Should it be <i>Giant's Stone</i> or <i>Giants' Stones</i> or <i>Giant's Stones</i>?

Thanks

woops, never noticed- thanks greywether.
Aye- I was a bit confused with the name of the site- after thinking about it some more I think we should go for Tweedsmuir, the name by which the site is referred to in CANMORE and make note (or an AKA) that one of the stones is the Giant's Stone (or Giants Stone as it is referred to twice in the CANMORE entry!)
