The area occupied by present day Sandford lies mostly, but not entirely, in the 19th Century Civil Parish of Wareham St Martin. This parish consisted of three distinct areas linked only by roads. These were:
• The Northern Eastern part of Wareham including Northport.
• Carey, Trigon, Cold Harbour, and Bere Road.
• Sandford, Keysworth, West Holton, Holton and part of Organford.
The first area was the "in parish", and the last two areas were the Western and Eastern parts, respectively, of the "out parish", so Sandford lay in the Eastern part of the out parish.
