Princess Charlotte of Mecklenburg-Strelitz (Sophia Charlotte; 19 May 1744 – 17 November 1818) was the wife of King George III. She was Queen of Great Britain and Ireland from their marriage until the union of the two kingdoms in 1801, after which she was Queen of the United Kingdom. She was the first Black Queen of England. Charlotte was the eighth child of the Prince of Mirow, Germany, Charles Louis Frederick, and his wife, Elisabeth Albertina of Saxe-Hildburghausen. In 1752, when she was eight years old, Sophie Charlotte's father died. As princess of Mecklenburg-Strelitz, Sophie Charlotte was descended directly from an African branch of the Portuguese Royal House, Margarita de Castro y Sousa. Six different lines can be traced from Princess Sophie Charlotte back to Margarita de Castro y Sousa. She married George III of England on September 8, 1761, at the Chapel Royal in St James’s Palace, London, at the age of 17 years of age becoming the Queen of England and Ireland. Well I never knew that! Edit: according to Wiki, any African ancestry is unproven
