Hi Vera, yours is not a silly question like you thought. Irish passport holders looking to relocate in Spain are inside a big tent wishing to live in a smaller tent within. Currently, you are outside of the big tent.
Irrespective of money, freedom-of-movement within the EU will probably be your main issue. Before you pay a penny to reside in Spain you'll need an NIE number (available through the Spanish Embassy in the UK @ £6/£7). You can get this easily no matter what nationality or passport you have. If you do this you'll save yourself about £100 as if you decide to allow your solicitor in Spain to do it, you'll get charged.
Irish Passport:- If you can get one, get it. Even if you father's details cannot be found get a picture of his grave-stone with names and dates shown as clearly as possible. The local authority or church-yard owner may have details of whoever was buried there and may be able to trace relevant identification numbers etc. If your father's details cannot be found* (likely) you may have to sign an affidavit regarding his details. It's no big deal (sorry if I sound flippant), but the Irish authorities are pro-active in getting as many passports issued as possible especially to people in the UK.
Five years ago we could renew our Irish passports within a five working day turnaround; currently it's taking 6 - 8 months. Perhaps this explains the level of interest in obtaining an Irish Passport? I understand the processing of Irish passport applications for residency in Spain is an express-train route to living there.
*Registration of births pre 1951 was no great issue in Ireland. Childrens' Allowance (Family Allowance) came into being pretty late in Ireland and there was not much monetary gain registering births until later. Many births were registered years later than the birth date. For the record most Irish births occurred at home rather than in a maternity hospital. In the 1930's, 1940's, 1950's, 1960's, 1970's there was mass emigration from Ireland to the UK. Many Irish (including me) emigrated to the UK immediately after finishing school. Work was plentiful in the UK and the pay was better than in Ireland. Things were worse again in rural Ireland and there emigration to the UK was a near certainty for most.
Note:- In 1970's (and before) Ireland, people were not issued with PPS (Social Security) numbers until they started work in Ireland. It is likely your father had his first real job in the UK and so he would not have been issued with an Irish number. I should add that many who worked especially in rural Ireland back then did so on a cash-per-work basis. PAYE (as in income tax) didn't come to Ireland until the late 1950's and even then not many were registered.
Above is much a large part of the Social History of Ireland from 1921 - 1971.
