Cheers Mike !. Oddly enough my atlas(quite a good close-scale one), did have said place listed in the index but it was on Anglesey, so I discounted it. Rather frustrating now to see that your one IS also in my atlas, but they couldn't bother to list it in the same index. One of my pet-hates !!

So a beautifull place.
