VON WHAT ?
A natural inquiry.
I have three parts to my last name. Werdmüller (or Wertmüller) is the family surname, von translates to "from", and Elgg is the town in Switzerland my ancestors hail from.
The short version of the story...
A long time ago, three brothers left Switzerland to join the Dutch navy. They were stationed in Indonesia, where they married and procreated. Generations later, their children moved to the USA. The rest is history.
