Anselm was his brother’s heir, but he apparently died before he was ever invested with the lands, titles and offices of his brother Walter. He married Maud, daughter of Humphrey de Bohun, second earl of Hereford, but they had no children. Anselm died December 23, 1245 at Striguil, but there are no records of how he died. Anselm and his brother Walter were buried near their mother, Isabel, at Tintern in Monmouthshire.
