The Queen shares her love for horses, as does she. She also bears some resemblances to her great-grandmother who was her grandmother when she was growing up.

When she arrived in her car to attend the wedding of the Duke and Duchess Sussex in 2018, the playful fourth-in-line to the throne slung out her tongue.

Archie, who was placed in 2019 and is now living thousands of kilometers away from California. This comes after Harry and Meghan became senior royals and moved to America.

Archie was born in 2019 and lives in California, thousands of miles from where he and his parents, Harry & Meghan, moved to the USA last year.

It appears that he inherited the red hair of his father, which was evident when he was photographed in stylised images on the Christmas card.

Oprah interviewed Meghan about Meghan accusing a royal member of raising concerns prior to Archie’s birth over how dark her skin might have been.

Archie did not become a prince due his race. However, he does not have the rights to be a Prince or to an HRH title yet. This is because King George V established rules over 100 years ago.

9. August Brooksbank

11.  Lilibet Diana Mountbatten-Windsor

12. Sienna Elizabeth Mapelli Mozzi 

Prince Andrew and Sarah Ferguson’s oldest child, Princess Beatrice (33), gave birth at 11.42pm Saturday, 18 September to 6 lbs 2oz. 

Edo Mapelli Mozzi, her husband, has named their child Sienna Elizabeth as a tribute to the Queen. 

Although Sienna’s mother is a princess she will not be able to claim a title of royal. The styling of HRH is only available to grandchildren who are descendants of the monarch via the male line. She will therefore be called Miss Mapelli Mozzi. Although the Queen may bestow a title to her great-grandchild, this is not likely.
