Yeah that’s who my mom is descended from and I’m from Alabama. What happened is There was a migration of scots Presbyterians to Northern Ireland, and then from Northern Ireland to Appalachia. In the south they call that ethnicity scots-Irish but over there I think they call it Ulster Irish. For a while there were a series of books about the scots Irish (eg “born fighting” by senator jim Webb and the chapter in outliers by Malcolm gladwell about why scots Irish are so violent—-for some reason all the books were about violence...I suppose because the people who buy the books want to thing if themselves as brave and dangerous).
