Prior to the 1820 census, Maine’s census records were taken as part of each Massachusetts census. The Kennebec and Hancock records in the 1800 census list where each person lived before coming to Maine, but only the Kennebec records consistently list dates of emigration. The Houlton Plantation census records for Washington County in 1820 are missing, as are half of the 1810 records for Oxford County, and part of the 1800 records for York County.
A state census was taken in 1837. However, only some of the records for Portland, Bangor and unincorporated towns have survived and been put on microfilm. The Maine State Archives has them on file. Enumerations for Elliot can be found in a volume at the Maine Historical Society.
