This is the fifth volume (sixth part) in a series compiled by Mr. Dobson to identify the Lowland Scots who migrated to Ulster between 1575 and 1725-many of whose progeny may have emigrated to America. As he has for the prior volumes, Mr. Dobson here relies on primary and secondary source material found in Scotland and Ireland. With one or two exceptions, Mr. Dobson has extracted his findings from sources not consulted for the previous volumes, such as the National Archives, London; the Prerogative Court of Canterbury; the Presbytery Book of Kirkcaldy, 1630-1653; the Extracts of the Records of the Burgh of Stirling; and a number of other sources.
