The Liber Modernorum Regum Francorum names "Tetbaudus et Stephanus" as the two sons of Comte Eudes, specifying that Thibaut succeeded in "Carnotensem et Turonensem". The Chronicle of Alberic de Trois-Fontaines names "Theobaldi filii Odonis Campaniensis" when recording that he lost Tours in 1041. "Odo comes filius [Odonis comitis]" confirmed a donation of his father by charter dated to [1032/37], subscribed by "Tetbaldi filii eius, matris eius Ermengardis…Hervei vicecomitis".
He succeeded his father in 1037 as THIBAUT III Comte de Blois, de Chartres, de Châteaudun, de Meaux, de Sancerre et de Troyes. He lost Beauvais some time after 1037. Guillaume de Jumièges records that "comitem Tetbaldum" was captured by Geoffroy Comte d'Anjou who extorted the town of Tours from him by force. The Chronica Rainaldi records that "Tetbaldus, filius Odonis comitis" was captured by "Goffrido comite Andecavorum" in 1044 after which the city of Tours surrendered. Comte de Bar-sur-Aube, presumably after 1077, maybe de iure uxoris.
The necrology of Saint-Père-en-Vallée records the death "II Kal Oct" of "Tebaldus comes Carnotensium". The Chronicle of Alberic de Trois-Fontaines records that "comes Theobaldus [filius Odonis]" was buried "apud Spernacum". 1
Thibault married Gersende DU MAINE, daughter of Herbert I "Eveille-Chien" DU MAINE. (Gersende DU MAINE was born between 1025 and 1035.)
Thibault also married Alix DE CRÉPY, comtesse de Bar-sur-Aube, daughter of Cte Raoul III "Le Grand" DE VEXIN, comte de Valois et Vexin, and Ctse Adèle DE BAR-SUR-AUBE, before 1061.)
