Looking for Norwegian grandmother

My mother's mother was Anne Olson who emigrated to USA from Norway in the early 1900's. She married Syver Stenseth in North Dakota in 1905. She died in North Dakota in 1918. I would like information regarding her birthplace or residence in Norway, any current relatives, and how she came to USA. My mother and all her siblings are deceased so I have no means of acquiring information from family. Bless you for any help as I will be traveling to Norway this month and hope to visit her home.
