British royalty, a granddaughter of George III. She married into the Grand Ducal House of Mecklenburg-Strelitz and became the Grand Duchess of Mecklenburg-Strelitz.
Her full name was Augusta Caroline Charlotte Elizabeth Mary Sophia Louise.
Princess Augusta had one brother, Prince George, later 2nd Duke of Cambridge; and one sister, Princess Mary Adelaide, later Duchess of Teck. As such, Princess Augusta was a first cousin of Queen Victoria and aunt to Mary of Teck, later consort of George V.
On 28 June 1843, Princess Augusta married her first cousin, Frederick William of Mecklenburg-Strelitz, at Buckingham Palace, London. (The two were also second cousins on their fathers' side.) Upon marriage, Augusta became HRH The Hereditary Grand Duchess of Mecklenburg-Strelitz and, on 6 September 1860, HRH The Grand Duchess of Mecklenburg-Strelitz following the death of her father-in-law. The marriage of the Grand Duke and Grand Duchess produced two children.
The Dowager Grand Duchess of Mecklenburg-Strelitz died on 5 December 1916 in Neustrelitz, Germany. At the time of her death, she was 94 years, 4 months and 16 days old, making her the longest-lived British Princess of the Blood Royal until Princess Alice, Countess of Athlone, a male-line granddaughter of Queen Victoria, broke the record in 1977, aged over 97 years old.
