Updated on August 11, 2020, this PDF document (1.9 Mb/628 pages) lists over 26'970 different surnames, allied to our family by mariage, directly or through sibling, cousins... all linked, in Switzerland and abroad.
The list includes usage as well as earliest and latest dates present in my genealogy.
Apart from the "X", all letters of the alphabet are represented !
Note that for many of these surnames I have little information when its representation (usage) is low in my database. For those most represented, see this page .
