Thank you very much for the info and the link. I cans see several other families have made the connection between ML Nance and James Harvey Nance but I really want to be sure. If this is indeed the case, most of the work has been done and we go back farther than I ever imagined possible.
I've nailed down siblings of ML and have been trying that route. Reading that Ruff was the last surviving member is helpful and will try to get confirmation through him.
I'm also solid on ML of Tampa as my family members can confirm that. My cousin in ML the 5th!
Thanks so much for your help with my new addiction.
