Great Grandmother

Hello My great grandmother was Laura Augusta Foldoe she was born Aug 12 1876 in Jorgensmoen, Tynset Norway. She married William Alton Fenton on January 20, 1900 un Ulen Mn. I would like to find out her family in Norway but can't seem to find out when she emigrated from Norway. I believe Embretsdatter was also a name ie Laura Augusta Embretsdatter Foldoe Fenton. Would appreciate any little thing that you can do to help me. Thanks Christy
