OMG, how did you find that out? Family stories I'd say. I have atleast 6 gg grandfathers who fought with the CSA, and a husband from Florida with one CSA and one Federal gg grandpa, with another relative (his-a Yankee) who died at Nashville. I am with you even though I have Yankee family on his side to contend with. It is hard to control your emotions when you know all of this stuff!
My husband had a great uncle in a Nazi hospital, a radio operator shot down, who had a Nazi doctor rebreak his leg just for kicks! Atleast they let him live. OMG!
