How to Use IrishGenealogy.ie
for Irish Family History

By Brittany Warren · Published 14 October 2026

If you are looking for an Irish birth, marriage or death, I would try IrishGenealogy.ie early on. It is free, and for many civil records you can open an image of the register entry rather than make do with a search result. The difficulty usually comes when a familiar name produces too many results, or none at all.

I will use a made-up example, Pat Sullivan of County Kerry, to show how I would search. The same habits apply as in my guide to the Antenati registers in Italy: check which records were kept, work from what you already know, and read the entry once you find it.

What records are on IrishGenealogy.ie?

IrishGenealogy.ie is run by the Irish government. Its two searchable collections are civil registration (births, marriages and deaths) and selected church registers (mostly baptisms and marriages, with some burials). You can search and view the records available there without a subscription.

You will see different kinds of results. An index entry might give you a name, year and registration district; a transcription gives you details typed from a church register; an image shows what the clerk or priest actually wrote. If an image is available, open it. The index may have missed something.

Civil records: the current date ranges

*Civil registration of non-Catholic marriages began in 1845. Catholic marriages, births and deaths were registered from 1864. Deaths in 1864–1870 are in the index, but the corresponding register images are not yet in this collection. Images can also be missing for individual later entries.

The most recent update added births from 1925, marriages from 1950 and deaths from 1975. The usual cut-offs are 100 years for births, 75 for marriages and 50 for deaths. Those years become searchable when the site publishes its annual updates, not necessarily on the anniversary of an event.

The church records cover particular areas

The church search is easy to misunderstand. It does not contain every Catholic or Protestant parish in Ireland. The main collections are listed below, but even within a named diocese the years can differ from parish to parish.

I would check the parish coverage list before searching for a baptism. It tells you which registers are included. For instance, the Carlow records here are Church of Ireland registers; they are not a searchable set of every Catholic parish in County Carlow.

How many records are there?

For an idea of the size, these are the figures the government published on 1 March 2022. They are dated figures, as more years have been added since.

Together, that comes to 15,667,904 civil entries in the 2022 announcement. It is not a current live count. One person can appear in a birth, a marriage and a death entry, so the total should not be read as a count of individuals.

There are church entries on top of this. I have not found a comparable, current figure published for the complete church collection. When I am searching, the useful question is whether the right parish and period are present.

Before searching, find one solid clue

Start with the most recent record you trust. If your great-grandfather died in England in 1940, find his death or marriage record, look for a birthplace, and work back. A remembered county is useful, but I would not use it to choose a random baptism in 1840. IrishGenealogy.ie has a good introduction to starting your family history, and the National Library makes the same point about beginning with what you can verify.

Write down the name, an approximate birth year and whatever you have for the place. If you know a parent, spouse or sibling, add them as well. The marriage of an Irish emigrant in Britain or America can be particularly handy if it names a father. I explain other ways of joining up the two sides of an emigration in my transatlantic research guide.

Kerry is a county, not a registration district

Irish place names can be confusing at first. A townland is a local land division, a civil parish is an administrative area, and a Catholic parish may cross civil-parish boundaries. A civil registration district is another area again. If a birth appears under the Tralee registration district, that does not mean the family lived in Tralee itself.

Copy the place exactly as it appears on the document. For an unfamiliar townland, I often check Logainm and John Grenham’s place-name pages. A family story saying “Kerry” is a starting point. I would keep the county search fairly broad until a record gives me somewhere smaller.

Searching for a civil birth, step by step

Open the IrishGenealogy.ie search. At the time of writing, you can choose Civil Records, Church Records or All Records. Some older instructions refer to a different screen, so follow the field labels on the website if they have changed.

1. Start with a birth search

   For Pat, I would select Civil Records and Birth. Civil birth registration began in 1864, so an estimated 1878 birth is within the right collection. If I were looking for someone born in 1850, I would start by finding their parish registers instead.

2. Keep the first search loose

   I would enter Patrick Sullivan and try 1875–1881. I would leave Exact name matches only unticked. The birth year comes from a later document and could be a few years out.

3. Choose Kerry from the location suggestions

   Type Kerry and click the appropriate dropdown suggestion. Leaving plain text in the location box may not apply the filter. If Kerry is only family hearsay, repeat the search without a location too.

4. Get past the access form

   The civil search can ask for your own name, an acknowledgement and a CAPTCHA. These are about access to the register, not details about your ancestor. You do not need to pay to use the online images.

5. Look at more than the first result

   Check the year and district of each plausible Sullivan birth. Open the record image where there is one. I would make a note of at least a couple of candidates before deciding that I had found Pat.

6. Then change the search

   I would try Pat Sullivan, then O’Sullivan, then Sullivan with no forename. Only after that would I widen the years or remove Kerry. Changing one thing at a time makes it easier to see why a new result has appeared.

The same goes for exact day and month fields or a parent’s name. If the detail is a guess, leave it out. Very narrow searches often fail because one box contains information the index does not hold.

Try Pat, Patrick, O’Sullivan and Sullivan

A person can appear under several names without ever changing their name formally. Pat is common for Patrick, Jas for James, Jn for John and Wm for William. Catholic baptism entries may use Latin: Jacobus for James, for example. The GRONI guidance gives examples of abbreviations, and IrishGenealogy.ie has a separate page on church searches.

You can use an asterisk as a wildcard. For instance, M*Carthy can bring back spellings with different letters between M and Carthy. I would still run separate searches for MacCarthy and McCarthy if I had trouble finding the family. Keep a county or sensible date range in the search, or a wildcard can return an enormous list.

For women, think about which surname would have been used at that date. A marriage entry may use her maiden name; a later death may be under her married name. A widow who remarried might appear under her first husband’s surname. Also try a surname-only birth search: some children were registered before a given name had been chosen.

Similar spellings are a reason to inspect a result, not a reason to attach it to your tree. Two different Sullivan families could be living a few townlands apart.

What I look for in the original entry

Open the image, find the right line and read across the page. The name is only one column. In a birth entry, for example, the address or townland and mother’s maiden surname may be what separates two children who share a name.

These are typical fields rather than a promise that every clerk filled every column.

Back to Pat: suppose one birth names a father Michael Sullivan, labourer. That is worth keeping. But if the mother’s name and townland do not agree with later records, I would keep looking. I would also check births of possible brothers and sisters at the same address. A father’s occupation may change; an entirely different set of parents needs a better explanation.

One easy mistake is to copy the date at the top of a register entry as the birth date. It may be the registration date. Read the field headed “Date and Place of Birth”. The same care applies to baptisms and burials: those ceremonies may take place after the event.

Searching the parish records

For a baptism, check the church coverage first. Then select Church Records and Baptism, and begin with the surname and a rough span of years. If the parish is uncertain, do not narrow it to a village simply because the family lived there later.

Read the role beside each name. A search result may mention John Murphy because he was a godparent, witness or father, not because John Murphy was the person baptised. The site’s search overview explains why names of different people can turn up in the same result.

If there is an image, read it alongside the transcription. A priest’s handwriting can be difficult, and typed names are sometimes wrong. I also note the godparents or marriage witnesses. If the same people turn up at the baptisms of three children, that is a good lead for another search.

For Church of Ireland or Presbyterian families, find out where that parish’s registers are held and which years survive. A Catholic parish and a Church of Ireland parish with the same place name may have different boundaries. Also, many Catholic parishes did not keep burial registers, so you may find baptisms and marriages but no burials at all.

What was lost in the Four Courts fire in 1922?

On 30 June 1922, during the Irish Civil War, the Public Record Office of Ireland at the Four Courts in Dublin caught fire following an explosion. The building held census returns, wills and probate papers, court records and many Church of Ireland parish registers deposited for safekeeping. Much of that material was destroyed.

The original census returns for 1821, 1831, 1841 and 1851 were largely lost in the fire, though fragments and copies survive. You may also hear that the censuses of 1861, 1871, 1881 and 1891 were destroyed. Those losses occurred before 1922, for different administrative reasons.

The General Register Office kept its civil birth, marriage and death registers separately, which is why you can still look up an 1878 birth on IrishGenealogy.ie. The 1901 and 1911 censuses survived too, as did many Catholic registers and Church of Ireland registers held outside the Public Record Office.

For material that was held in the old Public Record Office, try the Virtual Record Treasury of Ireland. It brings together surviving documents, duplicates and copies of records that no longer exist in their original form.

If the search turns up nothing

I usually go back to the search form and strip it down. These are the things I check, roughly in this order:

1. Right collection? A Catholic marriage in 1850 will not be in the civil marriage register. Check whether the church parish and year are covered.
2. Name too exact? Untick exact matching; try Pat/Patrick and O’Sullivan/Sullivan, then the surname alone.
3. Year too narrow? Someone recorded as 60 at death may have been 57 or 63. Try several years either side.
4. Wrong location? Clear the county or registration district and search again. Do not forget to select a location suggestion when you put one back.
5. Too many boxes filled? Remove the day, month, parent or mother’s surname if you cannot be sure the index contains them.
6. Can I find a brother or sister? Their birth records may give the mother’s maiden name and a townland, which could settle the search for your ancestor.
7. Does an index result exist without an image? Note the reference. An image gap or loading problem is a different issue from a missing registration.

For a missing image or broken link, check the site’s FAQ. You may need to order the entry from the relevant General Register Office if only the index is available. A page that will not load says very little about whether the original register survives.

If the relevant parish register begins in 1845 and you need a baptism from 1820, no change of spelling will fix that gap. I would move to a different source, or try to find the same family through a marriage, a sibling or a later address. There is more on this in my brick-wall research guide.

Where I go next

All Records searches this site’s own collections. It does not search the National Archives, National Library and every other Irish record website together. Depending on the period, I would try:

• Census records. The National Archives has the 1901 and 1911 censuses. It also published the 1926 census for the 26 counties online on 18 April 2026. Check who was living in the same household, the occupation, and whether the address agrees with a civil entry.
• Property records. Griffith’s Valuation and the Tithe Applotment Books may put a surname in a particular townland before the surviving complete censuses. They record occupiers and land, not everyone in a family. The National Library’s further research page has links to these sources.
• Parish registers elsewhere. Try the National Library’s Catholic images. For Northern Ireland, check GRONI and the Public Record Office of Northern Ireland. For Church of Ireland registers, consult the surviving-register guides.
• Newspapers and overseas records. A death notice can mention a brother or a home village. If your ancestor left Ireland, look at records made after the move as well. I have guides to newspaper archives and transatlantic research.

IrishGenealogy.ie has a Get Help page with research guides and links to the National Library and National Archives. It is handy if you are unsure which archive holds the next record.

Keep enough detail to find the record again

If I find a possible match, I save the image or a usable reference and write down the registration district or parish, year, entry number and link. I also note the date I looked at it. If handwriting is hard to read, I put a question mark beside the uncertain word. Do the same for searches that produced nothing: write down the name spellings, places and years already checked.

For Pat, I might write: “Two Patrick Sullivan births found in Kerry, 1877 and 1879; one has father Michael, labourer; need mother’s name from later family evidence before choosing.” That note will be more useful next month than a screenshot labelled “Patrick Sullivan”.
