4. [--- de Chalon (-before 1018). This possible origin of the mother of Othon [II] Comte de Mâcon is deduced from the undated charter under which "domnus Hugo comes Cabilonensium" donated property "in pago Augustudunensi in villa Martiniacensi" to Paray-le-Monial which is subscribed by "Ottonis nepotis eius, Teudbaldi nepotis eius, Maltidis sororis eius"[495]. The same relationship is stated in the charter dated 1018 under which "Vualterius Æduorum presul" donated property to the abbey of Flavigny subscribed by "Landricus comes, Otto comes nepos Hugonis episcopi, Tetbaldus comes nepos ipsius episcopi"[496], and in the charter dated 1020 under which "Wido clericus" donated property "in pago Cabillonense" to Cluny, subscribed by "Ugo comes et episcopus et nepos eius Otto comes…"[497]. One explanation is that "Otto comes" in these three charters was the same person as Othon-Guillaume Comte de Mâcon, and that he was nepos of Hugues Comte de Chalon because his mother Gerberge was Hugues's older half-sister. However, as shown above, the theory about Gerberge's Chalon origin is far from certain. Another possibility is therefore that the three charters refer to Othon [II] Comte de Mâcon, grandson of Othon-Guillaume, the identity of whose mother has been the subject of much speculation. If this second possibility is correct, this unnamed daughter presumably died before her sister Mathilde as she did not subscribe the 1018 charter.
