Anne Erlandsdotter Lien

I am looking for information about my gggrandmother, Anne Erlandsdotter Lien, born in Vågå, Norway in 1841 or 1842. She left Norway as a widow in 1888/1889, and brought with her her children, Erland, Østen, Anne and Mari (my greatgrandmother). They went to Lake Hanska, Minnesota, where Anne's brother, Erland Erlandsen Lien lived. He lived at a farm called the Rolandsfarm, together with his wife (Anne Hansdotter), and their children. He had a daughter called Anne that married a man called Olaf Solberg, we don't know if his other children had any family. My ggrandmother, Mari, met her husband in America, and they moved back to Norway. She was the only one of Anne E. Lien's children that got children, the other ones were unmarried. Does anyone know anything about these people? [?]
