Early life. Frederick was the son of Crown Prince Frederick William of Prussia and his wife, Sophia Dorothea of Hanover. He was born sometime between 11 and 12 p.m. on 24 January 1712 in the Berlin Palace and was baptised with the single name Friedrich by Benjamin Ursinus von Bär on 31 January.
On his return to Great Britain, the Duke took his seat in the House of Lords, where, on 15 December 1788 during the Regency crisis, he opposed William Pitt's Regency Bill in a speech which was supposed to have been influenced by the Prince of Wales.
Prince Alfred of Great Britain (22 September 1780 – 20 August 1782) was the fourteenth child and ninth and youngest son of George III and his queen consort, Charlotte of Mecklenburg-Strelitz. In 1782, Alfred became unwell after his inoculation against the smallpox virus.
Frederick and Victoria were great admirers of Prince Albert, Queen Victoria's husband. They planned to rule as co-monarchs, like Albert and Queen Victoria, and to reform what they saw as flaws in the executive branch that Bismarck had created for himself.
George mainly lived in Great Britain after 1714, though he visited his home in Hanover in 1716, 1719, 1720, 1723 and 1725. In total, George spent about one fifth of his reign as king in Germany.  A clause in the Act of Settlement that forbade the British monarch from leaving the country without Parliament's permission was unanimously repealed in 1716. 
Frederick, Prince of Wales, KG (Frederick Louis, German: Friedrich Ludwig; 31 January 1707 – 31 March 1751), was the eldest son and heir apparent of King George II of Great Britain. He grew estranged from his parents, King George and Queen Caroline .
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). He died aged 3 months, 4 days. A post-mortem was conducted to prove that he died from disease and not separation from his mother.
