In the seventh year of king Raoul (929/930), Fulco (Foulques), his wife Roscilla, and his sons Widdo (Gui) and Fulco, gave a donation to Saint-Aubin d'Angers for the benefit of his soul and the souls of his father (genitor) Ingelgerius, his son Ingelgerius, his father-in-law Warnerius and the latter's wife Tescenda ["Ego Fulco, Andecavorum comes, abbas quoque Sancti Albini Sanctique Lizinii, necnon et uxor mea Roscilla et filii mei, Widdo ac Fulco, nullius cogentis imperium, sed nostra plenissima voluntate, fatetur nos, pro Dei amore et pro remedium mee anime vel anime Ingelgario, genitor meo, atque Ingelgerio, filio meo, necnon pro anima Warnerio, socro meo et uxore sua, Tescenda].

Although the charter confirms that the father of Foulques was named Ingelger, contemporary records tell us nothing about his mother. Some later sources attempt to define his wife. A history of the counts of Anjou compiled in the twelfth century, Gesta Consulum Andegavorum records that Ingelger married ["Landonensis castri sive Gastinensis pagi consul nomine Gaufredus…filiam unicam…Adelam"]. The Historia Comitum Andegavorum records that Ingelgerius married ["Rursus Adelardus et Raymo ambo germani fratres, Turonensium et Andegavensium pontifices, neptem suam Aelindis"].
