The family portrait attached has a photographer stamp of Clark, SD. It is possible this family resided in Clark, Kingsbury, Brookings or even Lake county of South Dakota.
It is assumed that this is a father, mother, 7 daughters and 2 sons. The father resembles Bertinuis Severson, but the family make-up does not match his descendants. I am hoping someone has seen this photo or similar ones and can identify this family. It is highly possible they are related to the following lineages -- Bjordahl, Bjornesen, Sjursen or Severson.
