Guy - I don't know if we can exchange useful info or not. I do know that a Zimmerman signed a land transaction record as a witness for John McCullough, in KY. McCullough was my 3G GF and the signature of Zimmerman was quite distinct. It was extremely legible - unlike so many of the other signatures of those who could write in those days. I think Zimmerman and McCullough may have been neighbors. Alan McCullough
