(d 1066?) was the daughter of William I. The continuator of William of Jumièges (lib. viii. cap. 34) states that Adelidis, a daughter of William I, was betrothed to (King) Harold, and remained single after his death. Orderic (573 c.) states that she took the veil, but makes her sister Agatha the betrothed of Harold. William of Malmesbury mentions that one of William's daughters was betrothed to Harold, but makes him speak of her to William as dead in 1066 (Gest. Reg.
lib. iii. c. 238). Mr. Planché asserts (but gives no authority) that she was born in 1055, was betrothed to Harold in 1062, and was dead by 1066.
