I am writing in response to your post regarding the Hammerstrom family. I noticed that you mentioned your relative being from the Minneapolis area and I am throwing out a long shot here, but my great maternal grandmothers maiden name was Hammerstrom and she worked at the Nicolett (sp?) Hotel where she met my great grandfather. There is much confusion over my grandmothers true given name; my mother says that grandmas name was Brikken, and that she changed it to Bertha when she came to America. I have searched and have found nothing about her, nor her husband; Gustaf Erik Jonnson, on any searches I have done yet. The only thing that my mother could tell me was that grandma came from a village named Bollnes (the "o" is supposed to have the little dots over it).
Does any of this sound familiar to you?
I look forward to hearing from you,
