You mentioned Bloomfield Ave in the first post - is this place of death on the cert, or just a residence ?
If it's the place of death then the district details should help narrow down which Bloomfield Ave. the death took place at. On the cert there should be be district details, usually at the top of the form - part of the section with Dublin South, Co. Dublin etc. The clue will be the sub-district - which will be something like South City No. 4, Donnybrook 2 etc
It's also worth checking the informant - this can be a clue if it took place in a hospital or institution, although I think the place of death would have stated Donnybrook hospital if the death was there...
