The Fergus Falls, MN, Kielmeyer/Christopherson Home Page

The surnames which I am researching are "Kielmeyer" and "Christopherson". The Kielmeyer family is from the Fergus Falls, Minnesota, area, and the Christopherson family is from Fingal, North Dakota. My parents' names are Ormon Louis Kielmeyer and Kathryn Viola Christopherson. I have information five generations on both sides of my family but am missing dates and places of death. Any information provided to me would be appreciated.
I am willing to share the information I have collected.
