This is part of a series 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. While the present volume is not a comprehensive directory of all the inhabitants of Perthshire during the mid-18th-century, it does pull together references on more than 1,200 18th-century inhabitants. Coverage extends to all regions within Perthshire. In all cases, Mr. Dobson gives each Highlander's name, a place within Perthshire (birth, residence, employment, etc.), a date, and the source. In some cases, we also learn the identities of relatives, the individual's employment, vessel traveled on, and so forth.
