JEAN de Vendôme, son of GEOFFROY "Grisegonelle" Comte de Vendôme & his wife Mathilde de Châteaudun (-La Charité-sur-Loire [1185]). A charter dated 19 Jul 1126 records the restitution by "Joannes filius Goffridi Vindocinensis comitis" of property to La Trinité de Vendôme[1031]. "Goffridus comes Vindocinensis dictus Grisagonella" confirmed the possessions of La Trinité de Vendôme, for the soul of "uxoris mee Mahildis" and with the consent of "duo filii mei Johannis et Goffredus", by charter dated to [1102/29][1032]. A fragmentary chronicle of the dukes of Aquitaine names "Johanni Comiti primogenito Galfridi Grisagonellæ Comitis Vindonicensis atque Mahaudæ Castridunensis" when recording his first marriage[1033]. "Goffridus Grisagonella comes Vindocini et Johannes filius eius" donated part of the forest of Gâtineau to the abbey of La Trinité de Vendôme by charter dated 1139, which states that Geoffroy had recently returned from Jerusalem, later consented to by "Lancelinus filius Johannis comitis Vindocini, Mathildis filia eiusdem Johannis, item alia filia Mathildis" and witnessed by "domnus Lancelinus de Baugenciaco…Goffridus de Chaorciis…"[1034]. Comte de Vendôme. "Joannes Vindocinensis comes" part of the forest of Gâtines to the abbey of La Trinité de Vendôme, with the consent of "duo filii mei Burchardus primogenitus et Lancelinus…Agatha uxor Burchardi filii mei", by charter dated 1147[1035]. The Chronicon Vindocinense records that "Joannis comitis" was excommunicated in 1177[1036]. "Burchardus comes Vindocinensis" approved the donation of "bonæ memoriæ Johannes pater meus comes Vindocinensis" to the abbey of la Charité-sur-Loire by charter dated to [1185], witnessed by "Gaufridus frater noster, Johannes de Laval consanguineus noster, Matheus de Bellomonte"[1037].
m firstly [BERTHE du Puy-du-Fou, daughter of GEOFFROY du Puy-du-Fou & his wife ---. A fragmentary chronicle of the dukes of Aquitaine records the marriage of "Johanni Comiti primogenitor Galfridi Grisagonellæ Comitis Vindonicensis atque Mahaudæ Castridunensis" and "Bertham", daughter of "Gaufridus de Podio-Fagi, filius Hugonis, ex eiusdem Ducis [=Willelmi Pictaviæ Ducis Aquitaniæ] progenie"[1038]. The difficulty with this suggested marriage is the dubious status of the source, discussed fully in the document AQUITAINE DUKES. Nevertheless, it is likely that Comte Jean did marry twice, and that his first wife was the mother of his son Bouchard [VII], given that Bouchard´s wife and his father´s [supposed second] wife were probably sisters.]
m secondly ([1147]) RICHILDE de Lavardin, daughter of [AYMERIC "Gaimard" Seigneur de Lavardin & his third wife] Marie --- (-24 Sep ----). "Richilda comitissa Vindocinensis" donated property "de Villeriis" to the abbey of La Trinité de Vendôme, with the consent of "Goffridi filii mei", by charter dated to [1147][1039]. Her family origin is indicated by the charter dated to before 1185, under which "Wlgrinus miles monacus noster" [son of Ingelbald Brito] donated the mill of "Beto" to La Trinité de Vendôme for the soul of "Petro filio suo quem monacum fecimus", confirmed by "Maria uxor eius et quinque filii eius Goffridus, Herveus, Ingelbaldus, Petrus, Mauricius, et Agnes et Domitilla filie ipsius" and in the presence of "Johannes comes Vindocinensis et Richildis uxor eius, neptis Wlgrini…"[1040]. This family origin is confirmed by the charter under which [her son] Barthélemy Archbishop of Tours confirmed donations made to the abbey of Saint-Pierre de Preuilly by "bonæ memoriæ Engelbaudo avunculo et predecessore nostro"[1041], the latter being identified as the maternal uncle of Richilde de Lavardin. Although the sources quoted in this paragraph indicate that Richilde was the sister of Jean de Lavardin (son of Marie by her second husband Geoffroy de Lavardin), and that Richilde was the daughter of Marie, no primary source has been found which confirms that Richilde and Jean shared the same father. It appears more likely that Richilde was the full sister of Agatha de Lavardin (and therefore probably the daughter of Aymeric "Gaimard" Seigneur de Lavardin) and that their two marriages, respectively with the father and son Jean Comte de Vendôme and Bouchard [VII] Comte de Vendôme, were arranged because they were full sisters and each enjoyed rights to Lavardin. Clearly the Vendôme family was anxious to secure the Lavardin inheritance by marriage with the heiress. It seems more probable that Agatha´s marriage with the Vendôme heir was arranged first, and that Richilde´s marriage provided "back-up" for Jean Comte de Vendôme in case the Bouchard/Agatha marriage proved childless (and his other children died without heirs) to increase the chances that Lavardin would still remain within his family (or more importantly that it would not be lost to another family). "Johannes de Lavarzino…et Richeldis comitissa soror eius" donated property to La Trinité de Vendôme by charter dated to before 1188[1042]. The necrology of Vendôme La Trinité records the death "VIII Kal Oct" of "Richilda comitissa fundatrix infirmarii"
