Thanks again! On all the census for William Austin Powell aka M.A. Powell, he lists his birth state as TN. That's why I keep thinking maybe there is a closer connection to this Powell/Byram then we know about. The census on one for him does show his Mother's birth place as SC...and his father also TN.
I seem to have run out of theories. Maybe a neighbor or something of Levi Byram? Powell was born in 1843. I wonder if this James Powell's family ever lived in TN?
I'm about ready to just put him up for adoption to any family who needs a missing someone.
