1856 emigrans from Norway to USA

Ole Gulbrandsen pa Karihus signed out in the Nordre Aurdal Prestgjeld register that he was emigrating on Mar 22, 1856. I have been unable to find any database concerning emigrees in that year. Is there any archival data concerning that year on record in Norway? I woul dappreciate any clues as to where I might search. Thank you, Inez
