Medilands (Jun 2021) Burgundy Kingdom: Counts of Burgundy Ermentrude de Bourgogne

1. ERMENTRUDE de Bourgogne ([1050/55]-1106 or after, bur Autun Cathedral). Her birth date is estimated from her possible marriage date, bearing in mind the probable dates of birth of her oldest children. If it correct, it is likely that Ermentrude was one of her parents’ oldest children. "Filia Wilelmi comitis de Burgundia Hermentrudis et filii sui Fridericus, Raginaudus, Theodericus" founded the Cluniac abbey of Froidefontaine by charter dated 8 Mar 1105 in which she names "suis antecessoribus…Lodewico, Sophia eius uxore, et filiis eorum Brunone, Theoderico, Lodewico, Friderico, filiabus vero Mathilde, Sophia, Beatrice, filiis autem Theoderici atque sue uxoris Hermentrudis, Lodewico, Wilelmo, Hugone", witnessed by "Henricus de Suarca cum genero suo Gerunch, Gotefridus filius avunculi eiusdem comitis [Friderici]"[45]. The Chronicle of Alberic de Trois-Fontaines names "Ermentrudem" as wife of "Theodericum [filius comiti Montionis Ludovico]" specifying that she was heiress to Montbéliard[46]. She retired to the château de Montbéliard after the death of her husband. She subscribed a sale act of her son Renaud in 1106[47].
