I have quite a bit of information and some speculation on Jefferson and his family. I collected much of it to separate him and Jefferson D. Alexander, also of Henry County, TN, of about the same age. Both families apparently came west from the borderland of SC and NC.
E-mail me if you would like to exchange data. I would prefer not to post because my Jefferson file may contain some errors; yet some people take posted information and run with it as fact.
