I liked the fact that they touched on the civil war being a lot less north vs south than we believe today. As Asa McCoy told Jim Vance, There are as many folks around here fighting for the union as for the confederacy.
Some recent family history has emerged that shows how common the mixed loyalties were. Turns out that my great grandmother’s grandfather and his brother signed up to fight for the union on the same day but the brother never returned north. Her grandfather simply said he’s still living. It appears that he went south with the union and switched sides or remained after the war.
Same thing happened in my family. My GGG Grandfather was in the US Army prior to the Civil War, but when hostilities broke out, he sided with the Confederacy, while his brother signed up to fight for the Union.
They both survived the war, but I don't believe they ever spoke again.
Southern Appalachia was very much more divided than most people learn about. I did a study of it during the Civil War in place of a thesis. It was quite enlightening- a lot of people who put up Rebel flags nowadays would be quite shocked to learn that great-great grandpa was probably dodging the Confederate draft, or even joining the Union army.
