Ancestry Research in Ireland

Welcome to Irish Genealogy

Records for the Republic of Ireland and Northern Ireland (UK) can be found at the National Archives of Ireland and National Library in Dublin, as well as the Public Record Office of Northern Ireland (PRONI) in Belfast. The Family History Library in Salt Lake City, USA also holds billions of records relating to Irish genealogy. In addition, many records can also be found at the local level at civil registry offices, church parishes, regional archives, and local libraries throughout Ireland. Many helpful databases are also available online, with sites like Ancestry.com, FamilySearch, MyHeritage, Roots Ireland, and Findmypast being some of the best places to visit when beginning your quest into your Irish origins. Our specialized digital archive explicitly bridges the gap between southern gentry lines and northern Ulster-Scots industrial migrations. We systematically map pre-Famine parish logs, historic land deeds, and municipal voter registries into interactive pedigree charts to help you discover how your ancestors navigated these historic corridors.

Irish Ancestry, Genealogy, and Family History

Humans have lived in Ireland for the past 12,500 years, as can be seen by the physical evidence of bones, tools, stone structures, and other artifacts left behind there. The geographic area of Ireland wasn't mentioned much in historical sources until the advent of the Roman Empire. During the early Middle Ages, most of the country converted to Christianity, and by the 12th century Ireland was colonized by the Anglo-Normans. During subsequent centuries Ireland was under the jurisdiction of the United Kingdom of Great Britain and Ireland until the Republic of Ireland gained independence in 1922. At that time, the country was divided between between the United Kingdom, which retained most of the historical area of Ulster, and the Republic of Ireland in the south. Perhaps your ancestors played a part in this fascinating history, and left behind important documentation that connects to your present-day genealogy? To preserve this rich heritage, our network hosts open-access relational databases packed with un-paywalled land deeds, pre-Famine parish transcripts, and cross-border maritime registries. This structured digital archive allows researchers to effortlessly bypass corporate subscription gates and trace their lineage backwards through time. Whether you are seeking direct answers in our open trees or require high-ticket professional retainer options for passport verification, our services are fully optimized to map your family's unique footprint. To help get you started on this exciting voyage of discovery, we’ve assembled an expert team of genealogists to help you uncover the unique story of your family's journey through time.

Getting Started with Your Research

Tracing your family back to Ireland is most successful when you move step-by-step from home records to local Irish geography. Start by gathering family letters, obituaries, marriage certificates, and passenger manifests in your home country to pinpoint an ancestor's approximate birth year, religion, and—most importantly—their county, civil parish, or townland of origin. Because the 1922 Four Courts fire in Dublin destroyed most 19th-century censuses and pre-1864 civil records, identifying your family's exact parish or townland is essential before searching surviving 1901 and 1911 census returns, Griffith's Valuation, Tithe Applotment Books, and local church registers. You can also explore our open-access celebrity and clan trees below to see how surname networks and collateral relatives connect across Ireland and the global diaspora.

Linking your traditional paper trail directly to targeted surname projects and specific haplogroup registries allows you to systematically verify deep-trench ancestral lineages across the transatlantic corridor. Cross-referencing your DNA matches with localized land valuation records and civil registries often reveals the exact townland or parish of origin.
