This is a long shot, but here goes...
In my own genealogical search I found our family farm was sold to Roy Dillman. My interest initially was finding a picture of the farm. However, I can offer:
In 1921:
"The Roseth family lived for many years on the old home place four miles northeast of town, now occupied by Roy Dillman family."
Thinking they/we may be related... I did some research...
Roy W. Dillman was born 1885 in MN, married Addie M Coyle (born 1882) on 29 Apr 1908 — Preston, Fillmore Cty, MN
Children: Orville C, Wendell C, Everett L and Viola G.
1930 census has them in: Claremont, Dodge Cty, MN
