Sophia of the Palatinate (commonly referred to as Sophia of Hanover; 14 October 1630 – 8 June 1714) was the Electress of Hanover from 1692 to 1698. Sophia, a granddaughter of James VI and I, died less than two months before she would have become queen; her claim to the thrones passed on to her eldest son, George Louis, Elector of Hanover, who ascended them as George I on 1 August 1714

"Queen Sophia Charlotte was queen consort of the United Kingdom and wife to King George III of Britain. She is a direct descendant of the Sousa family, a black branch of the Portuguese Royal House. Her appearance was black, with full lips and distinct facial features. Artists of the 18th century were asked to tone down “extreme” features of their subjects, but Sir Allan Ramsay, an anti-slavery artist, always painted Queen Charlotte in her actual appearance."
