Gunnar, Paul and John Dragsjø, seeking information

On behalf of a good friend who is looking for information on relatives which with a modern language went to America on a shortstay work visa to earn money to invest at home. My friend is looking for information about their whereabouts and specially where and for whom they worked. 1 Gunnar Einarsen Hugaas, born 14.04.1871 in Selbu municipality, Norway. No informatioan on his departure, arrival or stay other than he worked as a farmhand probably in Minnesota, Illinios or adjacent states. 2 Paul Einarsen Dragsjø, born 1869 in Selbu municipality, Norway. His family name could have been Dragsjøen and Dragstsjø but in all cases most likely anglicised to Dragsjo, Dragstsjoen or Dragsjoen. Immigration wrote his name as Draxjø at the card at departure. Paul told immigration in Norway that his destination was Minneapolis, Minnesota and left on June 12, 1907 3 John Einarsen Dragsjø, born 05.02.1879 in Selbu municipality, Norway. For his family name goes the same as for Paul. John told to the immigration that his destination was Grove city, Minnesota and left Norway on April 7, 1903
