I have his birthdate & Place as 31 Jul 1831 @ -----,Lancashire,PA. I also have 4 children but only have 3 names. Emma Laura, Abraham Lincoln and Elmer. Do you have the other child's name? What family line do you come down from? I come down the Abraham Lincoln line.
On the question of John's parents, it looks like I have Barbara Newcomer.....but I have heard of Maria Landis. I know that a Landis appears as the mother of Abraham's Mom...Barbara Landis. Maybe the records are slightly off? What do you think?
