Cemetery Location, advice

Hi

I'm going to stay in Pembrokeshire in a week or so and I have two cemeteries on the top of my wish list to visit. The first is Ramah Cemetery, Brynhenllan which I think I can find ok, the other is Macpela Dinas, it's that one I need help with. Can anyone give me a map reference for this one.

I will be staying near Molygrove.

Regards
Colin.
