The only reference I have is the 'Tennesseans in The Civil War' They don't mention where the soldier was from. There is (1) J.J. and (7) John McKinney and (10) William McKinney. I am sending the one J.J. McKinney. If you could give me a little more information on the unit your John and William served in it might help pinpoint the right man for me and someone else on the list with better references than I have. Here is the one J.J. McKINNEY, J. J. K Co. 19/20 Cav. There are so many John and William under all surnames. I am also having problems with those giving names in one of my lines. Hope I can help.
