Hello Iris. Nice to hear from you. I won't be abe to help you at all with that process. I'm a Professional Genealogist working for an Author in Missouri who is searching several Southern Gentry families as they relate to the political world; Signers of the Declaration of Independence, etc. etc.
We are trying to prove parents of John Madison 111 who married Agatha Strother.
The Madison Genealogies that I've searched thus far do not identify him, but it is a new assignment and the Madison Family Forum is a good place to leave a query.
