Theobald I
Theobald I was the son of Theobald le Vieux of Blois, who from 908 on was viscomte of Tours. Theobald le Vieux's wife, the mother of Theobald I, was Richende De Bourges, a great-granddaughter of Rorgon I, Count of Maine. Theobald I was initially a vassal of Hugh the Great, Duke of France. Around 945, Louis IV was captured by Northmen and given over to Hugh the Great, who placed the king in Theobald's custody. After about a year in his vassal's custody king Louis negotiated his freedom by offering Hugh the city of Laon which Hugh then gave to Theobald. Theobald was the count of Tours from 942, was also count of Blois and in 960 count of Châteaudun and Chartres.
