    Marshall ship captain  - Ramsgate
    Hi, I am looking for any information about John Marshall born Ramsgate 15 Feb.1748, In 1788 he was the captain of the " Scarborough" a ship of the first fleet taking convicts to Australia. He also saw action during the American war of independance and the Napoleonic wars. He was wounded on the ship "Diana". He died in 1891 aged 71. The Marshall Islands in the Pacific are named after him. I know John moved to Australia after the second fleet disaster but not exactly when. He is my 3x great grand father.John also had a brother that died during the 1788 voyage, but I do not know his christian name. Can anybody help with any more information please.
    
    British merchant sea captain John Marshall's ship, Scarborough, was
    built in the shipyards in Scarborough, Yorkshire so this is most
    likely where it got it's name.  The ship was actually owned by by
    merchants Thomas, George & John Hopper of Scarborough,
    Yorkshire.  Here are a few technical details on the ship:
    
    The Scarborough was built in 1782 in Scarborough, Yorkshire by ship
    builders John Howard and Ben Fowler.  By design, she was a
    two-decked, barque-rigged vessel (3 masts, square rigged on all but
    the aftermost mast) and her dimensions were 111.6 feet long and 30.2
    feet wide, and weighed 411 tons.  Her Deptford survey in 1786 noted
    that the ship now weighed 418 tons and that height between decks was
    6'1" abaft, 6'2" amidships and 5'11" afore.  The vessel was armed and
    capable of carrying a crew of around 35 seaman.
    
    This is the same ship he sailed to Australia (Botany Bay) carrying a
    load of convicts with the First Fleet.  In 1788, Captain Marshall
    left Australia after being released from government service by NSW
    Governor Arthur Phillip (he had fulfilled his duties) and sailed
    north by northeast heading toward Whampoa, China, now under contract
    with the London East India Company.  He, sailing together with
    Captain Thomas Gilbert of the "Charlotte", made his way through the
    south Pacific islands he discovered and charted that later became
    known as the Marshall Islands (Gilbert discovered and charted what
    later become known as the Gilbert Islands).  It's interesting that
    Captain Marshall named one of the islands "Hopper's Island",
    obviously after the surname of the Hopper brothers that owned the
    ship he sailed to make his living.
