William III de Cantilupe
William III de Cantilupe (died 25 September 1254) (anciently Cantelow, Cantelou, Canteloupe, etc, Latinised to de Cantilupo) was jure uxoris Lord of Abergavenny, in right of his wife Eva de Braose, heiress of the de Braose dynasty of Welsh Marcher Lords. His chief residences were at Calne in Wiltshire and Aston Cantlow (named after his family), in Warwickshire, until he inherited Abergavenny Castle and the other estates of that lordship.
Marriage & progeny
At some time before 15 February 1248 he married Eva de Braose, daughter and heiress of William de Braose (d.1230) by his wife Eva Marshal, daughter of William Marshall, 1st Earl of Pembroke. By his wife he had progeny including:
- George de Cantilupe (died 1273), Lord of Abergavenny, only son and heir, who died without progeny, leaving his sisters or their issue as his co-heiresses.
- Milicent de Cantilupe (d.1299), who married twice, firstly to Eudo la Zouche and secondly to John de Montalt
- Joan de Cantilupe (d.1271), who married Henry de Hastings (c.1235-1269).
He died "in the flower of his youth" in 1254. Simon de Montfort, a close friend of the family, was one of the chief mourners at his funeral.
