The burial places list is mostly American, this Poets' Graves site is more comprehensive and even lists four Irish poets, Louis MacNeice, Carrowdore, Co. Down, Jonathan Swift, Dublin, Gerald Manley Hopkins; Dublin (Glasnevin) and W.B. Yeats, Drumcliff, Co. Sligo.
On Thursday I visited Swift's resting place in St Patrick's Cathedral, Dublin and tomorrow or Tuesday I hope to say hello to fellow Sligo poet at Drumcliff.
I finally found Raftery's grave near Craughwell on the recent trip to Galway. It's not signposted and easy to miss. His fellow poets and competitors, the Callanan brothers, are buried in the same graveyard.
