I am not sure if this makes sense, but I have the book "Windsor Township - Heritage & Horizons" by Thelma Caruss.I checked it and the closest I could find in the Pioneer Family Directory is the surname TIEDGEN.
I did a little further checking on line, and the ones who could be the right ages to be siblings to your Christina would be Asmus and Dietrick.

If these could be your people, you should find other things on line, but due to transcription errors, you'll need to find clever ways to search.
This is not my family, but I would be interested in knowing if you have any luck.
