I have checked the 6th/9th & there are a few M. Young's. I have the records of a M.W.J. Young of the 6th & a M.F. Young of the 9th. These records are quite small also & it's impossible to tell if these men are Moody. I ordered them just to check for that possibility.
I have to believe that company I was one of the companies whos records were lost at Shiloh.
The best link i've found on the 6th TN Infantry:
