It’s a boy! But what will his name be?

Frenzied speculation has been the order of the day since Meghan, Duchess of Sussex, gave birth to a baby boy early on Monday morning. The child will be seventh in line to the British throne.

Dad Prince Harry spoke to the media shortly after, but there was no sign of Meghan or the latest royal. The whole family is expected to put in a public appearance later today, and announce the baby’s name.

Alexander Odds on Favorite

Bookmakers love to take bets on baby names. They certainly made good profits three times over the births of Prince William and his wife Kate’s children.

Alexander seems to be the top choice for Harry and Meghan’s son. Several bookmakers are running short odds on this name – SkyBet are offering odds of 9/2, while Ladbrokes and Betfred are both at 4/1. Paddy Power, Unibet and Betfair are all offering odds of 7/2.

Spencer is running a close second, with odds only slightly behind those for Alexander. Spencer, of course, is a family name for Harry – his late mother Princess Diana was Lady Diana Spencer before she married Prince Charles in 1981. Naming the boy Spencer would be a fitting tribute, and odds are 6/1 at Bet365, but 4/1 at both Ladbrokes and William Hill.

Leading Sky News journalist Kay Burley, who has covered royal news many times, has stuck her neck out and declared the baby will be named Alexander Philip Charles – let’s see if she’s right later today.

Arthur, or Not?

Ladbrokes said on Monday, after the birth, that Arthur was the top pick – it is a popular royal name – and it was offering odds of 5/1. Today, however, those odds have drifted to 6/1. Betfred is touting odds of 7/1. So, even though it’s one of Prince Charles’ middle names, it’s looking less likely.

The royals love tradition, so other names such as Philip (for great-grandfather Prince Philip), Albert (Queen Victoria’s consort) and James (the name of several British kings) are all in the running. Quite a few bookmakers are offering odds of 4/1 on James. Philip and Albert seem less popular, with odds of anywhere from 6/1 to 10/1. Only Betway is sticking to its guns for Albert at 7/2.

Not Donald or Boris

The British love to stick their necks out when picking choices for royal baby names. The biblical Noah is attracting odds of 11/1 on Paddy Power, which is also offering 25/1 on Elton. Gregory has attracted odds of 50/1 on Skybet and 30/1 on Unibet.

Don’t waste your money on Donald (Trump) or Boris (Johnson) – either of these are attracting very high odds of between 250/1 and 500/1 across most of the bookmakers right now.

And if none of those takes your fancy, you can always place bets on the young prince’s future – several bookmakers are already publishing odds on whether he will marry before Princess Charlotte does, what his exam results will be and even whether he will go bald before Prince Louis.
