During The Duke and Duchess of Sussex's first official interview together, Prince Harry and Meghan Markle openly discussed their desire to have children "in the near future".
'This goes back to King George I, and the law's never been changed.
Noticeably absent from the morning mass were the couple's children, Prince George, five, Princess Charlotte, three, and four-month-old Prince Louis. "He did it because he had a very poor relationship with his son, the future King George II, so they had this law passed that meant the King was the guardian of his grandchildren".
The prince is the third in line of succession to the British throne, behind his grandfather Prince Charles and father, Prince William.
It's not a dormant right as well.
"Technically, they needed permission for travel".
Prince Charles, the Wessexes (without James), and Princess Anne and her family were all photographed arriving at the church in separate cars.
Her simplistic and elegant outfit evoked memories of Princess Diana who also wore a grey coat while at Balmoral in 1981.
Perhaps frustratingly, William and Kate shouldn't expect to receive legal custody of their three children any time soon, either.
Earlier it became known that the mother of the duchess is preparing to move to London to live next to her daughter.
According to reports, the Royal Family has a odd custody tradition, with Queen Elizabeth actually having full legal custody of some of the minor royals. She attended the wedding of Prince Harry and Meghan, Trooping the Colour, RAF 100 events and Prince Louis's christening, but has largely remained out of the public eye.
"He understands they want to raise their children privately ... the only thing Charles might ask for is more picture", she quipped.
