 The term Scots-Irish, though used periodically during the 18th century to describe the Irish Protestants and their descendants who migrated in their thousands to the Appalachian frontier in the colonial period, is a term that achieved widespread usage in the United States only in the early decades of the 19th century. And I know it was a long time ago that we had our lecture on the Scots-Irish, but I've just put this slide up here as a reminder of the volume of those migrations and who they were.
