Dear Ms. Buchan,
Thank you for posting your request on History Hub!
As the previous poster noted the correct ship name, we searched Chronicling America: Historic American Newspapers and located a reference to the Bark Ocean arriving at New York as reported by the Herald steam yachts on June 07, 1872. From this reference it is noted that the ship has a “NG” designation, which may refer to the North German Lloyd Company, Norddeutsche Lloyd. While we were unable to locate specific information on the Bark Ocean, there may be comparable information available by browsing the NDL fleet list.
A “bark” or “barque” was a sailing ship. It was differentiated from a "ship", by its rigging. A bark has 3 masts, with the foremast and mainmast square rigged and the mizzenmast fore-and-aft rigged. Barks were often rerigged as ships and vice-versa.
We hope this is helpful. Best of luck with your family research!
