Your post was very sketchy: no B/M/D dates, no parent's names, no placenames.
There are two online databases for Irish B/M/D records. The largest (a pay per view) can be found at ROOTSIRELAND.IE. It has (most) surviving church and civil B/M/D records for 27 of Ireland's 32 counties. The second is FREE. However, it is limited to surviving church B/M/D rcds for Co. Kerry, parts of Co. Cork, and Dublin City.
Both databases' managers are in the process of transcribing more county records, and adding to the existing databases as more records/sources are discovered.
Try to find more precise data, then visit one or the other database.
