Information was found relating to Belchamp Walter Water mill and various other areas of Belchamp Walter's history.
The Brasses of Belchamp Walter
The Belchamps
The EASH have a good synopsis of how the Belchamps came into being and why they are named. Belchamp St. Paul's was so called as it was the "possession" of the Canons of St. Paul's in the city of London. Belchamp Walter and other locations around the area were "possessions" of the Abbey and Abbot of Edmundsbury (Bury St. Edmund's). Although not well documented there appears to be a rivalry between the two ecclesiastical entities.
