My own LAY line can only be traced back to the 31 Jan 1791 second marriage of my 4GGF John LAY, son of John LEE, to Hannah HENRY, dau of Nicholas HENRY of Frederick Tp, Montgomery Co PA (Faulkner Swamp Ref Ch records, Montgomery Co PA) and the 1800 Census of Mifflin Tp, Cumberland Co PA).
My 4GGF John LAY was born before 1755 in PA, first married Eva Margaret HENRY (my 4GGM), had 5 sons and 3 daughters in 1800 (at least 2 more sons and 1 daughter were born after 1800), and died c1820 in Toboyne Tp, Perry Co PA. His second wife, Hannah HENRY, was born 24 Sep 1771 Franconia Tp, Montgomery Co PA (now Philadelphia Co) (were his two HENRY wives sisters?). His oldest child, a male, was born between 1774 and 1784. A daughter, Catharine LAY, 1792-1876, and her husband, Christian HENRY (1790-1871) were both born in Bucks Co PA. Another son, my 3GGF, John LAY, b bet 1790-1794, had a Sheriff's Deed issued on his Mifflin Tp, Cumberland Co, land in 1825.
