If Prince Charles ascends the throne is it possible that the House of Windsor will become the House of Mountbatten, his father's naturalised family name?
I read that Queen Victoria was of the House of Hanover through her father Prince Edward, Duke of Kent. And that her son King Edward VII was of the House of Saxe-Coburg-Gotha through his father Albert, Prince Consort. Since children usually take the name of their father I'm under the assumption that Charles's accession will bring in the Mountbatten Dynasty.
Queen Victoria did indeed come from the House of Hanover and was the last Monarch of Hanoverian dynasty. When she married Albert of Saxe-Coburg and Gotha, she personally continued to belong to the House of Hanover; however, their children automatically took their father's surname (name of the House), thus establishing the short-lived House of Saxe-Coburg and Gotha (Edward VII was the only King to belong to it because his son, George V, changed the name of the House to Windsor).
As things are now, it is expected that Prince Charles will belong to the House of Windsor upon his accession to the Throne.
That is in accordance with the
Letters Patent of 1952, which declared that "I and My children shall be styled and known as the House and Family of Windsor, and that my descendants who marry and their descendants, shall bear the name of Windsor."
The declaration of 1960 stated that those of her and Prince Philip's descendants who do not have the style of Royal Highness and the title of Prince or Princess will bear the surname Mountbatten-Windsor. The latter obviously doesn't concern Prince Charles who is both a Prince and a Royal Highness.
However, it should be noted that the
dynastic name is entirely at the will of the Sovereign and any future Monarch can change it. Thus, Charles may chose to continue with the House of Windsor (as is expected), or opt to honour his father by changed the name of the Royal House to Mountbatten-Windsor or Windsor-Mountbatten, or even go for just Mountbatten.
