Sorry it's taken me so long to look at the message board. I don't think the Andrew Caldwell you're looking for can be the same one as the brother of our George. They were much earlier than you mentioned. I don't know much about the brothers, except they are the little known sons of Joseph Caldwell and Jane McGhie from Ireland. Everyone knows a lot about the other brother, John, but not much about George or Andrew. I am trying to find out more about them in the event that either one of them is the father of our George Caldwell(the younger) who is the father of our Garland Caldwell. It is a line that hasn't been researched much.
