Bob: The Adams Book says that John Adams m Elizabeth and had 3 daughters--Elizabeth Ann, Mary Ann & Sally (according to Conewago Baptismal Records). They have him listed in 1810 census in PA--Straban Twp. They have a John & Elizabeth buying and selling land in Cambria Co. Allegheny Twp. between 1810 & 1820. (This is the area where the Adams settled so we think it's probably them but have not researched them in particular.) Doris Snyder
