This is the website of Jochen Karl Mehldau, the foremost authority on Wittgenstein church books and other records.
If you are looking for your ancestors from the Wittgenstein area, you have come to the right place.
The Wittgenstein Family Database contains the family relationships for more than 150,000 individuals. Most of them lived in the former Kreis (county of) Wittgenstein (North Rhine-Westphalia, Germany). The database also contains ancestors or descendants of some individuals who have lived outside of the area.
All individuals that were registered in the Wittgenstein church records before 1875 are also registered in the Family Database. The data has been compiled, entered and vetted. The data was supplemented with information from other sources.
Specific information and records from the database are available for a small fee.
