George Edward Archibald Augustus FitzGeorge Hamilton (30 December 1898 – 18 May 1918) was a British Army officer during World War I and a distant relative of the British royal family.
He was the only son of Sir Archibald Hamilton, 5th Baronet and Olga FitzGeorge, and was the heir to the Hamilton baronetcies of Trebinshun House and Marlborough House.
FitzGeorge Hamilton's godparents were his great-grandfather, Prince George, Duke of Cambridge, and the Duke and Duchess of York (later titled as George V and Queen Mary).
His parents divorced in 1902, and during his adolescence he attended Hawtreys, Winchester College, and the Royal Military College, Sandhurst.
In 1917, FitzGeorge Hamilton was commissioned as a Second Lieutenant in the Grenadier Guards, the regiment in which his great-grandfather, the Duke of Cambridge, also served.
He served in World War I and was killed during an aerial bombing raid in Warlincourt-lès-Pas, France, in 1918.
Following his father's death in 1939, the Hamilton baronetcies of Trebinshun House and Marlborough House passed to FitzGeorge Hamilton's uncle Sir Thomas Sydney Perceval Hamilton.
