Meghan Markle and Prince Harry may have just shared the news of their pregnancy, but that hasn’t stopped gamblers from placing bets on the second’s name.

Many speculate that the pair will pay tribute to Harry’s late mother, Princess Diana by naming a girl Diana or a boy Spencer (her last name). Betfair has 10/1 odds for Diana and 25/1 for Spencer. Ladbrokes as Diana at 6/1 and Spencer at 10/1. The pair made the announcement on Valentine’s Day, a tribute in of itself to Diana, who announced her second pregnancy (it was Harry!) in 1984.

Other top bets, via People: Alfie and Alexandra top the leaderboard at Ladbrokes with 4/1 odds, while Betfair places Arthur (10/1), Thomas (12/1) and Isabella (12/1) with the highest odds.

Ladbrokes has Doria, after Meghan's mother, in consideration with 12/1 odds, along with Emily (10/1), Sebastian (12/1), Marina (12/1) and Willow (14/1).

Betfair spokesperson Sam Rosbottom told People: “Having picked Archie — a name that wasn't even on our list, for their first child — the odds suggest Meghan & Prince Harry could opt for a more traditional name for their second with Arthur and Diana the joint 8/1 favorites with Betfair.”

Meghan and Harry’s firstborn Archie will turn 2 on May 6th.
