I think you should take another look at the passenger list for Klara arriving in New York. It looks to me like you might have picked up the wrong line for where Clara "Paalmaen" (as ancestry transcribed it) was heading. The way I read it is:
Line 7 Paalmoen, Clara Gunhilde, 15, female, maid, ", ", ", Scandanavian, ", Fort Dodge, Iowa, Self, Kr 36, no, Sister Clara Johansen, 14 Pine St. Fort Dodge, Iowa, "
I believe the Uncle Hans Bardalen is actually for the next passenger, Ida Nordby.
So that might give you another direction to search.
