Meet the other US-born British royal – the daughter of a Windsor and an actress
Watch: Prince Harry and Meghan Welcome Baby Daughter!
Prince Harry and Meghan Markle have welcomed their second child, a girl named Lilibet Diana, born in California, USA.
While it's very unusual for a member of the British Royal Family to be born outside the UK, she is not the first.
Maud Windsor, the oldest daughter of Lord and Lady Frederick Windsor, was born in Los Angeles on 15 August, 2013.
Maud's mother is better known as Sophie Winkleman, famous for her roles in Peep Show and Two And A Half Men.
And it was while the couple lived in California during the filming of the latter programme that she gave birth to Maud in the Ronald Reagan UCLA Medical Center.
Lord Frederick Windsor is the son of Prince and Princess Michael of Kent. Prince Michael is one of the Queen's cousins, but the couple don't carry out royal duties.
However they do live in Kensington Palace, and have represented the Queen on a handful of trips abroad over the years.
Maud's full name is Maud Elizabeth Daphne Marina, with a royal nod to the Queen included.
Maud was 42nd in line to the throne when she was born but is now 53rd, after the arrival of the second Sussex baby.
She has been able to join with royal relatives at several big family occasions.

She has been a bridesmaid for two royal brides – first Princess Eugenie when she married Jack Brooksbank in October 2018, and then for Lady Gabriella Windsor when she married Thomas Kingston in May 2019.
Both weddings took place at St George's Chapel in Windsor Castle, which is also where Prince Harry and Meghan Markle got married.
Lady Frederick told Hello!: "Maud loved being a bridesmaid and Eugenie is a wonderful godmother to her."
She's also been to Buckingham Palace for Christmas lunch, a tradition the Queen holds every year possible. In 2020 it could not go ahead because of the coronavirus pandemic.
The Queen is Maud's cousin twice removed.
Princess Eugenie is her fourth cousin, as they are both descendants of King George V. Eugenie is also her godmother.
Lady Gabriella is Maud's aunt.

Maud goes to school with Prince George and Princess Charlotte, as all three attend Thomas's in Battersea.
She has a younger sister Isabella who was born on 16 January, 2016. Isabella was born in Chelsea and Westminster Hospital so doesn't share the US link with her sister.
Winkleman, formally known as Lady Frederick, played Zoey in the TV show Two And A Half Men between 2011 and 2015.
Lord Frederick was working as financial analyst at the time, but was previously a music journalist.
The couple married in 2009 at Hampton Court.
Although they don't carry out royal duties, the Windsors are able to take on royal patronages for charities, and Lady Frederick said she hoped the attitude of charitable giving would pass on to her children.
She told Hello: "I hope it’s happening fairly organically without me having to deliver earnest monologues to them, because we organise a six-weekly drop-off of toys, books and clothes from a big group of nice London mothers.
"They bring things they don’t need any more to my home and we organise truck deliveries to local children in very difficult circumstances. People are incredibly generous.
"My girls just sort of add to the massive pile in the hall and living room. So I hope it’s sinking into them fairly authentically, but who knows?"
Echoing how many parents probably felt during the lockdowns in the UK, Lady Frederick said of homeschooling Maud: "The teachers have been really brilliant, but I've been loath to stick my six-year-old in front of a screen all day long. She hasn't done a lot of the lessons, so she's probably a bit behind. I'm not doing brilliantly, that's for sure."
Though Maud has roots in Tinseltown, home is now Chelsea, in London.
