I have just started researching Bryan Fannin and his daughter Mary.
Some Burchett family trees state that Mary Fannin born 1746, married Burwell Burchett in 1771.
I have found a Land Patent for Bryan Fanning 1748 in Amelia County VA and I was hoping to find some marriage records. Sorry I can’t help you with your Fannin’s.
Thank you for the look-up.
