There are also death index records for Polk Co for Betsy, Brown, and Gena Marie - all surname Fadness. I couldn't find anything under Fadnes.
With a mother with a surname of Styve, are either Helge or Adolph related to the family you're looking for? Helge should be a male name - Helga is female. Difference in the last letter determines whether the name is male or female.
