In this volume Mr. Dobson introduces the researcher to little-known source materials–the Services of Heirs and the Register of Testaments of the Commissariat of Edinburgh. From the Services of Heirs he extracted all references to North American residents who inherited land in Scotland, and also to Americans who left land in Scotland. From the Register of Testaments he provided abstracts of the testaments of all North American residents who chose to have their wills registered in Edinburgh. All of this data serves to confirm a relationship between the inheritor and his ancestor.
