Maybe "my" Margie never married!
Did any of "your" Margie's siblings, assuming that their surname was Vance, have a child named James?
I have Watts on my mother's side. They were in NC prior to 1771. Before then they were in VA.
In 1869 my Jones' left NC and with them went some Watts. One couple went to MO and the rest went to KS. From there they spread out and with different surnames. I think a line went to Tyler, Texas. This TX connection information is not available to me right now.
