My first question is were they Catholic or what Protestant religion? And are the buried in a Kimball Cemetery or one in the area, there are several in the area?
I will get hold of a person that lives in Kimball to find out who now has cemetery records.
Did they live right in Kimball?
Did you check on find a grave?
I lived in that area many years ago, and married into a family that was there before SD became a state and some of them were Bohemian.
