Sanfordsville is found on a map from The American Atlas (London, J. Arrowsmith, 1839). It appears to be in southeast Cass (now Bartow) County, however the map is not specific enough to denote an exact location. Post office listings for Cass (now Bartow) County show a Sandfordville post office operating between 1831 and 1838. The spelling of Sanfordsville (map) vs Sandfordville (post office) is close but could be two entirely different locations. Please contact the Etowah Valley Historical Society with any additional information about Sanfordsville.
