THIBAUT [II] de Blois, son of THIBAUT [I] "l'Ancien" Vicomte de Tours & his first wife --- ([910]-16 Jan [975/77]). "Le comte Thibault père de Thibault" relinquished rights relating to "les terres de Vancé, de Joué, de Martigny et de Berthenay" to Tours Saint-Martin and paid for his future burial in the abbey by charter dated to [944][35]. "Ledgardis comitissa necnon Hugo episcopus et filius meus et item filius meus Odo comes" donated property to Saint-Martin de Tours, for the souls of "Theobaldi comitis quondam senioris mei…Richildis quondam sanctimonialis, eiusque filii Richardi episcopi" (referring to "dicti comitis et fratris sui Theobaldi", in relation to Bishop Richard), by charter dated to [980][36]. This confirms that Richildis was the mother of Richard and that Richard was the brother of Thibaut. However, the absence of a phrase in the text such as "matris sui" linking "Richildis" to "Theobaldi comitis" suggests that she was his mother and that therefore the brothers were born from different marriages of the same father. He succeeded [his father] in [944] as THIBAUT I "le Tricheur" Comte de Blois, Vicomte de Tours. He dominated Brittany as guardian of his nephew Drogo, after the death of his brother-in-law Alain II Duke of Brittany in 952[37]. The Gesta Normannorum records that he plotted against Richard I Comte [de Normandie], who defeated Thibaut´s forces in [955] after the French captured Evreux[38]. "Domnus Tetbaldus comes Turonis" withdrew his claims to a serf in favour of the monks of Saint-Martin de Tours by charter dated 957, signed by "domni Tetbaldi comitis, Tetbaldi filii ipsius…Alberici Aurelianensium vicecomitis…"[39]. "Teutbaldi comitis, Teutbaldi junioris, Gausfredi comitis, Hugonis comitis Cenomannorum…" subscribed the charter dated Sep 960 under which "Aremburgis" donated property to Saint-Florent de Saumur[40]. He gained control of the counties of Chartres and Châteaudun in [960], and became the vassal of Lothaire King of the West Franks in 963. He was excommunicated by Odalric Archbishop of Reims in 964 for taking Coucy and other estates from the archbishopric[41]. Seigneur de Chino, de Saumur et de Baugency.

Rodulfus Glauber refers to the wife of Comte Guillaume as "sororem [Heribertum Trecorum comitem]", specifying that she was childless by her first husband, when recording her second marriage to "Tetbaldus"[43]. The Liber Modernorum Regum Francorum refers to the wife of "Tetbaudi comitis" as "sorore Herberti Trecorum comitis"[44]. "Theobaldi comitis…Ledgardis comitisse" subscribed the charter dated 950 under which Ragnfred Bishop of Chartres donated property to Chartres Saint-Père, although the relationship between the two is not specified[45]. "Ledgardis" donated property to "Sancti Petri Carnotensis ecclesiam", for the souls of "senioris mei…comitis Tedbaldi…patris mei Heirberti, Trecassini comitis", with the consent of "archipresule…Hugone et…comite Odone, filiis meis", by charter dated 5 Feb 978, signed by "…Emma comitissa Pictavæ urbis…"[46].

"Hugonis ducis, Odonis comitis, Hugonis sanctæ Bituricensis archipræsulis, Letgardis comitissæ, Bertæ comitissæ, Gauzfridi vicecomitis…" subscribed the charter dated 985 under which "Robertus" donated property to "Sancti Petri Carnotensis", on the advice of "Odonem, simul cum sua matre Ledgarde, pariterque dominam meam Bertam, ipsius æque coniugem"[48].
