Larry,
We may have him?
I found this at http://9thtexas.tripod.com/historicroster.htm .
Barnes, Gideon R., age 29, born about 1832, 2nd Cpl., Co. C, enlisted 4 Oct 1861 at Sherman, Grayson Co., TX
Well, no longer "G.R. Barnes", apparently these guys have transcribed the Compiled Service Records and discovered his full name was "Gideon R. Barnes".
What do you think?
