Trying to find info on Johannesen and Larsen famil

Hi! My great--grandparents came to the US in 1901 aboard the SS Norge from Christiania, Norway. I have copies of their Application for A Certificate of Arrival & Preliminary Form for Petition for Naturalization. These papers are my source of information. My great-grandfather;s name was Christian Johannesen born on 4/6/1880 in Sheberg, Norway. His mother's name was Olina Johannesen. No father's name listed. His last residence in Norway was Sarpsborg. He married Josephine Marie Larsen on 6/20/1900 in Fredrikshald. She was born in Fredrikshald, Norway on 2/13/1874. Her father's name was Johannes Larsen and her mother's name was Johanna Sophie Jakopren(maiden name). I know she had a brother by the name of Anton Larsen who came to the US before they did. They lived with him in Chicago, Illinois after they got to the US and he purchased their tickets for them to come to the US. She also had a brother by the name of Johan who traveled with them to the US. Marie would have been pregnant with their first child, Sofia, when they left Norway. Sofia was born on 12/2/1901 in Chicago, Illinois. They entered the US at Ellis Island, New York on 6/7/1901. My great-grandfather did become a US citizen on 4/18/1941but my great-grandmother had passed away in 1940 before she became a US citizen. Any information about these two families would be greatly appreciated. I never got to meet them and there are no pictures of them that I know of. All I have are the copies of those papers. Thank You!
