As a Southerner and of Scottish descent, I was told the stories by family. There is a book that has the supposition that war was inevitable, because of the difference between Anglo Saxons in the North and Celts in the South. I believe it was written by Randall Wallace of Braveheart fame.
Interesting.
First time I have heard about the Anglo vs. Celt theory.
Curiously, I had two great-great grandfathers who fought in the Civil War.
That generation of my family was 100% German, which I believe officially makes them Saxons. They were Lutheran ministers and farmers who settled in Peoria, Illinois, and fought for the North.
By my generation, one of my grandfathers married an English Quaker woman (my grandmother), so I guess I am definitely Anglo and Saxon!
Ironically, I spent a large part of my youth in the western Carolinas. My mother and I both had a genuine love for the people and the culture of the Old South.
I have not been in a southern state since the 1980s, so, I imagine my memories of the Old South are long gone.
