And despite the popular mythology, promoted about a century ago by Romantic researchers claiming Ulster ancestors, the white settlers of the Appalachians were not solely, or even chiefly, Ulster Scots (or "Scotch-Irish" as they're usually called).

Ulster Scots were the largest minority among the settlers. English immigrants were a close second, with immigrants from Scotland, southern Ireland, France, and Germany following in order of numbers.

A good rough estimate is that about 40% of the Appalachian settlers were from Ulster, 35% from England, and the remainder from elsewhere.

The Georgia mountains weren't settled until the early 19th century.
