G. Paulsen - on bark Martha 1867

There was a passenger # 46 named G. Paulsen on the bark Martha which sailed from Christiania on April 30, 1867. I think he may be my gr-grandfather Gilbert Paulsen. Is there any more information to be found on the passengers than what we see on the passenger listing which shows that he was from Tønsberg? My gr-grandmother Marie - passenger #137 was also on that voyage with her mother and step-father but not apparently in company with G. Paulsen.
