This is a really good video, filmed for Our State magazine, the official publication for North Carolina. I subscribe to the digital edition having seen it when on holiday back in July.
The interview here is done by Bob Crawford, the bass player with the wonderful Avett Brothers who are from Concord in North Carolina - a town so-named because it was the agreed location for the 'county seat' between the German Lutherans and the Scotch-Irish Presbyterians. Bob Crawford and David Childers have a side-project band called The Overmountain Men, where they put stories from American history into song (interview here). As Childers says: "“My people were from back up in the hills, where the Overmountain Men came from. Scotch-Irish savages.”
This interesting book from 1940, a historical travelogue, traces the Crawfords from Scotland to Ulster, then across to New England in 1718, and then onward into the rest of America.
