"Ermengars" sold land in Colonicas (pago Matisconense), with her husband "Gillevertus", by charter dated May 926. According to Du Chesne in 1625, she was Ermengarde, daughter of Richard "le Justicier" Duke of Burgundy. More recently this affiliation has been challenged, in particular because she is not mentioned in her supposed mother's will. In addition, if it is correct that Giselbert's mother was the daughter of King Boso, she would have been her husband's first cousin, which seems unlikely to have been accepted by the church. "Gislebertus…comes Heduensis" granted property to "suo fidele Guitbaldus…nec non eius coniuge Rutrudis" by charter dated 11 Dec 934, signed by "Gisleberti comitis, Ermengardi, Adaledis filiam eorum…". 1
Ermengarde married Duc Giselbert DE BOURGOGNE, Comte d'Autun, son of Cte Manassès II DE VERGY et de Dijon and [Ermengarde] DE PROVENCE, about 913. (Giselbert DE BOURGOGNE was born in Châlons-Sur-Marne, Marne, Champagne, France and died on 8 Apr 956 in Auxerre, Yonne, Bourgogne, France.)
