Hi! I am a 6th generation descendent of Philip Younce and Margaret Burkett through their son Abraham. My findings do list Philip's second son as Joseph, born in Ashe Co., 1810 or 11. But his spouses don't match your Joseph's. His first wife was Amy Knife (married 9/2/1828) and the second was Lucinda Michael(married in 1853). Philip's Joseph died 11/7/1872.
