Midshipman Graham Francis James Trounson (1897-1914) was the only child of Francis Thomas Trounson and his wife Kate, daughter of Thomas Martin. Through his mother, he was a descendant of George Graham, who was associated with the beginnings of the Naval Observatory. He was educated at the Whitgift School Croydon and later joined the 'Mersey' training ship for White Star officers. In 1911, he became a cadet in the Royal Naval Reservee.
At the start of the First World War, Trounson was a probationary Royal Naval Reserve midshipman in the armoured cruiser HMS 'Good Hope', flagship of Rear-Admiral Sir Chrisopher Cradock's small British squadron in the eastern Pacific. On 1 November 1914 this was overwhelmed by the more powerful German Pacific squadron of Vice-Admiral Maximilian von Spee at the Battle of Coronel, off the coast of Chile. Both the 'Good Hope' and the armoured cruiser 'Monmouth' were sunk - the former exploding - and there were no survivors from either ship, a combined loss of 1,654 men.
He is also known to have worked on P&O liners.
