1852 ships/lists help from Christiana, Norway

Hi, Searching for Even Gulbrandsen/Gulbrandson / Hovern, wife Anne Johansdatter w/ their children emigrating to Wisconsin in 1852 from i believe Christiana. They lived on Hovern Farm, Ostre Toten. Would like to know the ship or barks name and picture if any and where they landed here in the U.S.A. One obituary said it took them 9 weeks to cross the ocean. They were carrying a baby girl who was about 6 months old. Her name was Maria Evensen Hovern who was my Great Grandmother. She had another sister and 2 brothers, John and Even Evenson or Everson. Any help out there, i'll be greatly appreciated. Thanks so much. [:)] Rachael (Nelson) Gehringer [email hidden]
