Viscounts of Thouars

The first viscounts of Thouars appeared at the end of the 9th century, somewhat earlier than those of Châtellerault, Lusignan, etc. They represented the count of Poitou (also the duke of Aquitaine) in the territory he had enfeoffed to them. The family of the viscounts of Thouars doubtless originated in the surroundings of Poitiers where they held lands in the 10th century. At this era, they were patrons of the abbeys at Saint-Cyprien de Poitiers, Saint-Jouin de Marnes (15 km to the south of Thouars), Saint-Florent de Saumur and Saint-Martin de Tours. In the 11th century, following Geoffrey II of Thouars's marriage with Agnes of Blois they added to this list the abbeys of Bourgueil and Marmoutier.

Before 876-903: Geoffroy I. His successors Savary and Aimery are likely his sons or his nephews.

903-929: Savary I. A follower of the Count of Poitou Ebles Manzer. He participated in meetings held by the Count of Poitiers. In 903 Ebles rewarded him by giving him the authority of the Abbey of Saint Maixent.

929-936: Aimery I. Brother of Savary I, he owned property near Poitiers and was admitted to the Abbey of Saint Maixent (which was very rich). He married Aremburge, and they had two sons, Savary II and Aimery II.

936-943: Savary II. Son of Aimery I; he had no sons.

943-960: Aimery II. Son of Aimery I. He was a faithful ally of his suzerain Geoffroy Grisegonnelle, Count of Anjou, who awarded him the goods Chavagne near the monastery of Saint Maixent to Faye near the Abbess and Bressuire Miss south of Thouars. In 955 he donated land, the Abbess Faye always to the benefit of the Abbey Saint Bonneval lès Thouars. Aimery II married Eleanor by 935, with whom he had a son, Herbert I..

Abt 960-987: Herbert I. Son of Aimery II. Geoffroy Grisegonnelle, Count of Anjou, appears as suzerain and protector of Viscount Herbert (it will be the same, however, vis-à-vis his son Aimery III). About 973, Geoffroy was in possession of the strengths of Loudun and Mirebeau and then encircled the area of the Vicomte de Thouars. Herbert married in 956 Aldéarde (or Hildegarde), daughter Cadelon I, Viscount of Aunay (Aulnay, Charente-Maritime) and Sénégonde.
