The localization of the archetype to Berwickshire is natural because the Greenwood group of ballads (which closely abide by the romance) belong to this area, and because this was the native place of the traditionary hero, Thomas of Erceldoune. Having made his examination, Nelson declared that his assumptions were justified by evidence, deciding in favour of the "eighteenth-century origin and the subsequent tradition of ballad of 'Thomas Rhymer'", a conclusion applicable not only to the Greenwood group of ballads but also to the Brown group. This view is followed by Katharine Mary Briggs's folk-tale dictionary of 1971, and David Fowler.
