I assume from your user name that you are a male Widmer whose line emigrated from Switzerland about 1850. Very cool. My line was exiled from Switzerland in 1671, and eventually came to the US in 1717.
Have you considered getting your DNA tested for genealogical purposes? I'd love to know if our families might be related.
I have had mine done with familytreedna.com, where we have a "whitmore" project. This is intended to cover whitmer/whitmore/wetmore/widmer/witmer etc.
Keep in touch in any case!
