My Scottish great grendfather was born in British Ireland, which is now Northern Ireland, I think. But my father always said he was Scotch-Irish. I found out something interesting though recently. My father and mother are both descended from Wm, Bradford, the governor of the Mayflower Colony through two of his grand children.
While searching my ancesters, I went back more than a thousand years and found that my English ancestors came from Austria and my Irish ancestors came from Turkey and my Scottish ancestors came from Sweden ! So what does that make us?
