This is part of a series of books by David Dobson designed to identify the origins of Scottish Highlanders who traveled to America prior to the Great Highland Migration that began in the 1730s and intensified thereafter. This volume is the second to cover the Northern Highlands, an area that includes the counties of Caithness, Sutherland, Ross, and Cromarty. While this volume is not a comprehensive directory of all people living in the Northern Highlands during the mid-18th century, it does pull together references to more than 2,100 18th-century inhabitants. In all cases, Dr. Dobson gives each Highlander's name, a place name or county within the Highlands, a date (of birth, residence, etc.), and the source. In the majority of cases, we also learn the identities of relatives, the individual's employment, vessel traveled, or other defining characteristic.
