What is a brick wall in genealogy?

Whether you've just started your family tree or you've been making discoveries for years, you've likely heard the term 'brick wall' discussed in genealogy circles. But what exactly does it mean? 

Picture this: you're deep into your family history research, following a promising lead about an ancestor. Frustratingly, you find the trail goes cold. Perhaps they disappear from the record with no explanation. With no death or migration records to confirm their next chapter, you're left scratching your head. You try searching in different places, perhaps consulting the newspapers, or looking for answers in other members' family trees, but every path hits a dead end. More than just a small hurdle, this is the phenomenon of the brick wall. 

There are a wide array of historical and administrative reasons you may hit a brick wall.  

Gaps in record collections 

Fires, floods, wars, or poor record-keeping can leave entire decades missing. For example, many Irish census records from 1821 to 1891 were lost in the 1922 Public Record Office fire in Dublin. Local parish registers also might have gaps where the pages were damaged or never completed. 

Ancestors' name changes 

Ancestors who altered or anglicised their names can be tricky to track. A Johann Müller arriving from Germany might appear later as John Miller, or a Bridget O’Malley could be recorded as Bessie Malley in later UK records. 

Migration 

A move to another country, county, or even parish can break the paper trail. A farm worker moving from the countryside to a city might seem to vanish from local records until you search the right location, while emigrants to the US or Australia can disappear entirely from UK sources after departure. 

Illegitimacy 

When a child’s father isn’t named, records may be incomplete or misleading. For instance, a baptism entry might only list the mother’s name, leaving you reliant on other sources such as poor law records or bastardy bonds to uncover more detail. 

Clerical errors 

Misspellings, transcription mistakes, or incorrect ages can also throw you off track. 

Sometimes, a brick wall isn’t a lack of records at all - it’s just that you haven’t found the right ones yet, or you’re searching in the wrong place. A missing ancestor might already be in the records, just under a slightly different name, age, or location than you expected. 

When you’ve hit a genealogical dead end, it’s time to step back, review, and adjust your approach.  

• Re-check what you know. Go back to your earliest confirmed record for that person and verify every detail, as even a small error can throw your family history research off track.  
• Try widening your search. Look at siblings, cousins, neighbours or anyone who may have left the paper trail you're hunting for.  
• Experiment with name variations. This is especially important if you're looking at records prior to the name standardisation of the late 19th century. 
• Think geographically. If you can't find what you're looking for in one location, try tracing possible journeys your ancestor could have made. Perhaps they moved to a neighbouring parish, or boarded a ship from one of the UK's most popular ports.  
• Consider the wider history at play. Researching the historical context of the period may offer you valuable clues, as understanding the world your ancestor inhabited will give you a deeper insight into their life.  

Not every brick wall can be resolved immediately. Some require patience until new records are digitised or archives release restricted materials.  

It's a good idea to organise your genealogy research using online tools like Findmypast's Workspaces. With room to save relevant records and add your own notes, it ensures you can jump right back in where you left off when new leads emerge. 

In family history, a brick wall isn’t the end of the story. It’s just the point where the challenge begins - and where your detective skills, persistence, and creativity come into their own. While genealogy brick walls can be frustrating, they can also lead you to unexpected discoveries. Besides, those hard-earned breakthroughs are the most rewarding of all.
