The one from Diarmuid agus Grainne, that is! To mark Heritage Week, a local history group organised a series of talks at the old graveyard at Murragh, Enniskeane, today. One of the talks claimed that Diarmuid was buried here.
I think it would take a serious DNA project to test that one!
Among the attentive attendees were these two neighbours.
