Desendants of Aksel Aag, Minnesota

Hi Im searching for any information regarding Aksel Aag born 1885 and his two younger brothers Alfred born 188? and Johan Aag born 189?. They emigrated from Meløy in Norway right after 1900, Im not sure exactly when, but I was told Johan died in the USA in 1908 so it had to be before that. Alfred returened to Norway after a while, but Aksel married Sadie Olivia in 191? and I think they setteled down in Minnesota. I have found information regarding Aksel and Sadie deaths in a register listed on My Genealogy pages, and when I was searching Ellis Island files I found that Aksel, Sadie and two of their children were passengers aboard 'Bergensfjord' in 1920. I think this is a register of a visit to Norway, so I wonder when Aksel and his brothers first arrived. I've been told Alfred worked in a mine during world war one, but I dont know if that information is correct, and where do I look for that information ? There has to be decendants of Aksel and Sadie still living in the USA, and I would appriciate any information that leads me to solve this puzzle. Greetings from Norway Hege Edited by - hegeaagfjeld
