Thank you for checking! It will just be a puzzle : ) I'm finishing up a genealogy project and there is one more McCarthy from Richmond that I haven't mentioned, Edward McCarthy (1827–1880, Richmond). I have never found any Civil War mention of him like I did with the others. But it seems odd for a military aged man, in the heart of Richmond, to not have fought, especially when his all of his brothers and cousins were enlisted. As a last resort, could you see if you find anything on him? If not, maybe he had a medical condition or was assisting the war effort in some other way. After the war he ran a wholesale grocer and liquor store, so perhaps he was involved in supplies as opposed to the fighting.
