The highland tribes of Scotland are ethnically a mix of Irish & Scandanavian, their language, the tartans, the bagpipes came from Ireland. Scottish Gaelic is common to the Highlanders & Ireland (ref 'History of English' Faber & Faber Books - 'History of the English Speaking peoples', Winston Churchill))

The 'Lowlanders' between the English border & the highlands are & were the true 'Scottish' who spoke their own language different from the highland gaelic & English to the south. They were the first to adopt English in the 1700s when it begame fashionable to be able to speak "King's English". The highlanders retained gaelic & in remote places still speak it and can communicate with similar communities in remote parts of Ireland.

The Glasgow lowlanders are more of a polyglot mix because of Glasgows closeness to Belfast and that ferry's ran constantly between the two cities.

Geordies are unique & have a strong Norwegian influence, they differ markedly from the lowland Scots just a few miles away.
