Geogen v4


About Them:

Thank you for providing more information! Geogen v4 is a free online tool that maps surnames on a modern German map. It was created by Christoph Stöpel and is designed to help people explore the distribution and concentration of surnames across Germany.

Geogen v4 uses data from telephone books, which means it relies on relatively modern data. However, it also includes historical data from the 19th and early 20th centuries, which can be helpful in understanding the distribution of surnames over time.

To use Geogen v4, you can enter your surname in the upper input field and click the “Research” button. It’s important to note that German special characters (ä, ö, ü, and ß) are distinct letters, so you will need to look for variations of your surname with and without these special characters. For example, you should search for both “Mueller” and “Müller” to get the most accurate results.

Once you’ve entered your surname and clicked the “Research” button, Geogen v4 will generate a map of Germany showing the distribution of your surname. The darker the shading in a particular region, the more common your surname is in that area. You can also hover over specific regions to see the exact number of people with your surname living there.

Overall, Geogen v4 is a helpful tool for anyone interested in exploring the distribution of surnames in Germany.
