That fits. The Carlingford grouping (around Carlingford Lough) would have come about through monuments like Clontygora, Audleystown, Rockmarshall, Ballymacdermott and one of the Goward tombs. The Goward court tomb was the first one excavated and it surprised them a little - they thought it was a stone circle.

Then of course the massive concentration of them in the west was realised and that, as they say, was that. No more Carlingford group.
