C.B. Olsen

My father has a painting that has been in our family for generations. The painting is of a bark ship named “Collector”. The shipmaster was named C.B. Olsen, who we believe is somehow related to us. The wording on the bottom of the painting says “Collector of Arendal Capt. C.B. Olsen”. In my research I was able to determine that the ship left Arendal on May 14, 1879 and was sunk by the North German Lloyd steam ship “Oder” on June 8, 1879. In the accident an unnamed steward, Nils Winter, Edward Eliassen, Francks Kgllere and Paulus Nilsen were lost, all natives or Norway. The survivors were C.B. Olsen (shipmaster), M. Marcuson, Julius Olsen, Engel Lasson, Anton Anderson, Evald Olsen, John Johnson and a boy named Andras Christensen survived. The Collector was owned by “O.P.O. Olsen & Co.” of Arendal, Norway, was built in 1865 and registered 456 tons. I am trying to trace my family back to this ship and to C.B. Olsen. I am having a difficult time not knowing what “C. B.” stands for. If anyone can provide and assistance or has any knowledge on this ship or C.B. Olsen, I would greatly appreciate it.
