Gossuin d'Oisy, seigneur d'Avesnes

FASTRE [I d'Oisy], son of --- (-<1092). Avoué de Tournai. The Liber de Restauratione Sancti Martini Tornacensis names "Fastredum eiusdem urbis advocatus" when recording his marriage[754].
m IDA d'Avesnes, daughter of WEDRICUS d'Avesnes & his wife ---. The Liber de Restauratione Sancti Martini Tornacensis names "Idam, germanam Theoderic de Asvensis" as wife of "Fastredus"[755].
Fastre [I] & his wife had [four] children:

1. GOSSUIN d'Oisy (-1127). The Liber de Restauratione Sancti Martini Tornacensis names "Gosceguinus, filius domine Ida", specifying that he succeeded "avunculo suo Teoderico"[756]. Seigneur d'Avesnes, de Condé et de Leuze. "Gossuini de Montibus, Gossuini de Avesnis, Widonis de Cervia, Hugonis de Lens" subscribed the charter dated 1117 under which Baudouin III Comte de Hainaut donated property to the monastery of Saint-Denis[757]. “...Gossuinus Avesnensis et frater eius Isembardus...” witnessed the charter dated 1117 under which Bouchard Bishop of Cambrai confirmed a donation made to the abbey of Saint-Denis near Mons[758]. A charter dated to [1145] records commitments by the abbot of Anchin to the inhabitants of Avesnes and names "Gozewinus Avesnensis castri dominus [et] uxore sua Agnete…Walterus successor et nepos suus [et] uxore sua Ida et filio suo Teoderico"[759]. The Chronicon Lætiense records the death of "dominus Gozvinus" and his burial "ante hostium basilice sancte Marie"[760]. m AGNES de Ribemont, daughter of ANSELME [II] de Ribemont & his wife Berthe ---. The Chronicle of Alberic de Trois-Fontaines names "Agnes" as daughter of "Anselmus de Ribodimonte", and names her son "Gossuino"[761]. The Liber de Restauratione Sancti Martini Tornacensis names "Agne…filia Anselmi de Ribotmont" as wife of "Gosceguinus, filius domine Ida", specifying that they were childless, that he appointed his nephew Gauthier as his successor, and that Agnes became a nun after her husband's death[762]. The late 13th century genealogy by Balduinus de Avennis records that "Agnetem…filiam Anselmi comitis de Ribodimonte" married "Goswinus de Oysiaco, castellanus Cameracensis" but was childless[763].
2. 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"[764]. 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"[765]. 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[766]. 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”[767]. 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.]
3. ISEMBARD (-after 1117). “...Gossuinus Avesnensis et frater eius Isembardus...” witnessed the charter dated 1117 under which Bouchard Bishop of Cambrai confirmed a donation made to the abbey of Saint-Denis near Mons[791].
4. daughter . The Annales Cameracenses refer to the wife of "Elbodo [filius Evrardi de Watterlos [et] coniuge sua Disdelde]" as "Gossuini de Avesnes sororem, materteram Galteri Puluchat"[792]. m ELBODO, son of EVRARD de Watterlos & his wife Disdelda ---.
