Passenger lists 1849

I found the record of a relative on a church register for emigrants from Gausdal Parish on 14 May 1849. I cannot find any of the family names on your passenger list for 1849. They most likely left from the port of Christiania. Is there a possibility that there was any other ships that left Chiristiania for America in 1849? Their names: Erland Gundersen Bakkum (28) Kari Olesdatter (29) Christian Erlandsen (2) David Johnson Olympia Washington USA
