Robin I saw your letter. I am not related to the Bergstroms or anything but I do not that there were and are Bergstrom's that live in Neenah. They owned Bergstrom Paper there. I also know that the owner had a place in upper Wisconsin near Mercer if I remember correctly which is really not that far from Florence county. I know the place was like on an island on some lake if I remember correctly from what mother told me she had been there a few times. Now for the question I do know that they had the mines up in that area and that could have what brought them to that area also. There were iron mines in the area up there but I dont know when they opened. I had at one time but its been years since I have been up there. Sorry I couldnt help any further. Lynn
