House: Hanover: Father: George II of Great Britain: Mother: Caroline of Ansbach: Prince George William of Great Britain (13 November 1717 – 17 February 1718) was a member of the British royal family, second son of the Prince and Princess of Wales (later King George II and Queen Caroline).
Prince George was born on 20 December 1902 at York Cottage on the Sandringham Estate in Norfolk, England. His father was the Prince of Wales (later King George V), the only surviving son of King Edward VII and Queen Alexandra. His mother was the Princess of Wales, later Queen Mary, the only daughter and eldest child of the Duke and Duchess of Teck.
Prince George of Cambridge was educated in Hanover and from 1830 in England by the Rev. J. R. Wood, a canon of Worcester Cathedral. Like his father, he embarked upon a military career, initially becoming a colonel in the Hanoverian Army and then, on 3 November 1837, becoming a brevet colonel in the British Army. 
George suffered a final relapse in 1810, and his eldest son, the Prince of Wales, became Prince Regent the following year. When George III died in 1820, the Regent succeeded him as King George IV. Historical analysis of George III's life has gone through a " kaleidoscope of changing views" that have depended heavily on the prejudices of his biographers and the sources available to them.
George's only legitimate child, Charlotte, had died from post-partum complications in 1817, after delivering a stillborn son. George III's second son, Prince Frederick, Duke of York and Albany, had died childless in 1827, so the throne passed to the third son of George III, Prince William, Duke of Clarence, who reigned as William IV.
The future George VI was born at York Cottage, on the Sandringham Estate in Norfolk, during the reign of his great-grandmother Queen Victoria. His father was Prince George, Duke of York (later King George V), the second and only surviving son of the Prince and Princess of Wales (later King Edward VII and Queen Alexandra).
