Il est marié avec Richilde Nn.
Ils se sont mariés
Enfant(s):
[FASTRE [II] d'Oisy (-after 1111). The Liber de Restauratione Sancti Martini Tornacensis names "Fastridus filius eius [=Fastredus]", and in a later passage specifies that he was "filius illius Ide" and "advocatus Tornacensis"[760]. Another perspective on the parents of Gauthier [I] d’Oisy is provided by the late 13th century genealogy by Balduinus de Avennis which records that "nepos suus ex sorore Walterus cognomina Plukellus" succeeded "Goswinus de Oysiaco, castellanus Cameracensis"[761]. It is not known which version might be correct. Avoué of Tournai.]
m RICHILDE, daughter of ---. The Liber de Restauratione Sancti Martini Tornacensis names "Richilde" as wife of "Fastradus", without giving her origin, specifying that she became a nun at Tournai after her husband's death[762]. Her family origin has not been traced. However, the [1205] Chronicle of Liessies abbey records that Baudouin IV Comte de Hainaut was guardian of “trois Gillion, enfants nobles, dont les pères étaient morts...de Chimay...de Bousignies [Bouchain] et...de Trazegnies”, noting that the last named was claimed by “Gautier d’Avesnes avec lequel il était plus proche parent qu’avec le comte”[763]. The precise family relationship between Gilles [I] de Trazegnies and Gauthier [I] d’Oisy Seigneur d’Avesnes has not been ascertained: maybe it was through Gauthier’s mother.]
Fastre [II] & his wife had three children:
GAUTHIER [I] d'Oisy (-1147)
