Morken family

I hope someone can be able to help me find my great-grandfather. He was born in Soendre-Fron in Gudbrandsdalen in Norway 24'th of July 1894 ca. His name was Kristian Morken. He arrived Ellis Island, New York, march-april 1916 in Bergensfjord from Oslo (Kristiania)In the shipsmanifest he said he was going to Alberto, Minnesota, but I can't find him anywhere. He might change his name. He also had a sister who came to America. Her name was Hannah Morken. Kristian left his seven brothers back in Norway. Their name was: Anton, Mathias, Olaf, Ole, Thorvald, Karl and Johannes. I hope this name look familiar to anyone who can tell me what happened with Kristian Morken. Thanks in advance. Bente-A.
