Back a while ago, I mentioned a book here called American Nations by Colin Woodard, which was about different regional cultures in North America, and some people were interested in it. The bibliography of that book referenced some other titles about NA regional cultures; and I recently picked up and read one of these titles. It's called Albion's Seed: Four British Folkways in America, by historian David Hackett Fischer. The book is about 4 of the groups who originally founded the American colonies--the Puritans in New England, the Quakers in Pennsylvania, the Cavalier colonists of Virginia, and the borderlanders (often called the Scotch-Irish) who settled Appalachia. The book is a tome at 900 pages and it took me a while to read it, and some might find it a bit academic, but I have to say that I highly recommend it if you're interested in the subject matter, it's really good.
