Gustave Adolf GABRIELSEN, mariner

I am seeking info on Gustave Adolf GABRIELSEN who, according to family stories, was a sea captain. He married Gurine Mathilde OLESDATTER in 1871 in Kristiansand, Vest-Agder. They had 4 children. In 1886, Gurine and the children left their home in Oddernes and emigrated to Halifax, Nova Scotia via Liverpool, England. They eventually settled in Harvard, Massachusetts. Supposedly, Gustave was already in Canada by the time they emigrated. I have been unable to find any record of Gustave leaving Norway. Any information on Gustave would be greatly appreciated. S.P.
