Buckingham Palace is reportedly re-evaluating how to present Andrew’s name, aligning with the intentions of the late Queen.
Once his titles were revoked, Andrew was formally introduced as Andrew Mountbatten Windsor, notably omitting the hyphen usually seen in the royal family’s surname.
Authorities have stated that this naming style was mutually agreed upon with Andrew.
However, royal observers have disclosed that the Palace is reconsidering this decision, as it was noted that according to longstanding royal protocol, the name should be written as Mountbatten-Windsor.
This seemingly minor issue is significant as it directly relates to the legacy of the late Queen and her 1960 Privy Council declaration, which officially set the family surname for descendants who do not carry the titles of prince or princess.
Just two weeks prior to Andrew’s birth, the then-Queen signed an official notice that appeared in The London Gazette.
It stated: ‘Now therefore I declare My Will and Pleasure that, while I and My children shall continue to be styled and known as the House and Family of Windsor, My descendants other than descendants enjoying the style, title or attribute of Royal Highness and the titular dignity of Prince or Princess and female descendants who marry and their descendants shall bear the name of Mountbatten-Windsor.’
The name was created to incorporate Philip Mountbatten’s surname into the Windsor line, a symbolic move reflecting the Queen’s marriage and the continuing link between her family and her husband’s.
That 1960 declaration meant that Andrew, who was born soon after, was the first royal baby officially registered with the Mountbatten-Windsor surname.
After his titles were stripped, the ex-Duke was reintroduced to the world as Andrew Mountbatten Windsor – notably missing the hyphen traditionally used in the royal family’s double-barrelled surname
Now that he no longer holds the title of Prince or the style of His Royal Highness, many historians believe it is appropriate for him to revert to the precise version laid out by his mother’s decree – with a hyphen.
Royal historian and author Ian Lloyd told The Times they were surprised the Palace had ever published his name without one, given the ‘historic precedent’ and the legal wording of the Queen’s notice.
Examples of the hyphenated name appear on numerous royal documents. On Princess Anne’s 1973 marriage certificate, her full name is written as Anne Elizabeth Alice Louise Mountbatten-Windsor, a Princess of the United Kingdom of Great Britain and Northern Ireland.
The same styling appeared on the 2019 birth certificate of Harry and Meghan’s son, Archie Harrison Mountbatten-Windsor.
But the Palace has not always been entirely consistent with punctuation when it comes to royal names.
Even among the aristocracy, hyphens come and go – sometimes depending on tradition, preference, or even space on official forms.
The late Queen Mother, for instance, was known as Elizabeth Bowes-Lyon on formal documents, but the hyphen was often dropped in day-to-day use, with newspapers and royal announcements regularly referring to her as Elizabeth Bowes Lyon.
Other well-known names such as Andrew Parker Bowles and Helena Bonham Carter also forgo the hyphen despite being double-barrelled, while the composer Andrew Lloyd Webber never used one at all.
However, the Mountbatten-Windsor case is expected to be treated differently because it stems directly from an official royal declaration rather than personal style.
According to royal sources, Buckingham Palace may now begin using the hyphenated form in all future references to Andrew’s name.
