The most research indicates the bulk of Irish people are descended from
settlers from an Ice Age refuge in the Pyrenees. Check out "Western Atlantic Modal Haplotype" for more info. The terms Celtic, Viking, Norman, English, Scottish are cultural terms and not necessarily biological. Despite what the following answer
states researchers McEvoy et al. found "scant evidence of Scandinavian Y-chromosome introgression in a general Irish population sample". The findings were consistent with a relatively small number of Norse settlers and descendants migrating into Ireland in the period of 800-1200 AD suggesting that Norse colonial settlements might have been largely composed of indigenous Irish.
Another Answer:

If your people are from Dublin, then they are Irish. It will depend on where you are from, like where you were born and live to determine where you are from. You may have Irish ancestry through your people, but if you were not born in Ireland and don't live there, then you cannot fully claim to be Irish, although you will be able to get an Irish passport, if a parent or grandparent is from Ireland.
