It’s easy to take surnames for granted, as they’re just part of who we are. The thing is, surnames haven’t always existed, and they were invented more recently than you might think. Once upon a time, people were known by a single name because that was more than enough for those living in small communities. Everyone knew who John or Alice was, but as populations grew and towns and cities formed, the need for surnames arose. Surnames helped to differentiate people sharing the same first name, and, just like that, John the blacksmith became John Smith, Alice who lived near the hill became Alice Hill, and so on. These names stuck, and they were then passed down from generation to generation. The earliest documented surname is widely believed to be “O Cleirigh” (modern: O’Clery), which can be found in Irish annals dating back to 916 AD. The O’Clery family were hereditary historians and poets, which represented high-status roles in medieval Irish society. So, what else can we derive from someone’s surname? Well, it can hint at what your ancestors did for a living, where they came from, or even the kind of personality they had. For example, a name like Chapman suggests they were a trader, whereas Greenwood might point to them living near a forest. Surnames are more than just labels. If your name is on the unusual side, the chances are better that you’ve got kin around the world. The rarer the surname, the more likely it is that there's only one biological family accounting for it — only one founding ancestor.
