FNG checking in. Retired USMC. Doing genealogy work on Ancestry. Most of my Civil War ancestors served in the Confederate Army. Interestingly, my great grandfather was a 2nd Lt in the 1st Mississippi Mounted Rifles (Union). So did three of his brothers. I’m trying to get some insight into their motivation. After the War, they all moved to Arkansas. Probably persona non grata. Anyway, looking forward to learning from all of the collective knowledge on the site. Thanks.
