Larry,
Can't find Somerset? Okay, imagine you are heading towards London from the direction of France, turn sharp left at London and keep going until you bump into Wales, then look downwards and you should see Somerset. Nice county...I was at school there (although I lived in another part of the country), and I can tell you they produce terrific hard cider.
Here is a link to a website on Westbury:

There's no particular reason to think there is any connection between people named Hardwick and the place with the same name.
Gary,
I think they should open a U.S. consulate in Stratford-on-Avon, since 90% of its visitors appear to be American. I've never been there. Mind you, I've never been to Cornwall, or Stonehenge, or the Cotswolds, or the Lake District, or the Scottish Highlands, or Hadrian's Wall either.
