If this is too personal/ none of my business, just say so. I won't take offense and certainly do not intend to give any.
You offer your grandfather as a Confederate veteran. Right? I'm not doubting you, it's just that, my grandfather was born in 1876, my father in 1904, and I in 1948. That's a pretty good stretch in generations, is it not? Your grandfather must have been a very young soldier, and people can have children late in life through generations. Of course, you could be old as dirt too! :wink:
