Looking for Info on the Olsen Nilssen Pederson Families from Bergen Norway

My grandmother Eleanor Inga OLSEN was born on March 01,1910 in Bergen, Hordaland Norway. Story is she came on a ship at 9 years old with family friends (TOTLAND) and Migrated to Provo, Utah.We heard that she was later adopted by an aunt Martha NILESEN from N. Provo.Utah. I am researching anything on my Norwegian family and ANY INFO ABOUT MY GRANDMA ELEANOR. Also looking for info on her brother Harry Adolf OLSEN who has been missing since WW2. He was a merchant marine Born 09/18/1912. Thank you
