Zara Tindall's rarely seen sister who grew up on Princess Anne's estate

Zara Tindall, daughter of Princess Anne, is a well-known figure in the public eye. However, many may not know that she has a secret half-sister.

Zara and her brother Peter Phillips are the offspring of Princess Anne, who is currently hospitalised following an 'incident' believed to involve a horse, resulting in concussion, and her first husband, Captain Mark Phillips.

The pair were married from 1973 until their divorce in 1992. Following their split, Mark found love again with Hawaiian equestrian Sandy Pflueger.

The couple had one child together, Stephanie Phillips - Zara and Peter's half-sister - before parting ways on May 3, 2012.

Despite her royal connections, Stephanie has maintained a low profile. She was educated at the esteemed Dean Close School in Cheltenham, before pursuing a degree in business management at the University of Worcester, reports the Mirror.

To support herself through university, Stephanie worked as a barmaid in a local pub, according to the Express.

Stephanie grew up at Aston Farm on the Gatcombe Estate, where Princess Anne's recent accident occurred. This location kept her close to her royal half-siblings, as Anne's ex-husband continued to reside there following their divorce in 1992.

Stephanie is a keen equestrian, a passion she shares with her sibling. This love for horses is hardly surprising given their father Mark's Olympic gold medal-winning history in horse riding for Great Britain and their mother Sandy's participation in the US Olympic dressage team at the 1984 Olympic games in Los Angeles.

Sandy has remained active in the equestrian world, serving as a dressage and eventing jury member at various competitions, including the 2016 Olympic games.

Stephanie herself is an accomplished rider, having competed at events such as the Barbury International, Wellington International Horse Trials and the West Wiltshire trials. She also enjoys travelling, sharing photos from her trips to destinations like Hawaii, Australia, New Zealand, Croatia and Slovenia on social media.

The bond between Stephanie and her royal relatives is evident. She served as a flower girl at Zara's wedding to Mike Tindall in 2011 and Peter's wedding to Autumn Kelly in 2008.

In a sweet gesture, she asked Peter's daughters Savannah, 11, and Isla, 10, and Zara's daughters Mia, eight, and Lena, four, to be her flower girls at her own wedding in 2022. Princess Anne was also present to witness the special occasion.

The Worcester-based eventing professional previously referred to Peter as 'the best big brother out there' in an Instagram post, and she is often spotted with them at eventing competitions - in one amusing photo, she was seen giving her brother-in-law Mike Tindall a piggyback.

Stephanie exchanged vows with William Hosier in July 2022 at St Mary The Virgin Church in Tetbury, Gloucestershire. The couple shared their engagement news in September 2021, after he popped the question with a sapphire and diamond oval ring.
