She was Portugese Royalty

With features as conspicuously Negroid as they were reputed to be by her contemporaries, it is no wonder that the black community, both in the U.S. and throughout the British Commonwealth, have rallied around pictures of Queen Charlotte for generations. They have pointed out the physiological traits that so obviously identify the ethnic strain of the young woman who, at first glance, looks almost anomalous, portrayed as she usually is, in the sumptuous splendour of her coronation robes.

Queen Charlotte, wife of the English King George III (1738-1820), was directly descended from Margarita de Castro y Sousa, a black branch of the Portuguese Royal House. The riddle of Queen Charlotte’s African ancestry was solved as a result of an earlier investigation into the black magi featured in 15th century Flemish paintings. Two art historians had suggested that the black magi must have been portraits of actual contemporary people (since the artist, without seeing them, would not have been aware of the subtleties in colouring and facial bone structure of quadroons or octoroons which these figures invariably represented) Enough evidence was accumulated to propose that the models for the black magi were, in all probability, members of the Portuguese de Sousa family. (Several de Sousas had in fact traveled to the Netherlands when their cousin, the Princess Isabella went there to marry the Grand Duke, Philip the Good of Burgundy in the year 1429.)
