I think these children are the kids of George Hanson and Anna Margret Hansen's daughter Marie, b. 1880.

Her death:
KNUDSON, MARIE MATHILDA

Place of Birth: MN
Mother Maiden Name: RASMUSSEN

The mother's maiden name of Rasmussen makes more sense for a Danish maiden name that Robertson.
Here is Marie/Mary Hansen Knudsen's marriage:
DOUGLAS F - 349
