Comte Guy & his [first] wife had one child:
1. ANNE de Ponthieu (-[after 1067]). "Pontivensium comes Wido" donated property to Compiègne Saint-Corneille, confirmed by "Anne comitisse nostre filie", by charter dated to [1067 or after][1221]. The title "comitisse" in this charter suggests that Anne must have been married to a count at that date. [m ---.]
