Branchq,
That does not change the fact they are correctly known as HRH the Prince Andrew/Edward, Duke of York/Earl of Wessex.
Can you back that up? I would honestly like to see a link.
The sites I provided appear to say the contrary, that once the royal peerage is granted the title becomes simply HRH The Duke of York. These sites include the official court circular, the official website of Buckingham Palace, and now here is Debrett's
Debrett's Etiquette - Correct Forms Of Address
Royal Family
On 11 December 1917, it was ordained that "The children of any Sovereign of the United Kingdom and the children of any such Sovereign and the eldest living son of the eldest son of the Prince of Wales, shall have and at all times hold and enjoy the style, title, or attribute of Royal Highness with their titular dignity of Prince or Princess prefixed to their respective Christian names, or with their titles of honour; and that the grandchildren of the sons of any such Sovereign in the direct male line (save only the eldest living son of the eldest son of the Prince of Wales) shall have the style and title enjoyed by the children of Dukes."
It then lists how to write to the RF and it says, simply, 'The Duke of York'.
Branch you seem to be arguing against positions I don't hold - in this case, that I am arguing that the Duke of York is not or ceased to be a Prince. A royal Duke is always a Prince, by definition.
I am talking here about
titles.
Prince Andrew is never, ever styled HRH The Prince Andrew, Duke of York. Never. That is not a real title. He
is a Prince, and his name
is Andrew, and the day before his marriage he was styled HRH The Prince Andrew. However, on the day of his marriage, he was created Duke of York. It is incorrect to address a letter to him to 'HRH The Prince Andrew, Duke of York'. It is correct to address it to HRH The Duke of York. This is because the
royal dukedom of York, only ever held by a Prince, is a higher title than merely a Prince of the United Kingdom. A Prince of the United Kingdom who is
also a Royal Duke will use that title. Hence The Duke of Gloucester, not Prince Richard, Duke of Gloucester; hence The Duke of York, not Prince Andrew, Duke of York. All royal Dukes are Princes yet all use simply the royal ducal style.
If you click on the Debrett's link above and click on R for Royal Family it will give you the correct styles to use when writing to members of the Royal Family. It is HRH The Duke of York, not HRH Prince Andrew, Duke of York.
