Now that the wait for Meghan Markle and Prince Harry’s royal baby is finally over, a list of potential baby names for their firstborn son is narrowing down.

“We are pleased to announce that Their Royal Highnesses The Duke and Duchess of Sussex welcomed their firstborn child in the early morning on May 6th, 2019. Their Royal Highnesses’ son weighs 7lbs. 3oz,” the couple’s statement on Instagram read.

Meghan and Harry didn’t reveal the name they chose for the baby and Harry told reporters that they hadn’t yet settled on one.

"The baby is a little bit overdue so we've had a little bit of time to think about it. That's the next bit," he teased, confirming he and Meghan will make their debut as a family in two days "as planned."

At 5/1 odds, the company believes Meghan and Harry will opt for a more traditional name for the infant despite often shaking up royal tradition with modern touches. Arthur is one of the middle names of Prince Charles, the baby’s grandfather.

In second place, at 6/1 odds, are Albert and Philip, the latter being the name of Queen Elizabeth’s husband, the Duke of Edinburgh. Following them are James at 8/1, Alexander and Alfred at 10/1 and Thomas coming in fourth at 12/1.
