I have family pretty much all over the eastern seaboard, and elsewhere in smaller numbers.

Most the these are accurate overall.

However! There is another term for folks from the Carolinas, Carolingians. It seems to have faded from common use, but several of my cousins around my age were still seeing it in textbooks.

It was also applied to North and South Carolingians separately, not just to all people in the Carolinas as a whole.
