Wilson Line (Christiania - Hull)

Has anyone information on sailings with Wilson Line between Chritiania, Norway and Hull, England. I am looking for information on routes, sailing times, crew, captains etc. My great-great grandfather was Captain George Pepper, and he was Captain on one (or more) of these ships, and received 'St. Olavs orden' for his service. Any good links or searches on the net? All replies are much appreciated. Thanks:) Jules
