FWIW I know of several people here in NE Mississippi that had Grandfathers that fought during the Civil War. Until two years ago, there were two men that were Real Sons of Confederate soldiers, meaning that their Fathers were Confederate soldiers. The last Confederate widow in Mississippi passed away in 1987.
Maybe they had grandfathers that fought in the Civil War. As men turn into old men those tails get bigger and bigger. My grandfather once caught a whale... Never trust a grandpa :) Miss him every day.
Was his name Mohammed?
