John, it sounds as though most people believe the solution is to add a new category rather than change one. You can add either Scottish folk or British folk - and put the link there too (because although not exclusive of England or Scotland - it fits in both).
When I put the link up I didn't mean to open a can of worms or insult anyone's nationality (two generations back my family is from Arbroath). I was just trying to point people to a resource and chose the only category at the time that seemed appropriate.
