I'm researching the following family names.
Camenzind, Kreutzer, and Lagger. These folks came from Valais, Switzerland to America from the 1890s - 1903. Many came out to California (San Francisco and Sacramento) and also Oregon and Washington States. I have information on them arriving in America and records in America but am trying to push back to the Swiss records. Does anyone know where/how to obtain Swiss records?

Thanks for any assistance.
