The Etiquette of Royal Titles

Why the Duchess of Sussex is not referred to as “Princess Meghan”

Since marrying Prince Harry in May last year, Meghan's official title has been Her Royal Highness Princess Henry of Wales.

But the rules governing royal titles forbid the Duchess of Sussex from adopting the name Princess Meghan.

This is because tradition dictates that only those with royal blood are allowed to put 'prince' or 'princess' in front of their first name.

For example, the daughters of Prince Andrew are known as Princess Eugenie and Princess Beatrice because they are in the line of succession, rather than marrying in to the Royal Family.

Diana was given the title Princess of Wales as a courtesy but was never afforded the name 'Princess Diana' despite being referred to in this way by most of the public.

Similarly, Marie Christine Anna Agnes Hedwig Ida von Reibnitz - formally titled Princess Michael of Kent after marrying Prince Michael - is not called Princess Marie Christine. – Source The Daily Mail

Etiquette and Royal Baby Surnames

Prince Louis Arthur Charles Will Not Have a Last Name, ... but here are a few options in case he decides to use one: Mountbatten is Prince Phillip's surname, and Queen Elizabeth II's grandfather, King George V, took on Windsor—after Windsor Castle—as the British royal family's official surname in 1917, as Saxe-Coburg-Gotha sounded “too German” during World War I.

Most families pass down a last name from one generation to the next, but the British royal family follows their own rules and traditions. They have formal titles (some are made up of up to 15 words), but tend to only use Prince or Princess in front of their given name. However, following the birth of Prince William and Kate Middleton's third child, Prince Louis Arthur Charles, many are curious as to whether he will adopt the surname the descendants of Prince Phillip and Queen Elizabeth often use on certain occasions: Mountbatten-Windsor.

Royal historian, author and blogger of  “Royal Musings,” Marlene Eilers Koenig, said the baby will not. “The royal baby will not have a last name,” Koenig tells TownandCountrymag.com. “The name on the birth certificate will say HRH Prince or Princess, and all three names of Cambridge.” HRH is an abbreviation for His or Her Royal Highness. The three names of Cambridge refers to the three first names given to each royal child. For instance, Prince George’s three first names are George Alexander Louis, and Princess Charlotte's three first names are Charlotte Elizabeth Diana.

“The House name is Windsor and the family name for those who do use a surname is Mountbatten-Windsor,” Koenig adds. Mountbatten is Prince Phillip's surname, and Queen Elizabeth II's grandfather, King George V, took on the name “Windsor” —after Windsor Castle—as the British royal family's official surname in 1917. 

Prince George, the royal baby's oldest sibling, is listed at school with the surname Cambridge, which is part of his father and mother's official titles as the Duke and Duchess of Cambridge. Prince William and Prince Harry similarly adopted part of their father's title as their last name when they enlisted in the military under William Wales and Harry Wales, The Independent reports. Prince Charles is, of course, the Prince of Wales.– Town and Country Magazine, 2018
