Olsen/Bakken Family of Romedal

I am seeking any information about the family of my g-g. grandmother, Anna Bakken Olsen, who is said to have been born in Romedal on March 7, 1877, to Ole Olsen and Oline Lokting. Her siblings are to include Ingeborg (md. Ludwig Nilsen), Ole, Bertha, Christ (b. abt 1886), Kersti, Ella (b. abt 1887), Nina and Marius. I know very little about this family, and would like to know where they lived, and when and where they were born, etc... Anything would be much appreciated. Anna emigrated to the United States sometime between 1903 and 1908, but I have been unable to find a passenger listing, and settled in North Dakota where she settled and raised a family. She was responsible for bringing her brother Christ and Sister Ella to America as well. Again, any help or advice would be much appreciated. Thanks!
