The addition ofPrince Philipto the family brought about another name change, this one, the addition of Mountbatten, the last name he adopted after giving up his title of Prince of Greece and Denmark. The family explainson their websitethat the name Mountbatten-Windsor was officially declared in 1960, 13 years after Prince Philip marriedQueen Elizabeth.
“The effect of the declaration was that all The Queen’s children, on occasions when they needed a surname, would have the surname Mountbatten-Windsor,” they said. “For the most part, members of the Royal Family who are entitled to the style and dignity of HRH Prince or Princess do not need a surname, but if at any time any of them do need a surname (such as upon marriage), that surname is Mountbatten-Windsor.”

The reignited talk about Meghan and Prince Harry’s royal titles came amid the launch of theirnew website, Sussex.com, earlier this week.

At one point,Prince Harry got into an adaptive skito try a run for himself.
Capturing the moment, Meghan borrowed someone’s phone to snap a picture of her husband. She said she wanted to “show the kids,” according toHello!magazine reporter Rebecca Lewis.
