Dan,
We couldn't possibly have any fun if we didn't have both blue and gray.
In answer to your question, I have not documented fully on my husband's side yet, but have found four Confederates there.
On my side so far: on my mother's side, I have seven. On my father's side, I've found eight.
However I have not looked thoroughly at my Northern relatives so I feel sure there are some Yankees in my brood too. And on my husband's side, since he's a direct descendent of John Quincy Adams, I've no doubt there will be some Union soldiers there too.
Also, in answer to your question about the SCV, my husband is a member.
