Ottenbach

 Notes: It is generally accepted by researchers in Switzerland that the name Ottenbach came from an Allemanic man named "Otto" who lived in the area. The word Bach means a creek; brook; or a rivulet. Since the River Reuss is the distinguishing feature of the community: Otto's Bach, or Ottenbach.

The name Sidler was spelled Siedler but in modern times is spelled Sidler. Billeter wisely standardized the spelling of Sidler. This is important for ease of computer searching. There are many spellings of Jacob as well but Jakob or Jacob have become the standard. The earliest Sidler in Ottenbach who Julius Billeter found goes back to Johannes Sidler born 1568. They and had 10 children!
