I am descended from a MARTHA (Williamson) THOMPSON (1791-1866) who married Archibald Thompson (1785-1852) and resided in what was Mercer County, PA. Husband and wife were residents of Mercer County when married 25 AUG 1806 by Hon. Arthur Harry (Justice of the Peace) in Lackawannock Township, Mercer County. I am guessing MARTHA was daughter of a JAMES WILLIAMSON (1754-1818). MARTHA's oldest boy was named Robert (1808-1852), likely after her father-in-law Robert Thompson (1761-1834). Her second son was named James (1812-1891), again, likely after her father, James Williamson. Please advise if you have anything on my Williamson lineage. My e-mail is email@example.com
THANKS in adavance. Best wishes.
