 The county was originally settled by migrants of "Yankee" stock (migrants from New England and the western part of New York who were descended from the English Puritans of colonial New England).With the opening of a rough wagon road to the source of the Tioga River, New England settlers poured over the Allegheny Mountains.Tioga County resembled upstate New York more than it did eastern Pennsylvania, as its population primarily consisted of settlers from New England.
