Mary Gleason was my 3rd g-g-mother.Marriage date & place to John Beckley jr. correct as stated above.Not to muddy the waters, but family folklore has her parents as Amacy Gleason (have also seen "Amasa") born abt. 1756/1765 in Clyde, Wayne Co., NY.Married to Matilda Packard, born abt. 1774 also in Clyde.Looking thru the census etc. records shows Gleason's & Packard's there, but I can't confirm names dates etc., except I have seen others w/the same info looking too.Hope this helps!Please let me know if you find anything! - Patty Z.
