I'm confused.
Checking out what I can see on the way to the ferry later this month, I'm checking out The Ancient Stones of Wales by Barber and Williams (1989 edition).
In the gazetteer, the Lady Stone (on TMA as Ty Meini http://www.themodernantiquarian.com/image.php?image_id=14578) is shown as being at SN008388, which the ref given for Parc Cerrig Hirion (which isn't mentioned in the book).
Can anyone (Kammer?) clarify which is which for me please?
