I wonder if the Brost family I am searching for, is the same?
Casper Peter Brost (1900-1953) married a woman who was born in Norway; Esther Laura Thomseth (1894 - 1977).
Children might be: Donald Curtis Brost (1922 - 1992) and Robert T. Brost (born about 1920). They lived in Hennepin.
(All this is found on the Internet, I have never had any contact.)
