The House of Mayenne is a family of western French nobility that existed from the 11th to the 13th century. It was written by Count Fulko III. from Anjou, i.e. before 1040, the castle Mayenne on the road from Le Mans to Fougères and thus performed border tasks opposite Brittany. After her extinction in the male tribe, Mayenne fell to Alain II. d’Avaugour from the First House of Avaugour, the son of probably the last family members.
