Prince Harry and Meghan Markle wedding: Will the bride really be our first mixed-race royal?

When Prince Harry and American actress Meghan Markle announced their engagement on Monday, Twitter erupted with the news that the newest princess in the royal family would be bi-racial.

“We got us a Black princess ya'll,” GirlTyler exulted. “Shout out to Prince Harry and Meghan Markle. Their wedding will be my Super Bowl.”

But Markle, whose mother is black and whose father is white, may not be the first mixed-race royal.

Some historians suspect that Queen Charlotte, the wife of King George III who bore the king 15 children, was of African descent.

Historian Mario De Valdes y Cocom argues that Queen Charlotte was directly descended from a black branch of the Portuguese royal family: Alfonso III and his concubine, Ouruana, a black Moor.

In the 13th century, “Alfonso III of Portugal conquered a little town named Faro from the Moors,” said Valdes, a researcher for Frontline PBS. “He demanded [the governor's] daughter as a paramour. He had three children with her.”

According to Valdes, one of their sons, Martin Alfonso, married into the noble de Sousa family, who also had black ancestry. Queen Charlotte had African blood from both families.

Valdes, who grew up in Belize, began researching Queen Charlotte's African ancestry in 1967, after he moved to Boston.

“I had heard these stories from my Jamaican nanny,” Valdes recalled.

He discovered that a royal physician, Baron Christian Friedrich Stockmar, described Queen Charlotte as “small and crooked, with a true mulatto face.”

Sir Walter Scott wrote that she was “ill-coloured” and called her family “a bunch of ill-coloured orangutans.”

One prime minister once wrote of Queen Charlotte: “Her nose is too wide and her lips too thick.”

In several British colonies, Queen Charlotte was often honoured by blacks who were convinced from her portraits and likeness on coins that she had African ancestry.

Valdes became fascinated by official portraits of Queen Charlotte in which her features, he said, were visibly “negroid.”

“I started a systematic genealogical search,” said Valdes, which is how he traced her ancestry back to the mixed-race branch of the Portuguese royal family.

Charlotte, who was born 19 May 1744, was the youngest daughter of Duke Carl Ludwig Friedrich of Mecklenburg-Strelitz and Princess Elisabeth Albertine of Saxe-Hildburghausen. She was a 17-year-old German princess when she travelled to England to wed King George III, who later went to war with his American colonies and lost rather badly. His mother most likely chose Charlotte to be his bride.

“Back in London, the king's enthusiasm mounted daily,” wrote Janice Hadlow in the book, A Royal Experiment: The Private Life of King George III. “He had acquired a portrait of Charlotte and was said to be mighty fond of it, but won't let any mortal look at it.”

King George III ordered that gowns be made and waiting for his new bride when she arrived in London.

He met Charlotte for the first time on their wedding day, 8 September 1761.

“Introduced to the king, Charlotte 'threw herself at his feet, he raised her up, embraced her and led her through the garden up the steps into the palace,' ” Hadlow wrote. “Some later reminiscences asserted that at the moment of their meeting, the king had been shocked by Charlotte's appearance.”

In a portrait painted by Sir Allan Ramsay, Queen Charlotte's hair is piled high in curly ringlets. Her neck is long and her skin appears to be café-au-lait.

Ramsay, Valdes said, was an abolitionist married to the niece of Lord Mansfield, the judge who ruled in 1772 that slavery should be abolished in the British Empire. And Ramsay was uncle by marriage to Dido Elizabeth Lindsay, the black grand-niece of Lord Mans field. Dido's life story was recently recounted in the movie, Belle.

In 1999, The Sunday Times published an article with the headline: “REVEALED: THE QUEEN'S BLACK ANCESTORS.”

“The connection had been rumoured but never proved,” The Times wrote. “The royal family has hidden credentials that make its members appropriate leaders of Britain's multicultural society. It has black and mixed-raced royal ancestors who have never been publicly acknowledged. An American genealogist has established that Queen Charlotte, the wife of George III, was directly descended from the illegitimate son of an African mistress in the Portuguese royal house.”

Some scholars in England dismissed the evidence as weak - and beside the point.

“It really is so remote,” said David Williamson, co-editor of Debrett's Peerage, the guide to Britain's barons, dukes and duchesses, marquises, and other titled people. “In any case, all European royal families somewhere are linked to the kings of Castile. There is a lot of Moorish blood in the Portuguese royal family and it has diffused over the rest of Europe. The question is, who cares?”

After The Times story, The Boston Globe hailed Valdes' research as groundbreaking. Charlotte, who died in 1818, passed on her mixed-race heritage to her granddaughter, Queen Victoria, and to Britain's present day monarch, Queen Elizabeth.

A Buckingham Palace spokesman did not deny Queen Charlotte's African ancestry. Spokesman David Buck told The Globe: “This has been rumoured for years and years. It is a matter of history, and frankly, we've got far more important things to talk about.”
