Looking for Elenora Larsen

My great aunt came to America and settled, I believe, in Hope, ND. Her name was Elinor or Elenora Larsen. She may have married into the Hilton family. Her sisters were Lara (Laura) and Helene (Helena) Jacobsen (married name). Helena died and my grandmother, Laura Larsen Brustad, brought her daughter, Mimi Marie Jacobsen, to America in 1917 when she was four years old. I think she had siblings. Elenora's father's name was Lars Larsen and they probably lived in Kristiania. Any help finding any of these folks would be appreciated. Mange Takk! Mary Brustad Keys
