[quote alexdgr8]The Queen decided, with the consent of both Edward and Sophie, that any children the couple might have together would not be given the style His or Her Royal Highness, but instead be styled as children of an Earl. That makes Prince Edward’s children The Queen’s first male-line descendants not to have royal titles, and in accordance with Her Majesty’s 1960 Order-in-Council, they are the firsts to be allowed the proper use of the Mountbatten-Windsor family name.
As a result, their daughter is The Lady Louise Mountbatten-Windsor, as opposed to HRH Princess Louise of Wessex, and their son is James, Viscount Severn, who uses his father’s subsidiary title as a courtesy and is not HRH Prince James of Wessex.

They don’t use it, but according to their mother they have it...
Sophie opened up about why Louise and James do not have HRH titles in a rare interview last year.
She told The Times: "We try to bring them up with the understanding they are very likely to have to work for a living.
"Hence we made the decision not to use HRH titles.
"They have them and can decide to use them from 18, but I think it’s highly unlikely."
