If you get a reply to either of your questions, be good enough to share the information (if the source appears credible from the referenced documentation).
At present you may know that we have been told by early in-family sources that John Fly, b. 1772 married "Sarah Jane Trader, a beautiful English lady. - The Traders were from Scotland."That's it.To the best of my knowledge we have NOTHING more bearing on the matter.
We have nothing at all on Mary Belle Hester's origins. NADA. Caleb and wife were the last of the Fly brothers, sons of "Rev." John, to move to Yalobusha Co., MS.Rev. Joshua and Rev. David went there first together; then Col. William joined them; and finally Caleb.Col. William moved on in a few years to Sharon, Madison Co., MS. where he remained until he decided to move to Texas. He died there in 1855, the same year that "Rev." John died.
Are you in the branch of the family under Caleb?I have considerable information on the descendants of Caleb and Mary Belle, if you are interested.
