Here's why Allegra is surging in popularity as the royal baby name

And it's actually all for a very moving reason.

Meghan Markle and Prince Harry are expecting the birth of their first child together any day now, with the whole world waiting for the announcement of the royal baby.

Since revealing that they were expecting, Meghan and Harry have been getting everyone excited, referring to their future arrival as ‘our little bump‘ and explaining how thrilled they are to ‘join the parenting club’.

Understandably the most discussed subject around Baby Sussex is the due date, with the couple announcing that they will be keeping the birth a secret for a few days in order to celebrate in private before making the news public, something that has only prompted more speculation.

Yes, everyone is talking about Baby Sussex - and until we know when they will arrive, it’s the baby name predictions that are making the most news.

The royal baby will be seventh in line to the throne, so it is unlikely that Prince Harry and Meghan Markle will have to conform to as many rules as William and Kate, but it was still originally thought that the Duke and Duchess of Sussex would opt for a traditional moniker.

The most popular names according to William Hill? Victoria, Elizabeth and Diana.

It was revealed this week however that there’s another moniker that could be in the running and we would never have called it.

The name? Allegra.

Yes, really.

Allegra has surged in popularity according to Ladbrokes, with reports that the moniker has shot from 100/1 to 12/1 in the last 24 hours.

But why Allegra? Well, there’s actually a very sweet reason behind it.

According to the Daily Mail, Princess Diana was a fan of the name Allegra, reportedly wanting to use the moniker if she ever had a daughter of her own.

Well that’s just lovely.
