D'Oyly, had Kidlington, co. Oxon. in dower, and subsequently became the second wife of William de Cantelupe, a loyal adherent of King Henry III, and also of his predecessor, a baron of distinction in Leicestershire, Worcestershire, and Herefordshire, and chief steward and one of the chief council to both those kings. He bore "Gules, three fleurs de lis, (afterwards changed to leopards' faces jessant de lis) or,"[127] died in 1238, issueless by D'Oyly's widow; but, by his former wife, ancestor of the Barons Cantilupe.[128] His second wife survived him, but died s.p, it seems, before 45 Hen. III. (1261,) for in that year King Henry confirmed Kidlington manor, which she had held in dower, to John de Plessetis,[129] on whom he had conferred the bulk of the D'Oylys' domains; while the manor of Gussich Dynaunt, co. Dorset, which the same king had conferred on herself, descended to her heir at law (her nephew ex parte sororis), the said Earl Humphry de Bohun,[130]—By Sibilla, his first wife, Henry D'Oyly, the last baron, had issue an only child,
