The manor of Moreton was held in 1066 by Saxi and in 1086 by William d’Ecouis in demesne. It was assessed at 1 hide and 20 acres of ploughland, with woodland for 400 pigs and 20 acres of meadow. Another 43½ acres held by a free man were annexed by William, and were held from him by Ralph in 1086. By 1182 the manor was in the hands of William d’Avranches, and it was still in that family when the male line failed in 1235.
There was apparently a church in the 11thc, which was given to the abbey of Saint-Etienne de Caen by William d’Ecouis – the gift recorded in a charter of William d’Avranches dateable between 1174 and 1182. The church was seized by Edward III during the war with France, and it remained a royal possession until the late 15thc.
