He was son of Theobald II of Champagne and Matilda of Carinthia. Although he was the second son, Theobald inherited Blois (including Chartres), while his elder brother, Henry got the more important county of Champagne. He first married Sybil of Chateaurenault, which made him lord of Chateaurenault. Next he married Alix of France, daughter of Louis VII of France and his first wife Eleanor of Aquitaine. They had seven children: Theobald, d. young Philip, d. young Henry, d. young Louis I of Blois (d. 1205) Alix, Abbess of Fontevrault Margaret, married Walter of Avesnes, later Countess of Blois Isabelle (or Elizabeth) (d. 1248), to whom her nephew Theobald VI of Blois left the County of Chartres (alienated from Blois) and the lordship of Chateaurenault |
