This is the sixth volume (seventh 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. For this volume, Mr. Dobson relied on primary source material found in the Public Record Office of Northern Ireland in Belfast, and in the National Archives of Scotland in Edinburgh. He has supplemented those findings with research into secondary sources in the Linen Hall Library, Belfast, and in the library of the University of St. Andrews, Scotland. These are sources, by and large, that Mr. Dobson has not consulted for the previous volumes in this series.
