Birth registration in Ireland (including Northern Ireland) began in 1864.  The indexes,  you find on this site, are the 1st step of a 2 step process in finding a birth record registered in Ireland.  The Index will give you a full name, the registration district where the birth was registered and then the volume and page number where you can locate the record.

All of the 1864 Index is being transcribed and going online as a project led by the Ireland GenWeb Project.  If you would like to help, .

The following people helped transcribe the K's:  Jim Buckley, Bob, McConihe, Patricia McGill, Mary Devlin, KellyAnn Binari, Diane Culhane, Margaret Minoughan, MaryPat Carey and Pat Connors

NOTE:  The Index is being transcribed from the Family History Film #0101041.  While the film is in fairly good condition, there are pages that are very light so there may be some mistakes in transcription.  Some numbers are hard to define, especially  1 and 4.  Sometimes, you will find ? when we have had a problem deciding exactly what was typed.  Sometimes, a number is typed in error.  Therefore, you should refer back to the film, if you think you found a record you would like to see before ordering the record or checking out the record's film.
