Cantilupe, William delocked

(d. 1254)
  • Robert C. Stacey

Cantilupe, William de (d. 1254), baron, was the son of William (II) de Cantilupe (d. 1251), steward to Henry III. In 1238 William (II) acquired the wardship and marriage of Eva, one of the coheirs of William (V) de Briouze (d. 1230), and by July 1241 Eva and William (III) were married. The Cantilupe family lands lay at Eaton Bray, Bedfordshire, and at Aston Cantlow, Warwickshire. By his marriage, however, William (III) became lord of Abergavenny and an important marcher baron; after 1245 he and his wife acquired additional lands in the marches and in the south-west through the inheritance of Eva's mother, Eva Marshal, one of the coheirs to the Marshal earldom of Pembroke.

His wife's inheritance brought Cantilupe into fierce conflict with John of Monmouth between 1248 and 1253 over Penrhos Castle, a conflict that may lie behind Matthew Paris's story, otherwise uncorroborated, that the king treated Cantilupe harshly in 1251 on his succession to his father's estates. Otherwise his relations with the king were consistently good. He served on Henry's military expedition of 1242–3 to Gascony, and from January 1243 received an annual fee of £50 at the exchequer. He also received frequent gifts of deer and timber from the royal forests. In 1253–4 he served again with the king in Gascony, emerging as one of the king's most important courtiers. He was still with the king in mid-July 1254, but must have returned to England soon afterwards, perhaps in ill health. He died on 25 September 1254 and was buried at Studley Priory, Warwickshire, where his grandfather, William (I), was also buried. Simon de Montfort, earl of Leicester, a distant relative who had served with him in Gascony, and Humphrey (V) de Bohun, earl of Hereford and the husband of Eva's sister Eleanor, laid his body in the grave. Like others of his family, Cantilupe was devoted to the crusade, and left a substantial sum of money in his will to redeem his own unfulfilled crusading vow. This money eventually went to William de Valence, the king's half-brother, to forward his own crusading intentions.

Eva de Cantilupe died around 20 July 1255. Of their three children, Sir George de Cantilupe died childless in 1273, soon after he came of age. His inheritance then passed to his two elder sisters: Joanna (d. 1271), who married Henry Hastings (d. 1269), and whose son John inherited Abergavenny; and Millicent (d. 1299), who married first John de Montalt and second Eudo de la Zouche (d. 1279), and whose son William Zouche (d. 1352) eventually inherited Eaton Bray.
