What Is The Deal With The "Scots-Irish"?

Borne out by this predominant ancestry map from the 2000 census. Along the Southern Appalachians, where you’d expect to find Scots-Irish, the census-takers received the answer “American.”

(But why not Swiss? I seem recall somewhere hearing “Hell I’m a Baptist - I don’t wanna guard no pope!”)

Beginning in Colonial times, many Irish immigrants did come from Ulster. Per R F Foster’s Modern Ireland 1600-1972:

But it is true that “Scotch-Irish” (later “Scots-Irish”) was invented to distinguish the more established Protestant Irish Americans from the wretched refuse. Even if the more established folks’ immigrant forebears hadn’t Worn the Orange. Many of their descendants simply forgot their roots.

The grandmother who helped me was born in Indiana, raised Presbyterian & abjured strong drink because she’d had to drop out of school after her father broke his leg while drunk & had to stop carrying a hod for a while. But she was proudly “Scotch”-Irish. She married an Irish-American whose people came over during the Great Famine, I think. (But I’m not sure–he died just after I was born.)

My father’s parents came from East Galway. I’m told he was beat up as a boy for not being American enough. He died in military service when I was 4 years old. I’ve got the flag that was on his coffin for the wake–Red, White & Blue.

That’s actually one of the defining characteristics of this group. They very quickly forgot/abandoned any connection to the British Isles and identified themselves as American. (No hyphen, thank you.)
