1. GUILLAUME de Bourgogne (-12 Nov 1087, bur Besançon)
2. GUY de Bourgogne (-after 1069)
3. HUGUES de Bourgogne (-after 1045)
4. FOULQUES de Bourgogne . “Willelmus Burgundiæ comes” donated property to Besançon cathedral, for the souls of “mea...necnon...Fulchonis fratris mei et Ottonis filii mei”, by undated charter[30]. Bouchard suggests that he was the same person as "Foulques de Joux"[31], who is named in the Miraculis S. Mariæ Laudunensis as "nobilissimus princeps in Burgundia…Falco de Jur, vel de Serrata" when recording his marriage, in its recital of the ancestry of Barthélemy Bishop of Laon[32]. However, according to Europäische Stammtafeln, the husband of Aelis de Ramerupt was Conon "Falcon" de La Sarraz [Grandson], whose death is estimated to "before 1114". If Conon died soon before that date, it is unlikely that Bouchard’s suggestion could be correct.
