Ey up Ed!
Sorry about this: we've got the same Grey Stone (Yorkshire section) twice. One entry as simply 'Grey Stone' and the other as 'The Grey Stone.'
Why do we have the word "the" before any of the sites? - e.g. The Twelve Apostles, or The Swastika Stone?, etc. Can we get rid of it? After all - who's gonna search out any site preceeded by "the"?
