Ancestry has a Parish Map of Dorset, which helps understand the interplay between locations. Beaminster Registration District includes the town and parish of Broadwinsor (Broadwindsor) together with the adjacent parishes of Stoke Abbott, Burstock, Pilsdon, Bettiscombe, Mosterton, South Perrott, Cheddington, Marshwood, Thorncombe, Netherbury, and of course, Beaminster. Some records about people in these areas refer to the registration district of Beamister and others to the Parish, and sometimes the town or hamlet. This is just a complication of locations and interpretations of records.
