William d'Ecouis
William d'Ecouis was an early Anglo-Norman baron, who is mentioned in the Domesday Book of 1086 as a substantial holder of land and manors.
William d'Ecouis founded Middleton castle, a motte-and-bailey fortress thought to be constructed from timber, the remains of which is a scheduled monument listed as Middleton Mound. The motte, surrounded by a ditch, is at the west side of Station Road in Middleton, Norfolk, a village south-east from King's Lynn, on the A47 road.
