Theobald VI, Count of Blois

He was son of Louis I of Blois and Catherine of Clermont.

[1] Theobald married twice: with Maud of Alençon[1] and with Clemence of Roches, but remained childless.

Clemence married Geoffrey VI, Viscount of Châteaudun, as her second husband.

[2] After living withdrawn in his castle in La Ferté-Villeneuil for a few years, Theobald died in 1218, leaving his possessions to his aunts Margaret and Isabelle.

The northern part of Blois was erected into the County of Chartres for Isabelle; Margaret received the remainder of the County of Blois, and his heirs sold Clermont to Philip II of France.
