Drogo of Mantes

Drogo of Mantes (996–1035) (In French: Dreux de Vexin) was the count of Valois and the Vexin in the early eleventh century from 1027 to his death. He was the oldest son of Walter II, count of Valois, Vexin and Amiens, and his wife Adela. His father died between 1017 and 1024, leaving Vexin and Amiens to him and Valois to his younger brother Ralph. His capital was Mantes, thus his byname. He married Goda, daughter of King Ethelred the Unready of England and Queen Emma of Normandy and the sister of King Edward the Confessor. Their sons were Walter (Gautier) III, Count of the Vexin, and Ralph the Timid, earl of Hereford.
