Sounds a little unlikely:
In spite of its roots, we are apparently still perfectly comfortable using the phrase, even though royal blood has probably been mixed for centuries. There have been Africans throughout Europe since at least Roman times, and marriages between European royals, with their fondness for black servants, slaves and extramarital reproduction, make it unsurprising that Queen Charlotte, wife of George III – described, in an era when slaves were omnipresent, as “ugly”, with a dark complexion and flared nostrils – may well have had some African heritage.
Chattel slavery of negroes was actually rather uncommon in Northern Europe. Very uncommon in fact. Especially in insignificant German Duchies. As we’re told:
Claims of African ancestry
Margarida de Castro e Sousa genealogy and descent.
In a 2009 episode of the PBS TV magazine, Frontline, Mario de Valdes y Cocom claimed that Charlotte may have had African ancestry and speculated that Scottish painter Allan Ramsay emphasized the Queen’s alleged “mulatto” appearance in his portrait of her to support the anti-slave trade movement.
Valdes incorrectly said that an early-19th-century medical practitioner, Baron Stockmar, was Queen Charlotte’s personal physician and that he had described the Queen as having a “mulatto face” in his autobiography. In fact, Christian Friedrich Freiherr von Stockmar was personal physician not to Queen Charlotte, but to Prince Leopold of Saxe-Coburg-Gotha in 1816, at the time of Leopold’s marriage to Princess Charlotte of the United Kingdom.
On the PBS website page for this episode, Valdes interprets an excerpt of a poem reproduced there as attesting to Charlotte’s African features, but it clearly refers to her as descended from the Vandals, an East Germanic tribe.
According to Valdes, Queen Charlotte’s African contribution could have been inherited three to six times over from one ancestor nine generations removed, Margarida de Castro e Sousa, a 15th-century Portuguese noblewoman, who traced her ancestry to King Afonso III of Portugal (1210–1279) and one of his mistresses, Madragana (c. 1230–?). Critics of Valdes’ theory point out that Margarita’s and Madragana’s distant perch in the queen’s family tree – nine and 15 generations removed, respectively – makes any African ancestry that they bequeathed to Charlotte negligible. in any event, Charlotte shared descent from Alfonso and Madragana with a large proportion of Europe’s royalty and nobility.
Madragana was perceived by Valdes as African because she was described as a Moor by a single author. This is denied by most other authors, that point out that Madragana was most likely a Mozarab: an Iberian Christian living in the Iberian Peninsula when it was under Muslim control.
So might Queen Philippa, wife of Edward III, described as having broad nostrils and a wide mouth, and as being “brown of skin all over”.
Belgians? Not really, no. 12th century Belgians?
And then we get to the real point here:
If Harry was previously oblivious to the complex world of race and identity, he’s about to get a crash course. News of his latest relationship threatens to bring Britain’s simmering, unresolved issues with the myth of royal racial purity into the open. Markle may have found peace in the grey spaces of mixed identities, and has spoken of both her positive experience of blackness and the negative – seeing her mother called the N-word, and being passed over for acting roles by an industry that regarded her as too black to play a white role and too white to play a black one.
Nobody’s going to give a fuck. Damn, if we can accept the Middleton’s there’s nowt to worry about, is there?
