Who did Elen Olsdatter from Aure marry in 1881?

My great-grandmother was Elen Olsdatter who was born 14 April 1861 at Aure Prestijeld Nord Møre Norway. Her father was Ole Olsen (born 1824) and her mother was Frederikke Engelsdatter (born 1825), Their farm was Hjællenset in the 1865 census, and Hjælanæs in the 1875 census. Elen gave birth to her first child at sea on 22 Sep 1881. Her child was Fredericka Bertina Severson or Sivertsen. I am looking for information on Elen's husband...and information of their immigration to America.
