Really not all that long ago....
My grandfather’s Dad fought in the Civil War for Indiana. I have no idea what unit he was in. After the war, he named one of his sons after Robert E Lee.
It’s interesting how some of us, if we’re old enough, still have memories of relatives who remembered someone who fought at Gettysburg. My Aunt told me stories about my gg grandfather who fought with the 18th Mississippi (Barksdale’s Brigade). Barksdale was killed there.
