Are Scottish people descendents of the Irish?

Question

I mean, did their ancestors come from Ireland. I haven't gotten a good answer yet.

Answer 1

Igstrike is basically right, but that's not the whole story. When the Romans came to Scotland, they found two distinct populations, the Britons, speaking some dialect related to early Welsh, and the Picts in the far North, speaking a language unknown to us, which may or may not have been Indo-European - perhaps develpoed from the language of the pre-Celtic inhabitants.

After the Romans left, thse two peoples were joined by Anglo-Saxons in the South, and Scots in the West, a tribe who crossed from Ireland, bringing with them the Gaelic language.

So the "Scots" were from Ireland; but today's Scottish people are descended from a mixture of all four peoples (plus newcomers).

Worth noting that Gaelic, still spoken in the Western Isles, has never been spoken in more thatn half the country; Scots English is at least as authentically Scottish. The Picts and the Welsh were absorbed by the others.

Answer 2

The Scots were originally from the Irish tribe the Dál Rioda , a kingship in the most northern tip of Ireland. "Scotus" was the Latin word for Irishman. The Irish were the Scoti who settled in Scotland as early as the fourth century, and eventually gave Scotland its name. The originator of the political territory of the Dál Riada in Scotland was Fergus Mór mac Eirc who arrived in Kintyre c. 500

Answer 3

There was a group of tribes called Kelts, who have been referred to as Gauls, Gallicians, Celtics, Welsh, Britons. They invaded Europe about 2,000 BC, conquering and interbreeding with the aborigines, and became so spread out that there is a Gallicia in Turkey, Poland, and Spain. When they reached Brittany on the western coast of France, they developed shipbuilding and crossed over to what is now England, Wales, and Scotland. Possibly the original Celtic Welsh went over to Ireland, but the Kelt nation reached Scotland first.
