Olaus Nielsen & Even (Evind) Gulbrandsen

Hello, How may I find a passenger list that left Christiana, Norway in 1865 to an unknown Canada port or an U.S. port? I'm sorry but I do not have any information what ship my Great Grandfather left on. He ended up in Wisconsin. I have searched the link provided in Canada above with no luck. Would there be a place where I can write for an existing find? I will even be glorfied if I knew the name of the ship and where it landed. His name: Olaus Nielsen, Born-1842, Vestre Toten, No. Another request if so possible, a ship that left from Norway in 1852 to Canada or U.S.A. Leaving possible from Christiana. Even (Evind) Gulbrandsen from Hurdal Anne (wife) Andersen from Hurdal 5 children last names Evensen One was my Great Grandmother: Marie Evensen Hovern, she was a few months old at the time. Thank you Very Much for any help you can provide. Rachael
