An ongoing endeavour to make the registers of baptism, marriage and burial from Church of Ireland parishes available in a digital format. The online version is hosted by the Representative Church Body Library, which will periodically introduce new transcripts of parish registers.
At time of writing this project is still very new but Delgany (Glendalough)Co. Wicklow is available along with Newtownbarry, Co. Wexford. Check the index volume in order to find individuals in the registers.
