GEOFFROY [II] de Gâtinais, son of HUGUES du Perche Comte de Gâtinais & his wife Beatrix de Mâcon (-30 Apr [1043/45]). His parentage is confirmed by the charter dated 26 May 1028 under which Francon Bishop of Paris agreed with "Albericum illius supradicti Gosfredi filium et heredum", concerning a prior grant by the bishop's predecessor to "Gosfrido comiti Landonensi castri", with the approval of "fratribus ipsius Alberici, filiis Hugonis Pertice…Gosfredo et Letoldo"[215]. A genealogy presented by Foulques IV "le Réchin" Comte d'Anjou to the bishop of Angers in [1085], justifying the annulment of his fourth marriage with the daughter of Gauthier Comte de Brienne, lists "ex Letaldo, Albericus natus est, ex Alberico, Beatrix, ex Beatrice, Gosfredus de Castello Landonensi, ex Gaufrido, Gaufridus et Fulco presens"[216]. He succeeded his half-brother as Comte de Gâtinais, Seigneur de Château-Landon. The fact that Aubry Comte de Gâtinais and Geoffroy [II] Comte de Gâtinais were two different individuals, the inevitable conclusion from the two sources cited, is somewhat clouded by the Historia Comitum Andegavorum which records that "Gaufridus Martellus…nepotibus suis" were "filiis Adhelæ sororis suæ et Alberici comitis de Gastinais"[217], and by the Chronicle of Saint-Maxence which names "Alberici Contracti comitis de Gastina" as father of "Goffredus et Fulco Rechin"[218].
m ([1035]) as her first husband, ERMENGARDE d'Anjou, daughter of FOULQUES III "Nerra" Comte d'Anjou & his second wife Hildegard [de Metz] ([1018]-murdered church of Fleury-sur-Ouche, Côte d'Or 18 Mar 1076, bur Abbaye de Saint-Seine, Côte d'Or). The Historiæ Andegavensis names "Goffridi de Castro Landono et Ermengardis filia Fulconis Comitis Andegavensis" as parents of "Fulco comes Andegavensis"[219]. She married secondly ([1048]) Robert I "le Vieux" Duke of Burgundy. Her second marriage is deduced from a genealogy of the Comtes d'Anjou which names "Fulco (pater) Gosfridus et Ermengardis (mater) Gosfridus (et) Fulco (et) Hildegardis, de altero patre, filia Roberti ducis fratris Henrici regis"[220]. The necrology of Molesme records the death "XV Kal Apr" of "Robertus dux Burgundie et Ermengardis uxor eius"[221]. She was murdered with her second husband.
Comte Geoffroy & his wife had three children
