  Research Notes:

The Chronicle of Alberic de Trois-Fontaines names "Ermentrudem" as wife of "Theodericum [filius comiti Montionis Ludovico]" specifying that she was heiress to Montbéliard. "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]". It is assumed from the expression "suis antecessoribus" that all those so described were deceased at the date of the foundation. She subscribed her son Renaud's act of sale of the fortress of Commercy to the abbé de Saint-Mihiel in 1106. 2
