Free Irish Genealogy Records: What Is Free, and When RootsIreland Is Worth Paying For

You know your great-great-grandfather came from Cork, or Mayo, or somewhere near Belfast, and you know roughly when he left. You type his name into a search box and three different sites offer to show you the baptism. One wants €15 for a day. One wants a subscription. One is free and shows you a page of handwriting with no name index at all.

Most guides answer this with a list of the ten best Irish genealogy websites, free and paid mixed together. That framing hides the useful fact. The core Irish record sets, the civil registers, the Catholic parish registers to 1880 and the surviving censuses, have been published free by the Irish state or its national institutions, and much of what the paid sites sell is a faster route into those same records.

So the question is not which site is best. It is which record you need, who holds it for free, and whether the paid shortcut saves you enough time to be worth it.

The short answer. Irish genealogy is unusually free. The Irish government's irishgenealogy.ie publishes the General Register Office's civil births from 1864 to 1925, marriages from 1845 to 1950 and deaths from 1871 to 1975, free. The National Library of Ireland publishes images of the Catholic parish registers of the majority of parishes in Ireland and Northern Ireland up to 1880, free, and Findmypast indexes those images free. The National Archives of Ireland publishes the 1901 and 1911 censuses free, and on 18 April 2026 it added the 1926 census. RootsIreland, the main paid site, sells transcripts of church registers at €15 for a day or €225 for a year, and it is worth paying for in specific cases: a register that is hard to read, a search after 1880, a common surname where its variant search saves you hours, or a non-Catholic family. For areas now in Northern Ireland, civil records are pay-per-view through GRONI at £0.50 a credit.

The free records are split by record type, not by site quality

The single most useful thing to understand about Irish records online is that each free site holds one record type, because each one belongs to the institution that holds the originals.

The irishgenealogy.ie site is run by the Department of Culture, Communications and Sport, and its own record-sources page is a useful map of what is online and where. It is worth reading once before you pay anyone.

The civil records move forward every year. The site says that, for data protection, births become available when they are over 100 years old, marriages over 75 and deaths over 50, and that each year another year of records is added. So the date ranges in the table above are as of October 2026, and next year each will move on by one.

Marriages start earlier for some couples than for others. The same page notes that non-Catholic marriages were registered from 1845 and Catholic marriages from 1864. If your family were Catholic and married in the 1850s, there is no civil marriage record to find, and the parish register is the record.

The Catholic registers are free three times over

The National Library describes church registers of baptism and marriage as the single most important source for family history before the 1901 census, so it is worth understanding exactly what exists.

The National Library of Ireland's account of its own project is short and specific. In 1949 Edward MacLysaght, then Chief Herald of Ireland and Keeper of Manuscripts, offered the Library's help to preserve the Catholic Church's parish registers. Every bishop took the offer up. Filming began diocese by diocese in the 1950s and took about 20 years, and because civil registration was not reliably kept for some years after 1864, the Library filmed up to 1880. The result was microfilm of more than 3,500 registers from 1,086 parishes. In 2014 the Library's board approved putting the images online free, and the site at registers.nli.ie now holds approximately 373,000 of them.

The images are free, but they are not indexed. The Library's site lets you choose a parish on a map and page through its registers. It is the original evidence, in the original hand, and nothing stands between you and it except the reading.

There is a free index too. On 15 March 2016 Findmypast announced that it had indexed the Library's collection and that the registers were free to search and view forever, describing more than 40 million names from over 1,000 parishes covering 97 per cent of the island. Ancestry publishes its own index to the same images, titled "Ireland, Catholic Parish Registers, 1655-1915", and its collection page says the index was built from approximately 367,000 images made available free by the Library, and that the images are free on Ancestry as well. That page does not say whether searching the index needs a subscription, so check before you rely on it.

So for a Catholic baptism or marriage before 1880, you have the original images free from the Library and a free index pointing at them, with a second index on Ancestry. Two indexes made by different teams from the same pages are also a check on each other: if one misreads a surname, the other may not.

Know where the registers stop. The Library says start dates vary from the 1740s and 1750s in some city parishes in Dublin, Cork, Galway, Waterford and Limerick, to the 1780s and 1790s in counties such as Kildare, Wexford, Waterford and Kilkenny, and that registers along the western seaboard generally do not begin until the 1850s or 1860s. A family from the west coast who emigrated during the Famine may have left before their parish began keeping a register at all. That is not a failed search. It is a fact about the parish, and worth recording as negative evidence so you do not search it again.

What RootsIreland sells, and when it is worth it

RootsIreland is run by the Irish Family History Foundation, which describes itself on its home page as the coordinating body for local genealogy centres. Those centres, it says, work with volunteers, clergy and government agencies to build and maintain databases of local records, and the site sells access to the result.

On 6 October 2026 its subscription page listed four options: €15 for a day, €30 for a month, €125 for six months and €225 for a year. It says a one-day purchase is deducted from a longer subscription if you upgrade within 30 days.

What it holds, in the words of the irishgenealogy.ie sources page: transcripts, without record images, of most of the Catholic records on the island of Ireland, for areas other than those already on irishgenealogy.ie. The same page adds the important limits: only a small proportion of records are transcribed for counties Donegal, Monaghan and Wexford, and none of the transcribed records for Clare are online. It also has Church of Ireland, Methodist and Presbyterian transcripts for some counties.

In our judgement, it is worth paying for in four situations.

When the free register is hard to read. RootsIreland's church records help page says its transcripts were compiled from locally held registers in the majority of cases, not from the Library's films, and warns that there will be differences between what it holds and what is on other websites. On a faded or tightly written page, a transcript from a different copy is a second reading you would otherwise have to make yourself.

When you need a baptism after 1880. The same page says the Library's microfilms cover the period up to 1880 or 1881, while its own records go to at least 1899, and that for the years after 1880 its transcripts cover the majority of counties.

When the surname is common. RootsIreland advertises a surname variant search that finds every form of a name in one go, giving Brien, O'Brien and Bryan as its example. For a very common surname, that can save a great deal of searching.

When you need a non-Catholic register. The Library's free collection is Catholic only. For a Presbyterian family in Ulster, the paid transcripts, or the free microfilm at the Public Record Office of Northern Ireland, are where you go.

It is not worth paying for when the free index has already found the baptism. If Findmypast's free index gives you a name, a date and a parish, and the Library's image confirms it, a RootsIreland transcript of the same entry adds a second opinion and nothing else. Buy a day, not a year, and only after you have exhausted the free indexes for that parish.

One thing not to claim, because it is not published. We looked in October 2026, on RootsIreland's church records help page and subscription FAQ, on irishgenealogy.ie and in Findmypast's announcement, for any figure on how much of RootsIreland's Catholic transcription overlaps with the free indexes of the Library's images. We found none. RootsIreland says only that some of its records are not in the Library's registers, and that some registers were never microfilmed. You find out for your parish by searching both.

One more inconsistency is worth knowing, because it tells you how carefully to read headline figures. On the same day, RootsIreland's home page described 32 local genealogy centres and its subscription page described 34. Both pages say the site holds more than 23 million records.

The 1926 census opened in April 2026, and older guides miss it

If your family was still in Ireland after independence, this record set only went online in April 2026, and some of the advice you will find, including the example below, has not caught up.

The National Archives of Ireland released the 1926 census on 18 April 2026. Its page on the release describes almost three million individual entries, each with more than a dozen pieces of information, around 45 million data points in all. It is searchable by name or by place.

It is not finished, and the Archives says so. The same page explains that the first release focuses on names, surnames, streets and townlands, and that the free-text fields, occupation and employer, will become searchable in a later phase because they were written in people's own words and need manual transcription. It reports approximately 3,000 people missing from the transcription, around 0.1 per cent of everyone enumerated, mainly in Dublin, Limerick, Wexford and Kilkenny, and says data issues are particularly apparent in Donegal. It also says the household returns for most of the missing people have been digitised and can be sent to researchers as PDFs.

The practical point is simple: a failed name search in the 1926 census in 2026 is weaker evidence than a failed search in 1911. If you cannot find someone, search by place using the map, and search again after the next update.

Why there is no census between 1851 and 1901

The gap is why RootsIreland, for example, has a whole search category of "census substitutes".

The FamilySearch Research Wiki's page on Irish censuses explains that the censuses of 1821 to 1851 were mostly destroyed in the 1922 fire at the Public Record Office in Dublin, and that the censuses of 1861 to 1891 were destroyed by the government some time after the statistics had been compiled from them. The Virtual Record Treasury of Ireland, which is reconstructing what was lost, describes the moment: early in the afternoon of 30 June 1922, during the fighting at the Four Courts, an explosion shattered the Record Treasury and the old, dry records burned.

The same FamilySearch page, read on 6 October 2026, still says that all Irish censuses taken since 1911 are not available. That was true until April. It is a small example of why an old guide is a poor guide to Irish records in 2026.

What fills the gap is free too. Griffith's Valuation, the property survey published county by county between 1847 and 1864, is on the Ask About Ireland site with transcripts and images. The Tithe Applotment Books, from about 1823 to 1838, are free to search on the National Archives' site. Neither lists a household. Both name the person who occupied or paid for a piece of land at a date, which is often exactly what you need to choose between two families of the same name in neighbouring parishes, and is the step that finding an immigrant ancestor's town of origin usually turns on.

Northern Ireland works differently

If your family lived in what is now Northern Ireland, the civil records come from a different office on different terms.

The General Register Office for Northern Ireland, GRONI, holds births and deaths registered from 1 January 1864 in what is now Northern Ireland, non-Catholic marriages from 1 April 1845 and all marriages from 1864. Its own introduction to its records sets out the prices: a basic index view is free, an enhanced index view costs one credit, and viewing the full record or image costs five credits, at £0.50 a credit. So a single register image costs £2.50. A copy certificate costs £8.

For church records, the irishgenealogy.ie sources page says the Public Record Office of Northern Ireland has freely available microfilm copies of almost all surviving records of all denominations for areas now in Northern Ireland, and also holds records for the border counties of Donegal, Cavan, Leitrim, Monaghan and Louth. PRONI says that even the church records it has digitised, over 500 records from 70 churches so far, are accessed onsite in its search room.

How to decide, by what you are actually looking for

The ranking below is ours, so treat it as judgement rather than any institution's advice. For the wider question of what archives charge and why, see what archives charge to copy a record.

A Catholic baptism or marriage before 1880: free. Search Findmypast's free index, then open the image on the National Library's site.

A civil birth, marriage or death in what is now the Republic: free on irishgenealogy.ie, within the 100, 75 and 50 year limits.

The same in what is now Northern Ireland: GRONI, pay per view. Use the free basic index first, then pay £2.50 only for the entries you need.

A household in 1901, 1911 or 1926: free on the National Archives' site.

A family in the 1850s with no census: Griffith's Valuation and the Tithe Applotment Books, both free.

A hard-to-read parish, a baptism after 1880, a very common surname, or a non-Catholic family: this is where RootsIreland earns its fee. Buy one day, plan your searches before you pay, and upgrade only if the day proves the county is well covered.

If you are weighing the general-purpose subscription sites against the free ones, the same logic applies as in MyHeritage versus FamilySearch: check what the free version already gives you before you pay for an index of it.

What KleioBase does with Irish records, and what it does not

Disclosure, since we sell a tool.

KleioBase is an AI research companion that turns scattered historical records into one connected family archive. It is not a record site and holds no Irish records. It works on the ones you have already found, from whichever of the sites above you found them on.

That suits Irish research, because an Irish family is often spread across four or five sites. You can upload the baptism image from the National Library, the civil marriage from irishgenealogy.ie, the 1911 household and a page of Griffith's Valuation. The people, dates, places and relationships on each are extracted and linked across all of them, so the same Patrick in the baptism, the marriage and the census becomes one person with three sources rather than three search results. When the baptism and the census disagree on a birth year, both claims stay visible against their own record. On the Researcher plan and above, a person's Expected records panel lists the Irish censuses they should appear in but do not yet, and the Research Companion can search the public web for the archive most likely to hold a record you are missing.

Now the honest limits. Three of them.

It recognises Northern Ireland by name only. Expected records suggests the 1901, 1911 and 1926 censuses, and skips 1926 for Northern Ireland, whose own 1926 returns do not survive: Queen's University Belfast's policy blog puts the first extant Northern Ireland census at 1937. It knows a place is in Northern Ireland only when the place names a Northern Ireland county, Belfast, Derry, or Northern Ireland itself. A place written as "Lisburn, Ireland" still gets a 1926 target it should not.

It cannot search inside any of these sites. It reads the public web, not the databases behind a search box or a login, so it cannot run your search on Findmypast, Ancestry, RootsIreland or GRONI for you.

It does not know which source to trust. It keeps a register entry and a transcript of the same entry as two claims and shows you where they disagree. Deciding that the image outranks the transcript is your call, and it should be.

Where to start, before you pay for anything

Take one ancestor and write down what you know: name, county, a rough birth year, and whether the family was Catholic.

Search the free indexes first. Findmypast's index to the Catholic registers for the baptism, irishgenealogy.ie for any civil record within its date limits, and the National Archives for 1901, 1911 and 1926.

For every hit, open the image. On the National Library's site, find the parish and the year and read the entry yourself.

Then write down what you could not find, and why: a parish register that starts after the birth, a census year that was destroyed, a county RootsIreland barely covers. That list tells you whether a paid day on RootsIreland, a GRONI image, or a trip to a reading room is the next step.

The Library's staff who carried registers from every diocese to Kildare Street for filming in the 1950s, and the parish volunteers who transcribed them again at the local centres, were working on the same problem from opposite ends. Because of them, much of what you need is already free. The money is for the parts the free work did not reach.
