I am looking for the parents of William Vance who died 1803 Allegheny Co., Pa. His will states that his wife was Mary and his children were Andrew, William, John, Mary, Ann Thompson, Agness Camble and Jane Boyd. I am also looking for the children of Andrew, William and John in order to try to find the parents of my gg-grandmother Mary Vance who married a Mr. Neal ca 1839. I would appreciate any suggestions that you might tell me. Thank You, Clare Pebworth
