There was a Christian Kindschi, I think he was C. I. (Ivan)Kindschi. who was part of the Kindschi clan that originally came to Wisconsin and settled in the Praire Du Sac area in approximatly 1850. I kno that some of that family, in later generations, moved to the Dakotas and so it is not out of the question that Montana would have been a destination also.
There are a number of Kindschis still farming in Sauk county Wisc.
Sorry I cant provide more information.
