Drogo of Mantes
Drogo of Mantes (996–1035) was the count of Valois and the Vexin in the early eleventh century from 1027 to his death. 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 Waller (Gautier) III, Count of the Vexin, and Ralph the Timid, earl of Hereford.
