Looking for Bergen/Olstad family in Alberta?

I was doing some research on my family when I came across a Nels (Rev. N.J.L) Bergen from Sweden and Emma Magda (Olstad) Bergen from Minnesota they met and married in Alberta Canada and there life was quite an interesting one, information taking up a couple of pages in one of the local history books. From what I read his family was from Sweden and he went to USA then off to Canada after a while. She was from Minnesota USA (parents are presummed from Norway) then went to Alberta Canada. I was just curious if this might help anyone out. you can contact me if there are any ? Khristiane
