Daisy Knatchbull, Prince William and Prince Harry’s Cousin, Gets Engaged With 'Turtle Ring'

Daisy Knatchbull, Prince William and Prince Harry’s cousin, announced her engagement to Italian music executive Giovanni Damiani.

“Getting hitched (and making gift shop turtle rings a thing),” Daisy wrote via Instagram on April 13. The first photo showed the couple making excited faces while vacationing in the Bahamas. A dainty gold turtle ring could be seen on Daisy’s left hand. In other videos from the special moment, her future husband wrote, “Will you marry me?” in the sand using seaweed.

The comments were filled with British celebrities, including actress Sophie Turner and Nigella Lawson, as well as royals, like Princess Olympia of Greece and Princess Beatrice‘s husband, Edoardo Mapelli Mozzi, who wrote, “Yipeeeeee. Congratulations.”

Daisy is the third cousin of Prince William, 43, and Prince Harry, 41. Her parents are Philip Knatchbull and Atalanta Cowan, and she is the great-granddaughter of Louis Mountbatten, the 1st Earl Mountbatten of Burma and uncle of Prince Philip, Duke of Edinburgh. 

Her last name has been circulating lately. She is the niece of Penelope “Penny” Knatchbull, Countess Mountbatten of Burma, who was known as a close confidant of Prince Philip later in his life. She was included as a character in Season 5 of The Crown, portrayed by Natascha McElhone, and she has even been referred to as the “second-most important woman in the Duke of Edinburgh’s life” in the 2020 biography, Prince Philip Revealed.

While her family is adjacent to the royals, Daisy has been forging her own path. She is the founder and CEO of her design brand, Knatchbull, which was “Savile Row’s first and only shopfront exclusively for women in its prestigious 200-year history,” per the brand’s website. 

“Through her all-female staffed business, Daisy continues to challenge industry norms while maintaining the street’s reputation for exceptional craftsmanship, combining centuries-old techniques with modern styling specifically designed for women,” Knatchbull’s website reads.

Kate Middleton is famously a fan of Knatchbull’s designs. The Princess of Wales wore a white ruffled blouse from the brand on at least three occasions in 2025, including to present the Queen Elizabeth II Award for British Design in May, the Women’s Rugby World Cup in September, and the Future Workforce Summit in London in November.

Daisy is making sure women all over the U.K. are dressed as impeccably as her royal family. 

“I would love to give as many women as possible the experience to have something made bespoke,” she told Quintessentially in 2023. “Our clients always say they wish they’d found us sooner; our biggest problem [as a brand] is that people don’t know we exist.”
