I have information from a death certificate that states that my great great grandfather "William Calvin Johnson" was from Carroll county in Tenn. William was the husband of Ardelia D Moore from Franklin and the Wheelock area of Robertson county. William is buried near Franklin but Ardelia is burried near Corsicana in Navarro county. William was born in 1850 and died in 1893. I have not checked the court house in Franklin for any old records. Could this be the same person as the William T Johnson that you have researched.
