apphia Williamson married Thomas Steward Mar 14 1810 Maine

For 30 years I have searched Maine records for Apphia Williamson who is recorded in Canaan Maine marriage record with Thomas Steward.Thomas in the son of Phineas Steward.They relocated to Solon and then Moscow.She is buried there and gravestone notes birth in 1792.She can be followed on the censu and in 1880 whe is with daughter Harriet Steward Baker.I have read McKinnon and believe she may be daughter of Jonathon but lack proof.
