While my car was in for service, I walked down to the Maritime Museum. Read a thesis on whaling written in 1989 with lots of sources and an index of people. My great great grandfather was in the list. So I read about him and wrote down sources to find at the state archives. Had lunch while walking to the archives (uphill) then four hours checking microfilms. Found a log book written about a whaling voyage where my relative was commander of the ship. Allowed to take digital copy of all 80 pages of the log. Will read once I get more time.
