Are you one of the millions of family historians with ancestry from the Emerald Isle? Then you’ve got the “Luck of the Irish!” Ireland is one of the most popular genealogy research topics, and there are tons of resources available online- but don’t get overwhelmed! The keys to unlocking your family’s Irish roots are understanding the research challenges, creating a plan, and locating the records you need.

This article features some of the best Irish genealogy sites to help you begin the journey to discovering your Irish ancestors!

1. Ancestry

Ancestry is a great option for Irish research. It’s important to know that Ancestry is a paid subscription site, and a World Explorer membership or higher is needed to view non-U.S. record collections. Ancestry does offer a free trial- and check out this article that provides an in-depth review of Ancestry offerings.

Ancestry’s Ireland family history research page provides a list of their Irish records collections, plus links to additional resources. The Irish Records page provides more information about Ancestry’s collections and divides them into categories (census, military, vital records, etc.). You can also learn about and search within Ancestry’s Irish Records Index and the Irish Records Extraction Database.

Additionally, check out Ancestry’s Discover the Irish in youpage, which provides a research video tutorial, records search, and information about their Ireland collections-plus you can learn about Ancestry DNA testing and how it could help your Irish research. The Ancestry Support Center also provides tips for finding Irish records and discusses record loss.

2. MyHeritage

MyHeritage is another subscription website that has its own collection of Irish genealogy records. Like Ancestry, MyHeritage has subscription tiers, but does offer a free trial- check out our review of MyHeritage for details.

Learn more about MyHeritage’s Irish collections and give their search tool a try, plus learn some facts about Irish heritage and how MyHeritage’s DNA offerings could help your research.

3. FamilySearch

FamilySearch is operated by The Church of Jesus Christ of Latter-day Saints and is one of the most well-known free genealogy sites.

A good place to start is the FamilySearch Wiki, a virtual encyclopedia of genealogy topics. The Ireland Genealogy page is full of research information, links to each Ireland county, a list of video tutorials, an interactive map, and much more!

This Wiki page also notes an important aspect of Irish research- after 1922, Ireland was divided into Ireland (its own country) and Northern Ireland (the 6 northernmost counties which became part of the United Kingdom). If you are researching ancestors that immigrated from Northern Ireland in the 20th century, be sure to review the Northern Ireland Genealogy Wiki.

Other helpful Ireland Wiki pages include Ireland Research Tips and Strategies, which addresses the challenges in researching Irish ancestors prior to 1864- many records prior to this date were destroyed, and special research techniques may be needed to locate your ancestors. Also check out the Ireland Genealogy Websites Wiki for a fantastic list of resources. The Ireland Online Genealogy Records Wiki lists the Irish record collections available on FamilySearch, as well as on other websites- be sure to bookmark this page.

The Ireland Research page on FamilySearch also provides a list of relevant collections, provides a link to helpful Irish research videos in the FamilySearch Learning Center, and allows you to search through their indexed Ireland records- all in one place. The FamilySearch Blog also provides tips for finding Irish vital records.

5. RootsIreland

Maintained by the Irish Family History Foundation, RootsIreland contains over 22 million records, including an extensive collection of Irish Catholic records. They also have other record sets including passenger lists, and Griffith’s Valuation records. You can narrow your records search by county, making it easier to find the information you need. RootsIreland is a subscription website, with options ranging from 1-day to 12-month.

6. National Archives of Ireland

The National Archives Genealogy Website offers a rich repository of historical data including census records from the early 19th to early 20th centuries, Tithe Applotment Books from the 1820s to 1830s, Soldiers’ Wills, and various records concerning wills, marriage licenses, and shipping agreements, extending back to as early as 1596.

12. National Library of Ireland

The National Library of Ireland hosts a free, digitized collection of Roman Catholic parish registers dating from the 1740s to the 1880s. They are not indexed, so you will need to know as much detail as possible about your ancestor’s baptism or marriage- or use indexed information from other sources as a guide.


Lastly, for those with ancestors hailing from Northern Ireland counties, be sure to check out the General Register Office of Northern Ireland (GRONI) – and the Public Record Office of Northern Ireland (PRONI). GRONI offers a online database of civil registration records, including births, marriages and deaths from 1864.
