I have found funeral cards for these two people and wonder if someone might be searching for this family. The first is for;
Conrad Doll, b: 14 February 1861, d: 09 April 1957
The funeral home is Buehler Funeral Home. There is no other information given. The second is;
John Doll b: 09 March 1894, d: 25 April 1974. Arrangements by Hoenig Funeral Home, Mandan, North Dakota.

I hope this information will help someone in their search.
