Thanks for trying. I am the Great Granddaughter of Otis Severson. His only child to have offspring was my grandmother Frances (Severson) Paulson and her only child is my dad Loel Paulson.
I received the copy of this picture from Idor Severson; he is my grandmother's double cousin. Idor's parents were Ben & Clara (Bjordal) Severson and my grandmother's parents were Otis & Lena (Bjordal) Severson.
It is possible that the family in the picture is a relation down the Bjordal line, possibly Bert Severson's brother's family, or maybe just family friends. The mystery will continue...
