Introduction
The historic counties of England, Scotland, and Wales have been of cultural significance as each county has determined the heritage of the people of the region and the descending diaspora related to every county. While Ireland and the Isle of Man also play large roles, along with Jersey and Guernsey, the primary settlements on Great Britain have also been of significance regarding the situation of a generally Celtic region.
