It was named for Captain Jeremiah O`Brien USN and his five brothers: Gideon, John, William, Dennis and Joseph. The O`Briens were crew members on board the sloop Unity, which captured HMS Margaretta at the entrance to Machias harbor on 12 June 1775. O’Brien was decommissioned on 24 September 2004, and was later sunk as part of a training exercise in 2006.
