In England, the future King George the Fifth is born at Marlborough House in London.

Born in Marlborough House in London at one o'clock in the morning, George Frederick Ernest Albert was the second son of the Prince of Wales and his Danish-born consort, Princess Alexandra.  Third in line for the throne after his father and elder brother, he joined the Royal Navy at an early age.  His brother's 1893 death moved him up the line of succession and when his father died in 1910, he became King George V and reigned until his own death in 1936. He was grandson to Queen Victoria and grandfather to Queen Elizabeth II. (By John Osborne)
