Simon (fl. 1162×1163) was a twelfth-century Anglo-Norman.
Uncertain parentage
Simon may have been a son of Avelina de Hesdin and her second husband, Robert fitz Walter.[1] As such, Simon seems to have been a uterine brother of Avelina's sons by her earlier marriage to Alan fitz Flaald: Jordan fitz Alan (fl. 1128–1130), William fitz Alan (died 1160), and Walter fitz Alan (died 1177).[2]
Simon is recorded to have witnessed a grant of Walter to Paisley Priory.[3] The fact that he appears at the bottom of the listed witnesses, and is described as a brother of Walter, could indicate that the men were uterine brothers.[4]
Simon is also recorded to have issued a confirmation of a grant by Alan and his mother concerning the latter's lands of Kempston, Sporle, and Newton.[5]
Simon is sometimes alleged to have been a son of Avelina and Alan,[6] and to have been an ancestor of the Boyd family.[7]
