Henry, This may help a little! A popular rumor was that someone possessed a Daughter's of the American Revolution application listing Francis, Sr and Samuel as son's of Andrew. If this application ever existed it was never filed with the DAR. Hugh Floyd, son of Francis Sr filed an application with the DAR swearing that Francis was his Father and Samuel his Uncle. Although I'm sure that they are related, the DAR application does not mention Frederick or James. A friend researched this for me several months ago.
