Fulcuich (Fulcois) Count of Mortagne, son of Rotrou, Seigneur de Nogent. It has been conjectured that Fulcuich's ancestor was Hervé I, Lord of Mortagne-au-Perche, through his supposed mother, Hildegarde de Mortagne et Perche, wife of Rotrou, who is a known daughter of Hervé. Fulcuich married Melisende, Viscountess of Châteaudun, daughter of Hugues, Viscount of Châteaudun, and Hildegarde of Perche. Fulcuich and Melisende had two children: Geoffrey II Viscount of Châteaudun, I Count of Perche. Hugues du Perche Fulcuich was presumably succeeded as count by his son Geoffrey.
