'mythology' of the Scotch-Irish, James Leyburn provides an absorbing account of their heritage. He discusses their life in Scotland, when the essentials of their character and culture were shaped; their removal to Northern Ireland and the action of their residence in that region upon their outlook on life; and their successive migrations to America, where they settled especially in the back-country of Pennsylvania, Virginia, the Carolinas, and Georgia, and then after the Revolutionary War were in the van of pioneers to the west.
