Jens Bertelsen and Joanne Otto

I am looking for more information on the following people: Jens (spelled Yens on his daughter's US death dertificate) Bertelsen and Joanne Otto. Their daughter Inga Bertelsen was born on 4/19/1876 in Norway. On her emmigration papers in 1894, she listed her last residence as Greaker Norway. Another daughter Jensine Bertelsen was born about April 07, 1883 in Norway. Her emmigration papers in 1897 says her last residence was Tune, Norway. I know that the sisters had at least 1 other sister who stayed in Norway, and that they left Norway to escape a "mean" stepmom. So Joanne must have died before 1894. I did find this listing in the 1900 census from Tune that could possibly be Jens Bertelsen Hushald nr.
