- Born: 1076-1078

"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". 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.
Thierry married Gertrude VON HABSBURG, daughter of Gf. Otto II VON HABSBURG and Hilla VON PFIRT. (Gertrude VON HABSBURG was born about 1092 in Habsburg, Aargau, Schweiz.)
