Ireland and Northern Ireland Research Resources

This list focuses on specialized primary archives, regional databases, and unique research tools for the island of Ireland, excluding the “Big Four” platforms.

Note for 2026: As of this year, the 1926 Census of Ireland is now fully released and freely available through the National Archives of Ireland, providing the first major genealogical window into the post-Independence era.

1. Official National Archives & Civil Records

These are the most critical repositories for primary evidence.

  • IrishGenealogy.ie: The Irish government’s official portal. It provides free access to images of civil birth (1864–1925), marriage (1845–1950), and death (1871–1975) records, as well as several Dublin-area church registers.
  • National Archives of Ireland (NAI): Features the 1901, 1911, and now 1926 Census records. It also hosts the Tithe Applotment Books (1823–1837), Soldier’s Wills, and the Valuation Office books (Field, House, and Tenure books).
  • Public Record Office of Northern Ireland (PRONI): The primary archive for Northern Ireland (Antrim, Armagh, Down, Fermanagh, Londonderry, and Tyrone). Essential for Will Calendars, the Valuation Revision Books, and unique landed estate papers.
  • GRONI (General Register Office Northern Ireland): The official site for Northern Irish civil registrations. Unlike the Republic’s free site, this uses a credit-based system to view records.
  • Virtual Record Treasury of Ireland: A “digital reconstruction” of the archives lost in the 1922 Four Courts fire. It aggregates surrogate records (copies found elsewhere) to replace lost 18th and 19th-century data.

2. Church & Religious Records


3. Land, Tax, and Property Records

  • AskAboutIreland (Griffith’s Valuation): The most important 19th-century land record. It is free and includes maps linking your ancestor to a specific plot of land.
  • Registry of Deeds Index Project: A massive volunteer effort to index memorials from the Registry of Deeds (1708 onwards). Essential for middle-class, merchant, and landed families.
  • Landed Estates Database: Provides information on the landed estates and gentry houses in Connacht and Munster (c. 1700–1914).

4. Regional & Volunteer Projects

  • RootsIreland: Managed by the Irish Family History Foundation. While it is a paid subscription, it is independent of the big platforms and holds the most extensive collection of transcribed (not just imaged) church records.
  • IGP Archives (Ireland Genealogy Projects): A free, volunteer-run repository containing headstone photos, transcriptions, and local notices organized by county.
  • Ulster Historical Foundation: Specializes in the nine counties of Ulster. Excellent for specialized Northern Irish research and the “Guild of One-Name Studies.”

5. Military, Police, and Occupations

  • Military Archives (Ireland): Contains the Military Service Pensions Collection (1916–1923) and the 1922 Army Census, which are vital for tracing ancestors involved in the Irish Revolution.
  • Royal Irish Constabulary (RIC) Records: (Often found via the UK National Archives). Useful for tracing ancestors who served in the pre-1922 national police force.

6. Mapping & Placename Tools

Irish research often fails because of “townland” confusion. These sites solve that:

  • Logainm.ie: The official placenames database of Ireland.
  • Townlands.ie: A community-mapped database of all 60,000+ Irish townlands with modern GPS boundaries.
  • John Grenham’s Irish Ancestors: The gold standard for seeing where surnames were historically concentrated and identifying which specific records exist for a given civil parish.

7. Newspapers

  • Irish Newspaper Archives: The world’s largest online database of Irish newspapers. It is separate from the British Newspaper Archive and includes many small, local Irish titles that are otherwise unavailable.
