Your welcome. The closest one I find is a Bertha Pederson who married a Hans Christianson on 31 Aug 1870. I only have an index so I don't know if this is the couple you are looking for.
It wasn't required that they file the records until 1907 so you might want to check with Grace Lutheran Church as they might have it in their books! Church records can be gold mines. Go back to the link I told you about for the cemetery reading and click on the History link and there is an email address for David Christianson. He is a nice fellow and recently retired. He might be willing to look thru the records for you.
Another thing to keep in mind is that it was not uncommon, even today, for the Winchester area residents to tend to their business in Waupaca or Outagamie Counties Sometimes being on the edges of the county line it was shorter to conduct business in the neighboring county.
The farm name you were trying to look up doesn't do much good here in the states. It usually refers to the name of the farm where they came from across the ocean. When you research there it might come in handy. So, don't discard it yet.
