I know some things about David he was my great great grandfather. He was the Captain of the Bark Ohio out of New Bedford. His last journey he was accompanied on his voyage by his wife Mary and son Billy. I am the grand daughter of Margaret Fenton Headland who was the daughter of Frederick Reed Fenton and Lillian Baker Fenton of Detroit and Lakeside Michigan later of Chicago and Los Ange!es. Margaret was one of 4 children. Frederick Reed Fenton Jr. , Margaret Fenton Headland, Dorothy Fenton, Helen Fenton Lambert. Reed was an investment Banker like his father.
