Don't know if this could be your soldier or not. There was "Charles Junghaus" with the 3rd MO Inf who died 5/17/64 at Resaca GA. Interestingly, there was a Herman Junghaus with the same regiment and company. Could this have been a husband-wife or boyfriend-girlfriend situation? I did a quick look at the 1860 census but couldn't find Herman Junghaus with that spelling. Will try to do a little bit more looking! Fascinating! Good luck! Kerry
