Geoffrey I, Count of Perche

Geoffrey II, Viscount of Châteaudun and Count of Perche, son of Fulcois, Count of Mortagne, and Melisende, Viscountess of Châteaudun. Some sources say that he became Viscount of Châteaudun following his uncle Hugues II’ appointment as Archbishop of Tours. At that point, he was probably under the regency of his mother.
