Anyone know how well the Scots-Irish got along with the Poles, Italians, and Lithuanians who poured into Pittsburgh at the turn of the last century. I know that my ancestors caught more hell from the Irish Catholics than from the Anglos and Scots.
My Scotch-Irish ancestors in Pennsylvania intermarried with Irish Catholics. I've got a couple of Orange/Green intermarriages in my family tree. Complicating matters even more, my wife is Polish and Italian.
Random thought: Maybe my blatantly "Orange" (Scotticized Huguenot) surname was the real reason the Irish nuns at St. Mel School hated me so much. And I thought it was just sexism and anti-intellectualism...
