Tracing Roots

Tracing Irish ancestry can be both rewarding and challenging. Ireland has a rich history, but many records were lost in the 1922 fire at the Public Record Office in Dublin. Despite this, there are still millions of surviving records that can help you uncover your Irish family story. With the right approach, you can make real progress in discovering your Irish roots.

Civil Registration (1864 onwards)

Civil registration of births, marriages, and deaths began in 1864 (non-Catholic marriages from 1845). Certificates provide names, dates, parents, and addresses.

Access: Free indexes and images are available at IrishGenealogy.ie.

Census Records (1901 & 1911)

These two census years are the only complete surviving sets, but they’re a goldmine. They include:

• Full household listings
• Names, ages, occupations, literacy, and language spoken
• Free and fully searchable online

Access: National Archives of Ireland Census.

Parish Registers (Pre-1864)

Before civil registration, parish registers are essential for baptisms, marriages, and burials. Catholic and Church of Ireland records survive in varying degrees.
Access:

• Catholic parish registers (many digitised) via the National Library of Ireland.
• Protestant records often held by the Representative Church Body Library or local archives.

Land and Property Records

In the absence of many census returns, land records help bridge the gaps.

• Griffith’s Valuation (1847–1864) – lists occupiers of land and property.
• Tithe Applotment Books (1820s–1830s) – record landholders and payments.

Access: Both sets are digitised and available free via the National Archives of Ireland.

Probate and Wills

Although many probate records were destroyed in 1922, surviving collections can still be found:

• Calendars of Wills and Administrations (1858 onwards)
• Some diocesan copies and abstracts

Access: Available at the National Archives and regional repositories.

Military and Emigration Records

Millions of Irish men and women emigrated or served abroad.

• Passenger lists for ships to the US, Canada, Australia, and Britain
• Military records for Irish regiments in the British Army
• Emigrant letters and newspapers in local archives

Access: Available on Ancestry, Findmypast, and some national archives.

Tips for Success in Irish Research

• Always identify the county and parish — Ireland’s records are highly localised.

• Combine free national sources with subscription databases for the best results.
