Do not have a clue if this is the same Jacob you are looking for or not.
My Jacob, born about 1768 in Pennsylvania, married Catherine ?? in 1809. Have no idea what happened to her. He also married Agnes McElroy in 1848.
HOWEVER, that said, I have 3 children I now doubt were Catherine's, unless the marriage date is wrong, because they were born between 1789 and 1807. There are two more born between 1810 and 1812 and then no others.I am now beginning to believe that,just perhaps,there may have been 4 wives, not 2.One he might have married about 1788 and another between 1812 and 1848.............or who knows, maybe a couple more here!
He died after 1850 in Caldwell County, Kentucky.
What other informtion do you have on 'your' Jacob?We may have the same one.
