Of all the Royal Family, it it Princess Anne’s branch that is perhaps the most low key, with the Queen’s only daughter raising her children, Peter Phillips and Zara Tindall, away from the spotlight, with no royal titles. So in many ways it is unsurprising that the two royal siblings have a third – rarely talked about – half-sister.
23-year-old Stephanie Phillips is the daughter of Peter and Zara’s father Captain Mark Phillips, Princess Anne’s first husband, who she divorced in 1992. Her mother is Hawaiian equestrian Sandy Pflueger, who, like Princess Anne, competed in the Olympics, as part of the 1984 US dressage team. She is the couple’s only child – they separated in 2012.
Born on 2 October 1997, Stephanie grew up at Aston Farm on the Gatcombe Park estate, just a stone’s throw from her elder half-siblings, as well as her father’s first wife, Princess Anne. She became as horse-mad as the rest of the family, and now competes in equestrian events, from Wellington International Horse Trials to the West Wiltshire trials, and is even sponsored by the saddle-maker Voltaire Design.
Unsurprisingly considering how amicable her father is with his ex-wife, Stephanie is close to her siblings, despite the large age gap, and was a flower girl at both of their weddings. She often posts photos with Zara and Mike Tindall and Peter and his now ex-wife Autumn, on her Instagram account, too, including some in fancy dress. She’s also been seen at various sporting engagements with her siblings, and called Peter ‘the best big brother’ in a sweet social media snap.
