The logical thing to do is to simply take a map and plant the point firmly on your residence, then circumscribe it in such a way that the radius includes all that you favor as a part of the British Isles.

This will give you what you want, and, if you describe your circle properly, it will allow others to replicate and verify your work.


This idea is loosely drawn from a book I once read called, "How to LIe with Maps"--
