Royal titles Prince Louis, Archie and James, Viscount Severn will receive in the future

Prince Louis

In recent centuries, the second son of the monarch has traditionally been awarded the Duke of York title.

The current holder is Prince Andrew, the Queen’s second son, but he has two daughters and will not be able to pass his title on to them.

With reference to the Letters Patent issued by the Queen decreeing Prince Andrew’s Duke of York title in 1986, royal historian Marlene Koenig highlighted how it is phrased to include Andrew and “the heirs male of his body lawfully begotten”.

Ms Koenig explained: “Andrew’s peerages will revert to the Crown when he dies – and at some point, the Sovereign could create a new Dukedom of York for Prince Louis, perhaps, if Andrew is dead by the time Louis marries.”

When Prince William is King, he may wish for his youngest child to have a different royal title, and there are some vacant dukedoms available.

Although Prince Harry was given the Dukedom of Sussex, other contenders at the time included the dukedoms of Clarence, Connaught, Kendal, Ross and Windsor.

James, Viscount Severn

James, Viscount Severn was born in 2007 to Prince Edward and Sophie, Countess of Wessex.

James is not styled as a Prince, although he is entitled to be, and instead uses his father’s subsidiary title as a courtesy.

But when Prince Edward dies, James will likely inherit his Earldom of Wessex.

If Prince Charles gives Edward the Dukedom of Edinburgh, as is expected when he is King, James may also one day inherit the Duke of Edinburgh title his grandfather made so famous.
