How to trace Irish genealogy

The way you go about tracing your Irish ancestors depends on what you’re looking for.  

To learn more about a particular family member, start by simply searching for their name within Irish family history records online .  

While gaps in Irish genealogy records can complicate your search, they can be overcome, making those hard-earned discoveries even more rewarding. Be sure to gather all the information you can on your relative before you start. Try asking other family members or checking any old photographs you have. 

To find out more about your family as whole, start a family tree using an online tree building tool. You’ll begin building back through the generations by inputting your details and those of your parents, grandparents and any siblings. 

To maximise your chance of success with your Irish family history, you should gather all the information you can on the relatives you know. Do you have a family member who may be able to tell you more about the older generations? 

Asking the important questions now – like when and where your grandmother was born, or whether your great-grandfather was in the military – may make all the difference further down the line. 

For yourself, your parents and your grandparents , you’ll need the following information: 

• Full name  
• Birth date (and death date where applicable) 
• Place of birth 

The more specific you can get with the location, the better – though even knowing the county or the province is useful to your genealogy research. 

Tracing your Irish family history can be trickier than tracing English, Welsh and Scottish ancestry, for a number of reasons:  

• Most of Ireland’s 19th-century census records were destroyed in a fire at the Public Records Office in Dublin in 1922. Only fragments survive, meaning we can’t trace Victorian Irish ancestors decade-by-decade like we can in the UK or the US. 
• Irish birth, marriage and death records start later than English ones . These historical records are important for building your family tree, as they establish the key milestones in your relatives’ lives. Births and marriages weren’t recorded by the Irish government until 1864, so you have to rely on church records pre-1864. 
• Irish placenames have also changed over time , which can make it trickier to locate your ancestors in the parish, townland or civil registration district that they lived. 

• Start with parish registers – Before 1864, births, marriages and deaths were recorded by churches rather than the government. Baptism and marriage records, especially Catholic parish registers, are often the key to unlocking earlier generations.
• Be flexible with names – Irish surnames and given names can appear in many variations. O’Connor might appear as Connor, Conner or even Conor, while Bridget could be recorded as Brigid. Try alternative spellings when searching.
• Track townlands and parishes – Knowing the exact locality is vital. A single county could contain multiple parishes with similar names, so note down every place reference you find.
• Use newspapers for colour and context – Irish newspapers are rich in detail, reporting everything from farming accidents to local events. Even a small mention of your ancestor can add depth to their story.

Irish family history made easy

Where birth, marriage or death records or censuses aren’t available, you may be able to find the information you need in old newspapers , prison records , workhouse registers and other religious documents – all digitised and easy to search online. 

By using all the family history records available to you, you can build a vivid picture of your Irish ancestors’ lives and delve deeper into the world they inhabited.
