Today, Bührers can be found in various cantons of Switzerland, however, most Bührers still hail from the Canton of Schaffhausen. How did this come about? A time series shows in 50-year steps from 1500 to 2000 (birth dates) where in Switzerland Bührers have been and how they’ve moved.
The earliest recorded Bührer in the dataset is Adam Bührer, who was born around 1533 in Bibern. Long-range migration in earnest starts only in the first of the 19th century.
Note that places have been aggregated at 2018 municipality level (e.g. Bibern and Hofen merged in 2009 with Thayngen). The circle size denotes the number of Bührers.
