My ancestors served in the Civil War in Kentucky's Volunteer Cavalry (fortunately the Union Army). But had they been Confederate, I would have posted their service just the same.
3/4 of my family however is German, but again fortunate for me they all left in the 1760's, or the mid/late 1800's.
But realize it is not something that any of us control in any way at this point. My grandfather flew as a World War II fighter pilot on D-Day escorting our bombers across the English Channel, but I have also created profiles for German flying aces from World War I.
