PONCE de Traves (-15 Apr after 1156). Her parentage is confirmed by the charter dated 28 Oct 1157 under which [her sons] "comes Stephanus...et fratrem meum comitem Gerardum" settled disputes with Charlieu abbey, with the consent of "matris nostræ...comitis Willelmi patris nostri et avi nostri domini Theobaldi de Treva"[375]. The Chronicle of Alberic de Trois-Fontaines names "Aleyde comitissa qui fuit unica heres de Treva, relicta Theobaldi de Rogemont" as wife of "comitem Guilelmum"[376]. Bouchard points out that Thibaut de Rougemont was still alive when Comte Guillaume is alleged to have married Ponce de Traves and suggests that the chronicle confused her with her mother[377]. It is more likely that Alberic confused Ponce with her sister Alix. "Willelmus Masticonensis comes et Burgundie" donated "abbatiam de Balma" to Cluny by charter dated 14 Jun 1147, confirmed by "Poncia comitissa uxore mea et filiis meis Stephano et Gerardo"[378]. m GUILLAUME [III] Comte de Mâcon, son of ETIENNE [I] "Tête-Hardi" Comte de Mâcon [Bourgogne-Comté] & his wife Beatrix of Lotharingia (before 1102-27 Sep 1155).
