This is the right Soren. Soren Anderson married Amanda Juliana Holm. Floren, Marion, Beula, and Harley are the children I have.
The socical security death index for Soren is correct, but I am uncertain about Marion. I think Marion Cornell Anderson (b. 6 Feb 1917 and d. 29 Apr 1943) may be the corrct one. He lived in Minehaha County, Minnnesota. The one I found married Else Chrisine Steffensen.
