Parts of the family stayed in GA, parts went west and north, to Alabama and to Virginia. All the living men in my family except for my great great grandfather (who was a child) died in the civil war.
They fought on both sides. Literal brothers against brothers.
One of them kept a diary, I've never read it, but I know my dad has a xeroxed copy.
We have good records of who they were and where they fought. We helped identify the remains of one of them in the 90s, when I was too small to realize what was going on.
