John (Jehu) Evans Watts (b. 1795 in GA) had three sons, Josiah (b. December 09, 1818), George (b. 1822) and John (b. November 17, 1823).George and John lived and died in Copiah County.
Josiah married three times and moved to Bienville Parish, LA. Cynthia Putnam isn't one of those wives.
There is a small possibility that there may be an unknown child of John Evans Watts.The spread of births leaves some possible years.However, nothing other than your Watts living in Copiah County indicate a relationship.
Note that John, Josiah and George are EXTREMELY common among SC and MS Evans lines.John is used interchangably with Jehu.Thus John Evans Watts is most likely from this stock on his mother's side.
E.g., Three Evans brothers, John "Capt. Jack", George and Josiah moved to Wayne County, MS Territory in 1809.We have genealogy on John and Josiah, but George disappears after 1830.Have you run across a George Evans in Livingston Parrish?Related families often travel together.
John Evans Watts is a half brother to Josiah Watts of Wayne County, MS.We haven't proven all of Josiah's children, so there is a possibility your Watts could be from that line.
