The Duke and Duchess of Cambridge appeared on the steps of the Lindo Wing, as is customary, to introduce their third child to the world.
The latest addition to the royal family was born at 11:01 am, on April 23, 2018. Coincidentally, on St. George's day and William Shakespeare's birthday.
As reported by The Sun, Prince William joked with the crowd, saying that he now has "thrice the worry." When asked about the baby's name, he informed the public that they "will find out sooner or later."
The announcement will be made in the coming days, and bookies across England are already taking bets as to what the fifth-in-line to the throne will be called.
According to Independent, Edward has 9 to 1 odds, while Arthur is leading the race with 2 to 1 odds. Other names include James, Jack, Fredrick, and Henry.
The name Henry could be a nod to Prince William's brother, Prince Harry, who is officially known as Prince Henry of Wales.
The name also has relevance when considered from a historical point of view. King Henry I ruled England from 1100 to 1135, and Henry II ruled from 1154 to 1189.
Similarly, if the name Edward is chosen, it could be as tribute to Prince Edward, Earl of Wessex, who is also Prince Charles' brother and Prince William's uncle.
The most popular option, Arthur, also has ties to the history of the British Royal Family. Prince Arthur William Patrick Albert of House Windsor was born to Queen Victoria and Prince Albert in 1850.
It could also refer to Arthur Tudor, Prince of Wales and Duke of Cornwall, born in 1486, who was the heir apparent of Henry VI.
Today, the titles of Prince of Wales and Duke of Cornwall belong to none other than the newborn baby's grandfather, Prince Charles.
Even though the reigning monarch, Queen Elizabeth, has four children, Prince William is the first future King in more than a century to welcome a third heir.
