The best history of the Scotch-Irish of colonial Pennsylvania ever written, Dunaway's classic is indispensable to the genealogist because it outlines the circumstances behind the settlement of Lowland Scots in Ulster, their life in that Province for two or three generations, and the reasons for their emigration to America, further tracing the important migratory movements of the Scotch-Irish from Northern Ireland to Pennsylvania, and from Pennsylvania down the foothills of the Appalachians through the Great Valley of Virginia to the Carolinas and Georgia.
