Royals usually give the baby 4 names, so my guess would be Philip Christopher Edward George.

I picked Philip since Edward will take over the title of Duke of Edinburg from his father one day.

Since the little guy was born close to George VI’s birthday (Dec. 14), my guess is he will have either Albert or George in his name.

George VI was the Queen’s father and he was dearly loved.

My other guesses, Edward, Philip and Christopher for Sophie’s dad.

Titles and styles
* 8 November 2003 –: The Lady Louise Windsor
o Legally: Her Royal Highness Princess Louise of Wessex

As a granddaughter of the monarch in the male line, she is legally Her Royal Highness Princess Louise of Wessex, not Lady Louise Windsor, and, when she comes of age, she may legally use the title Princess Louise, if she wishes.[5] However, when her parents married, they decided that their children would be styled as the children of an earl rather than as princes or princesses with the style Royal Highness. This was intended to reduce the burden of royal titles and the responsibility that comes with them. In the absence of letters patent, Lady Louise legally remains a Princess of the United Kingdom, regardless of how she is styled.

Although her last name is Mountbatten-Windsor she is styled only using the surname Windsor

I believe Louise’s title of Lady instead of Princess was her parents’ choice (sophie and edward) Just as Princess Anne chose not to give her two children titles at all. I read somewhere that in that case, Princess Anne chose for her children to just have regular first and last names, no titles – to try to give them a sense of normalcy.

why does Louise have a “Lady” title and not princess? Prince Andrew’s kids are princess.

Viscount Severn will be the little man’s title if his parents choose for him to carry a title. They declined for Louise to be known as Princess Louise. She is “just” Lady Louise Windsor in contrast to Princess Beatrice and Princess Eugenie.

sorry for bad news. Vicomt Severn is a title.

Apparently, the baby boy first name would be Severn. To be confirmed however.

She had the baby today…. A BABY BOY! 6 lbs 10 oz…. same hospital she was in when she had Louise….

the BBC have just announced that the Countess gave birth today, by c-section – to a boy. No other details released as yet!
