I have J. R. Cowan whose residence is not listed. Enlisted as a private (date unknown) He also had service in "F" Company, Alabama 4th Calvary. As you are probably aware the State of Alabama adjoins Floyd County, Georgia and this individual could well have enlisted into a Alabama unit.

If you would indicate the names and units of the two brothers who served in Tenn. I would attempt to find more detailed information than that shown in your post.

I would suggest that you obtain the Combined Service Records of these men from the Archives. The information contained in these archive records sometimes indicate quite a bit of detailed information. In some instances there is practically no data. There are also some commerical locations that can supply copies of information contained in the CSR. The fees are practically equal but the service and the copies are much better when obtained from a commerical source.

Hope this is of assistance...Sorry I don't have more data.
