To genealogists and historians the Register of Swiss Surnames has become an essential standard reference. Representing the status quo of the year 1962, it offers a comprehensive alphabetical listing of all the families holding citizenship in a Swiss community. Each entry contains information on the place of origin (i.e. community of citizenship), time of naturalisation as well as previous place or country of origin. This site offers free access to some 48'500 entries, as compiled in the third edition of the "Familiennamenbuch der Schweiz" (Schulthess Polygraphischer Verlag, Zurich 1989).
In 1990, the foundation Historical Dictionary of Switzerland (HDS) could purchase the electronic register from the so-called study group "Register of Swiss Surnames". In 2009, it was made accessible over the internet.
