I agree. I searched the Minnesota State Census (at Minnesota Historical Society/Family History/State Census) for Klara/Clara and Larson/Larsen or Palsmoen/Paalsmoen and did not find her. I did find a Clara Larson age 21 in 1905 in Otter Tail County. Of course, if she did not answer the census, and someone else gave her answers for her, they could estimate her age to be older. Also I suppose she could be married by the time of the 1905 census, but I did not find a marriage for her in the Minnesota Marriage Index.
The Otter Tail County Historical Society has volunteers who will do local look ups. Perhaps a volunteer could visit Our Saviors Lutheran Church in Dalton, Otter Tail, Minnesota to see if there is a marriage record for Clara.
