You can also try Eneclann the genealogy division of Trinity College. No comment on the research center as I haven't used it myself. They will have the parish records that exist for
the area. Years ago I found the expense of the Wicklow
center to be exhorbitant but after visiting Ireland and doing my own research I can understand now how many hours are required for research. I was also fortunate in that the family I was investigating were Church of Ireland. Their parish registers to 1899 are kept in one place, at their Representative Church Library. I do know RC records are all kept in local custody and most gave access to them being copied by local genealogy centers so there were no so many
tourists wanting parish priests doing research. Only a
few Catholic Diocese are doing their own genealogy research.
You can also try looking for journals produced by Heritage
and Museum Societies for gravestone inscriptions.
