Beeston is a village in the county of Norfolk, in the civil parish of Beeston with Bittering, west of East Dereham and south of Fakenham. It may also be known as Beeston All Saints or Beeston-next-Mileham to distinguish it from the three other villages in Norfolk named Beeston. Sir William Calthorpe made presentations to the rectory of Beeston in 1460, 1481, and 1492.
