Just to point out that the registers are freely accessible at https://registers.nli.ie/, but not searchable.
Findmypast, RootIreland, Ancestry have searchable access to the registers, with transcriptions - not all transcriptions reliable. If you find links to your ancestors you can check the image on NLI without having to register with any of the paid up sites.
