   General Notes:

"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…filiis autem Theoderici atque sue uxoris Hermentrudis, Lodewico, Wilelmo, Hugone"[78]. The Chronicle of Alberic de Trois-Fontaines names "Theodericus" as brother of "Raynaldum…comes Barri et Montionis" specifying that Thierry was expelled in 1113 and retained only the county of Montbéliard[79].
