Princess Eugenie and Jack Brooksbank have welcomed their first child — and predictions for what they'll name the baby are still rolling in.

Now that it's been announced that the couple welcomed a son, both Betfair and Ladbrokes have Arthur as the top name contender. Ladbrokes have the odds set at 5/1, while Betfair set the odds at 8/1 before the baby's sex was announced.

Arthur is already a popular name within the British royal family, serving as a middle name for 2-year-old Prince Louis, Prince William and Prince Charles.

Ladbrokes has the father's name, James, as a close second with 6/1 odds. Frederick, Edward and Albert are in the running with 8/1 apiece, while 10/1 odds say the baby will be named Albert, Hugo or Alfred.

Betfair has Godfrey and Henry close behind at 10/1, while Thomas sits at 14/1 odds.

"Huge congratulations to Princess Eugenie and Jack Brooksbank on the birth of their son. The early betting is pointing towards a traditional name like Arthur for Eugenie and Jack's son," said Jessica O'Reilly of Ladbrokes. "However, given Eugenie's name we can't rule out something a little more out-there such as Tarquin or Humphrey."
