 Corfham was already by 1066 (when it was held by King Edward) the "caput" (the centre of administration) for both Culvestan and Patton.It is believed that by the 12th century the "caput" for both hundreds was moved to Aston, northwest from Corfham Castle on the other side of the River Corve.Aston was near the tumulus known as Munslow and the place later became known as Aston Munslow.
