GUILLAUME de Say . The Complete Peerage refers to this Guillaume de Say but does not establish his relationship with the later Say family (Barony created by writ in 1313, see UNTITLED ENGLISH NOBILITY)[1124]. Such a connection is likely given the unique name (according to The Complete Peerage, there is only one place of this name in Normandy about 2 miles south-east of Argentan[1125]). m AGNES de Grantmesnil, daughter of HUGUES de Grantmesnil & his wife --- (-14 Sep ----). Orderic Vitalis names “Adelinam et Hadvisam, Rochesiam et Mathildem et Agnetem” as the daughters of “Hugo de Grentemaisnilio” and his wife “Adelidem filiam Ivonis comitis de Bellomonte”, adding that Agnes married “Guillelmo de Saia”[1126]. The necrology of the monastery of Ouche records the death "14 Sep" of "Agnes filia Hugonis de Grentesmesnil"[1127].
