Prince George, Duke of Kent, {'1': ", '2': ", '3': ", '4': "} (George Edward Alexander Edmund; 20 December 1902 – 25 August 1942) was the fourth son of George V of the United Kingdom and Queen Mary.
The August 1942 Dunbeath Air Crash involved the loss of a Mark 3 Short S.25 Sunderland that crashed in the Scottish Highlands on a headland known as Eagle's Rock near Dunbeath, Caithness on 25 August 1942.
 The crash killed 14 of 15 passengers and crew, including HRH Prince George, Duke of Kent who was on duty as an Air Commodore in the Royal Air Force on a mission to Reykjavik; a loss keenly felt by the British Prime Minister.
 A Royal Air Force Board of Inquiry determined that the crash was the result of a navigational error by the crew.
Viscount Ullswater, of Campsea Ashe in the County of Suffolk, is a title in the Peerage of the United Kingdom.
 It was created in 1921 for James Lowther upon his retirement as Speaker of the House of Commons.
 He was the eldest son of the Hon. William Lowther, third son of the Hon. Henry Lowther, second son of William Lowther, 1st Earl of Lonsdale (see Earl of Lonsdale and Lowther Baronets for earlier history of the family).
 The first Viscount lived to the age of 93, and was pre-deceased by both his eldest son the Hon. Christopher Lowther, a Conservative politician, and his eldest son's eldest son John Arthur Lowther (1910–1942) (who was Private Secretary to Prince George, Duke of Kent and was killed in the same air crash as him), the title being inherited by his seven-year-old great-grandson, the second and current Viscount, in an extremely rare instance of a great-grandson succeeding his great-grandfather in a peerage.
 The second Viscount held office in the Conservative administrations of Margaret Thatcher and John Major and since 2003 he is one of the ninety elected hereditary peers that remain in the House of Lords after the passing of the House of Lords Act 1999.
 As a descendant of the first Earl of Lonsdale he is also in remainder to this peerage and its subsidiary titles.
 The current holder of the earldom, Hugh Lowther, 8th Earl of Lonsdale, is Lord Ullswater's fourth cousin.
The Little Baldon air crash occurred on 6 July 1965 when a Handley Page Hastings C1A transport aircraft operated by No. 36 Squadron Royal Air Force, registration TG577, crashed into a field in Little Baldon, near Chiselhampton, Oxfordshire, shortly after taking off from RAF Abingdon.
 The flight was captained by Flt Lt John Akin.
 All 41 people aboard, including six crew, perished in the crash, making it the third worst air crash in the United Kingdom at the time.
The Casket letters were eight letters and some sonnets said to have been written by Mary, Queen of Scots, to the Earl of Bothwell, between January and April 1567.
 They were produced as evidence against Queen Mary by the Scottish lords who opposed her rule.
 In particular, the text of the letters was taken to imply that Queen Mary colluded with Bothwell in the murder of her husband, Lord Darnley.
 Mary's contemporary supporters, including Adam Blackwood dismissed them as complete forgeries or letters written by the Queen's servant Mary Beaton.
 The authenticity of the letters, now known only by copies, continues to be debated.
 Some historians argue that they were forgeries concocted in order to discredit Queen Mary, and ensure that Elizabeth I supported the kingship of the infant James VI of Scotland, rather than his mother.
 The historian John Hungerford Pollen, in 1901, by comparing two genuine letters drafted by Mary, presented a subtle argument that the various surviving copies and translations of the casket letters could not be used as evidence of their original authorship by Mary.
Queen Mary University of London (QMUL) is a public research university in London, England, and a constituent college of the federal University of London.
 It dates back to the foundation of London Hospital Medical College in 1785.
 Queen Mary College, named after Mary of Teck, was admitted to the University of London in 1915 and in 1989 merged with Westfield College to form Queen Mary and Westfield College.
 In 1995 Queen Mary and Westfield College merged with St Bartholomew's Hospital Medical College and the London Hospital Medical College to form the School of Medicine and Dentistry.
 The Medical College of the Royal London Hospital (now part of Barts and The London School of Medicine and Dentistry) was England’s first medical school when it opened in 1785.
Lady Mary Compton (1669 – 6 August 1691), later Mary Sackville, Countess of Dorset, was a member of Queen Mary II's court.
 She was one of the Hampton Court Beauties painted by Sir Godfrey Kneller for Queen Mary.
 She was Lady of the Bedchamber to Queen Mary II.
The history of Queen Mary University of London lies in the mergers, over the years, of four older colleges: Queen Mary College, Westfield College, St Bartholomew's Hospital Medical College and the London Hospital Medical College.
 In 1989 Queen Mary merged with Westfield College to form "Queen Mary & Westfield College".
 Although teaching began at the London Hospital Medical College in 1785, it did not become part of Queen Mary until 1995.
 In that same year the two medical schools merged to form the School of Medicine and Dentistry at Queen Mary & Westfield College.
The Vyne Community School, Basingstoke was created out of the merger of two pre-existing schools, Queen Mary's School for Boys, Basingstoke a selective Grammar School, also known as QMSB, and Charles Chute Secondary Modern School, which occurred in 1970.
 Initially the school was known as Queen Mary's & Charles Chute School, and was the result of the U.K. Government's policy in the 1960s to make all maintained (state funded) schools comprehensive.
 In the first instance the school remained a single sex institution, becoming coeducational in 1971-72.
 The name "Queen Mary's" was later transferred to the Queen Mary's College, a Sixth Form College, in Cliddesden Road, Basingstoke.
 The school was thereupon renamed The Vyne School, in commemoration of the links that both schools had to The Vyne, a property owned by the National Trust for Places of Historic Interest or Natural Beauty, former home of the Sandys and Chute families, just North of Basingstoke.
