Unfortunately, I don't know the hospital where he died. We didn't even know he died in Richmond. I was surprised to find he died in Richmond after being wounded at Gettysburg. The other record we have found that shows he died at Richmond is the IGI file. A historian from Richmond found a W. H. Herman buried there. This could be him, because that is the German spelling of the name. Will try to find out what hospital he was at. Thank you for writing!
