Mamma Meghan, here we go again.

The Duke and Duchess of Sussex's baby has arrived — with the newborn boy, who was born at 5.26 a.m. on Monday, now seventh in line to the throne. 

Prince Harry confirmed that the baby is due to be "presented" to the media in two days time.

"This is definitely my first birth," said Prince Harry, when asked what it was like being present when his baby was born. "It was amazing, absolutely incredible, and, as I said, I'm so incredibly proud of my wife."

"As every father and parent will ever say, you know, your baby is absolutely amazing, but this little thing is absolutely to-die-for, so I'm just over the moon," he added. "It's been the most amazing experience I could ever have possibly imagined. How any woman does what they do is beyond comprehension."

But the baby is yet to be named. So taking some inspiration from some of the world's greatest activists, we've got a few ideas for the couple for what to call their first child.

1. Stephen

World-famous scientist and physicist Stephen Hawking died aged 76 in March last year. But while he lived, he changed how we saw the whole universe — and through sheer force of will and a fierce sense of humour, he taught the world the vital importance of science.

Now more than ever, it might be useful to remind the world what he stood for.

2. Pravin

In India, they call Pravin Nikam the “Period Man”, because he wants to put a full stop to the stigma around menstrual hygiene.

“Why has something as natural as breathing been relegated to the status of an unmentionable taboo?” Nikam asked at Global Citizen Live in New York. “Maybe it is because 50% of the world’s population remains unaware of the importance of menstrual hygiene.”

And when Meghan and Harry said that, instead of wedding gifts, they would rather donations be made in their name to charities, one of the seven they named works to combat period stigma in Mumbai. 

It's a match made in heaven. 

3. Leo

If Kensington Palace tweeted that a royal baby was named after Leonardo DiCaprio, the internet would break.

DiCaprio is a UN Messenger for Peace, has donated over £14 million in grants to environmental projects, made a documentary on climate change, and even helped pay off the debt of Seychelles to create marine reserves and protect the ocean. It turns out the queen wants to stop climate change, too.

Let’s melt hearts before the planet, please.

4. Nelson

Nope, not the school bully on "The Simpsons."

Former president of South Africa and anti-apartheid revolutionary Nelson Mandela was one of the greatest activists of all time. There’s already a statue of him in Parliament Square, and he hit us with this corker in London, when he made a speech here 13 years ago:

“Like slavery and apartheid, poverty is not natural,” Mandela said. “It is man-made and it can be overcome and eradicated by the actions of human beings.”

5. Bill

Regal names are rarely imaginative.

Britain has had eight kings called Edward or Henry, and six named George. And the next most popular name? William.

Which, conveniently, just so happens to be the name of the humanity’s biggest philanthropist (and most admired man) Bill Gates.

Gates runs the world’s largest private charity with wife Melinda (save that name for the next one), and has donated over £30 billion to worthwhile causes.

And Bill Gates’ full name? William Henry Gates III. Two words: copy and paste.

6. George

Meghan and Harry's friendship with Amal and George Clooney has been well-documented. So is it too much to ask that they'd name their baby after Amal's apparently quite famous husband? 

As role models go, the Clooney's are an inspirational power couple. Amal is a human rights lawyer, and has addressed head-on some of the world’s most disturbing human rights abuses — including supporting Nadia Murad in advocating for the rights of the Yazidi people. And George has been instrumental in supporting her, while leading from the front on activism for refugees, migrants, and oppressed people everywhere.

Forget about Prince George, the new kid's first cousin. The royal baby would share a birthday with real George Clooney! This is an opportunity that cannot be missed.
