Scots-Irish

[Blackrose87]

Thanks for all the replies! It's very interesting history that I knew next to nothing about.

It seems that the Ulster-Scots flourished on immigrating to America. I don't have an accurate number for the population of Ireland describing themselves as Ulster-Scots, but at a guess it would be no more than 750,000 to 1m.
(given that the population of n Ireland is ~1.5m, with around 55% Protestant. Then the other 3 counties of Ulster have a small population of Ulster-Scots added to this.)

With so many having Ulster-Scots heritage, are there many speakers of the Ulstér-Scotch language?
From what I'm aware, it's a dying language here maybe it could have more speakers in America than in Ireland?
