Royal baby name: Is there an odds-on favorite?

CNN  — 

The Royal Baby Name Game is underway.

After the Duchess of Cambridge gave birth to her second child on Saturday, attention turned to name possibilities for the newborn princess.

As one Twitter user noted, “royal baby” might make for a great hashtag, but it’s really not the best name for a child.

Alice, Charlotte and Olivia jockeyed for the top three spots after Catherine gave birth, switching positions throughout Saturday on various betting websites. By Sunday, Alice and Charlotte emerged neck and neck as the favorites, followed closely by Victoria and Elizabeth, according to gaming site Ladbrokes.

The Duchess of Cambridge shows off her newborn daughter.

Alice was the name of one of Queen Victoria’s daughters and of the mother of the Duke of Edinburgh, the baby’s great-grandfather. Charlotte, a feminine form of Charles, could be chosen as a nod to her grandfather, Prince Charles, Prince William’s father.

Dynastic names Elizabeth and Victoria are popular picks on social media. Diana is the sentimental favorite, although there are many arguments against bestowing the name upon the new princess.

Others cheekily held out hope for unconventional names like Beyonce and Barbara, because apparently, Barbara is an “unsuitable” name for a royal.

Twitter also had fun with names that should never, ever be considered. Names of characters from “Game of Thrones” dominated this category, with the odds against anyone from the House of Lannister. For the record, the odds are better for Arya, 100 to 1, than Daenerys or Cersei, both 1,000 to 1.

Whatever William and Kate pick, there will be plenty of room for multiple names, if their firstborn son’s full name is any precedent: George Alexander Louis.

In that instance, predictions that the couple would stick to tradition proved accurate.
