Project History
The project was born from genuine curiosity: understanding how surnames are distributed around the world and what they tell us about migrations, culture and the history of peoples. That simple question turned out to be a gateway to a fascinating universe of demographic data, historical patterns and cultural connections.
What started as a small data experiment has grown over the years into one of the most comprehensive and widely consulted surname databases in the world, with millions of annual visitors from every continent.
