THIBAUT [Tetbald] [I] "l'Ancien"

son of --- (-[944], bur Tours Saint-Martin). [Comte de Chartres: Guillaume de Jumièges describes how "Tetboldus comes" threatened “Hastingus” into selling “Carnotenam urbem” to him, after which Hasting became a pilgrim and disappeared (“peregre profectus disparuit”)[27], maybe dated to [900], an earlier passage recording that Hasting held Chartres presumably from “Rainaldus totius Franciæ dux” who had sent him to negotiate unsuccessfully with Rollo. The Chronicle of Alberic de Trois-Fontaines records that "Hastingo" sold "civitate Carnoto" to "Turonensi comiti Theobaldo" in 904[28]. The accuracy of these two reports is uncertain as it is unclear whether Hasting ever was comte de Chartres.] Vicomte de Tours: "Domni Fulconis Andecavorum comitis, Tedbaldi Turonorum vicecomitis" subscribed the charter dated 30 Oct 909 under which the testamentary executors of "domni Gauzuini" donated property to Saint-Martin de Tours[29]. "…Tetbaldi vicecomitis…" subscribed the charter of "Hugo rector abbatiæ sancti Martini" relating to Tours Saint-Martin dated 931[30]. The identity of the husband of Richilde, and father of Thibaut [II] and Richard, is confirmed by the charter dated to [944] under which "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[31].

m firstly --- .  The primary source which confirms this first marriage has not yet been identified.  It is likely that the only indication is provided by the charter, dated to [980], under which “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)[32].  This charter confirms that Richildis was the mother of Richard and that Richard was the brother of Thibaut [II].  However, the absence of a phrase in the text such as “matris sui” linking “Richildis” to “Theobaldi comitis” suggests that she was not his mother and that therefore the brothers were born from different marriages of the same father

m secondly RICHILDIS, daughter of ---. Richildis is named as second wife of Thibaut in Europäische Stammtafeln[33] but the primary source on which this is based has not yet been identified. The charter, dated to [980], under which “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)[34] confirms that Richildis was the mother of Richard and that Richard was the brother of Thibaut. However, it provides no indication of the name of their father and therefore of Richildis’s husband.

Comte Thibaut & his [first] wife had one child:

a) THIBAUT [II] ([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]. He succeeded [his father] in [944] as THIBAUT I "le Tricheur" Comte de Blois, Vicomte de Tours.

Comte Thibaut & his second wife had two children:

b) RICHARD (-969). “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 not his mother and that therefore the brothers were born from different marriages of the same father. Archbishop of Bourges 956/57.

c) daughter . The Chronicle of Nantes records the marriage of "Alanus dux" and "Theobaldum comitem Blesensem…sorore sua"[37]. Given the date of her marriage, and assuming that the estimated birth date of her brother Thibaut [II] is correct as shown above, it is probable that this daughter was born from her father's supposed second marriage. The Chronicle of Nantes records the marriage of "Theobaldus comes Blesensis…sororem suam relictam Alani Barbætortæ ducis" and "Fulconi comiti Andegavensi"[38]. m firstly (before [949/51]%29 [as his second wife,] ALAIN II Duke of Brittany, son of MATHEDOI [Matuedo] Comte de Poher & his wife --- de Bretagne (in Brittany [before 919]-952). m secondly (after 952) as his second wife, FOULQUES II Comte d'Anjou, son of FOULQUES I "le Roux" Comte d'Anjou & his wife Roscille de "Loches" ([920]-11 Nov 958).

Roscille of Blois (b. 925 ), daughter of the Thibault the Elder, Count of Blois and Chartres and Richilda Gothia.

She had a brother Theobald I of Blois, called Theobald the Cheater.

In 948 she married Alain Barbetorte at Blois. They had one child: Drogo of Nantes , also known as Dreux (b. 950 , later Earl of Nantes, who died in 958).

Alain Barbetorte died in 952.

In 954, she married Fulk II of Anjou . Fulk II took control of the county of Nantes on behalf of Drogo, son of his new wife and Alain Barbetorte. Drogo died at Angers in 958 in ill-defined conditions (perhaps poisoned by Fulk II).

No one knosw the exact date of Roscille's death.
