The barony fell into abeyance among his granddaughters and coheirs, Joan and Eleanor, at his death on 16 February 1364. At the death of Joan without issue, Eleanor became, according to modern doctrine, "de jure" Baroness Maltravers. The barony later became a subsidiary title of the Earl of Arundel and subsequently the Duke of Norfolk.
