Comments: In 2004 the Irish Department of Health - the Health Service Executive (HSE) - introduced a computerized system for recording the registration of Births, Deaths and Marriages in the Republic of Ireland. Any record created prior to 2004 has also been transferred to this new electronic State database by scanning the original entries in the Registers for Births, Deaths and Marriages on to the new computerized system. Certificates are now issued based on these records where a scan of the original Register Entry is printed on to Certificate paper.
Any birth registered before the 1 OCTOBER 1997 does not provide the following details:
A surname of the child (it is assumed that the child takes the surname of the Father when he is named on the Birth Certificate or the surname of Mother if the Father is not named on the Birth Certificate).
Any former surname of the Father.
The occupation and address of the mother.
These details are recorded on any birth registered on or after the 1 October 1997.
