It's been a long time since I ventured there.
I was pleasantly surprised [ stunned?] to find this brilliant web site :
Lots of records and scans of the registrars books and it's FREE!
I've been furiously downloading several branches using family lore and the 1901/11 census information, mainly events from 1880's-1910's, and so far I'm just in Fermanagh and Down.We are pleased to advise that in early 2019, an additional 2 years of records of births, marriages and deaths will be added to the www.irishgenealogy.ie website. The marriage Index data along with additional images will also be updated for the years 1864-1869 inclusive. The years covered by the release of the historic records of Births, Marriages and Deaths after this update will be;
Births: 1864 to 1918 Marriages: 1864* to 1943 Deaths: 1878* to 1968
I haven't got my head round what is or isn't there or how far the records go, but I've certainly got a lot more I started with.
I've got lots of info from Enniskillen castle about various other resources that I've still to investigate.
