Sarah Margaret Ferguson (born 15 October 1959), formerly Sarah, Duchess of York, and commonly known as Fergie, is a British author, spokesperson, and television personality. She is the ex-wife of Andrew Mountbatten-Windsor, the former Prince Andrew, Duke of York, who is the second son of Queen Elizabeth II and the younger brother of King Charles III.
Ferguson grew up in Dummer, Hampshire, and attended the Queen's Secretarial College. She later worked for public relations firms in London and for a publishing company. She began a relationship with Andrew in 1985, and they were married on 23 July 1986 at Westminster Abbey, upon which she became Duchess of York. They have two daughters: Beatrice and Eugenie. Their marriage, separation in 1992, and divorce in 1996 attracted extensive media coverage.
Both during and after her marriage, Ferguson has been involved with several charities, primarily focused on supporting cancer patients and children. She was the patron of the Teenage Cancer Trust from 1990 to 2025 and founded Children in Crisis and Sarah's Trust. She has written several books for children and adults, and has worked on TV and film production.
In the years following her divorce, Ferguson was the subject of various scandals that affected her relationship with the royal family. Her friendship with the American child sex offender Jeffrey Epstein led to the termination of her roles as patron and spokesperson for multiple charities. In October 2025, Ferguson ceased using the courtesy title Duchess of York following Andrew's announcement that he would no longer use his peerage titles.
Sarah Margaret Ferguson was born on 15 October 1959 at London Welbeck Hospital, London, the second daughter of Major Ronald Ferguson (1931–2003) and Susan Barrantes (née Wright; 1937–1998). She has one older full sister, Jane. After her parents divorced in 1974, her mother married polo player Héctor Barrantes the following year and moved to Trenque Lauquen in the Argentine pampas. Ferguson remained at the 480-acre (190-hectare) Dummer Down Farm in Dummer, Hampshire, which had been her father's home since she was eight. Major Ferguson married Susan Deptford in 1976, and had three more children: Andrew, Alice, and Elizabeth. Ferguson later said that, at the age of 12, when her parents' marriage began to break down, she developed an eating disorder and "turned to overeating for comfort".
Ferguson, known informally as "Fergie", once described her family as "country gentry with a bit of old money". She is a descendant of King Charles II of England through three of his illegitimate children: Charles Lennox, 1st Duke of Richmond; James Scott, 1st Duke of Monmouth; and Anne Lennard, Countess of Sussex. Her wider ancestry is aristocratic; she is the great-great-granddaughter of the 6th Duke of Buccleuch, a great-granddaughter of the 8th Viscount Powerscourt, and a descendant of the 1st Duke of Abercorn and the 4th Duke of Devonshire. She is distantly related to her former husband as both are descended from the 4th Duke of Devonshire and from King James VI and I.
Ferguson attended Daneshill preparatory school in Stratfield Turgis, Hampshire. Staff at the school described her as a "courageous, bubbly and outgoing little girl". She later attended Hurst Lodge School in Ascot. Although she did not shine academically, she showed talent in swimming and tennis. From a young age, Ferguson developed an interest in skiing and later worked briefly as a chalet girl. During her teenage years, she worked as both a cleaner and a waitress. After completing a course at Queen's Secretarial College at the age of 18, she took a job at an art gallery. She subsequently worked in two public relations firms in London, followed by a position at a publishing company. Before her marriage, Ferguson dated Kim Smith-Bingham, a stockbroker, and Paddy McNally, a motor racing manager more than 20 years her senior.
On 19 March 1986, Ferguson and Prince Andrew announced their engagement. The pair had known each other since childhood, meeting occasionally at polo matches, and were reacquainted at Royal Ascot in 1985. Before the engagement, Ferguson had accompanied Diana, Princess of Wales, during her official tour of Andrew's ship HMS Brazen. Andrew designed the engagement ring himself: ten diamonds set around a Burmese ruby, chosen to complement Ferguson's red hair. Her friendly manner and lively spirit made her a welcome addition to the royal family.
After securing the Queen's consent, which was then required under the Royal Marriages Act 1772 for all descendants of King George II, Ferguson and Andrew were married at Westminster Abbey on 23 July 1986. The Queen bestowed the title Duke of York upon Andrew, and, as his wife, Ferguson automatically gained his royal and ducal status, becoming "Her Royal Highness The Duchess of York". In her new role, she joined the Duke in undertaking royal engagements, including overseas visits.
In 1987, Ferguson and Andrew undertook a 25-day tour of Canada. In February that year, she passed her private pilot's licence after completing a 40-hour training course paid for by Lord Hanson as a wedding gift, and she was presented with her wings at RAF Benson in December.
On 22 January 1988, during a visit to New York City to attend a fundraising event, Ferguson was attacked by a young man at the entrance of her hotel. The man, who shouted "murderers 3/8" and carried an Irish Republican Army flag as he rushed towards her, was charged with "attempted assault on the Duchess and assault on a federal agent". A State Department press officer later confirmed that "she was unharmed in the incident".
In March 1988 the couple made a royal tour of California. Two British newspapers described the trip as a "brash, vulgar, excessive, weak-humored exhibition by two royals". City officials in Los Angeles defended the couple, calling the criticism "awful" and offensive, while observers described the Duke and Duchess as friendly and said they had fulfilled their duties.
The couple's first child, Princess Beatrice, was born on 8 August 1988. Ferguson experienced high blood pressure and excessive water retention during the pregnancy. In September, she joined Andrew in Australia for an official visit, a decision that drew criticism from the press for leaving her newborn daughter in the United Kingdom. Their second daughter, Princess Eugenie, was born on 23 March 1990 by caesarean section. During her marriage, the tabloid press frequently mocked Ferguson's weight – which reached 15 stone 10 pounds (100 kg) (220 lbs) during her first pregnancy – and labelled her "Duchess of Pork" and "Fat Fergie". She vowed to lose weight after Beatrice's birth. In 1989, Ferguson was credited with helping to popularise the Callanetics exercise regime in the United Kingdom after reports that founder Callan Pinckney had given her private tuition. She received praise for her weight loss, as well as some criticism for not gaining enough weight during her second pregnancy. Ferguson later said that the press coverage of her weight damaged her self‑esteem and worsened her eating disorder.
In May 1989, Ferguson undertook an official solo visit to Berlin.
Biographer Sarah Bradford wrote that Andrew's duties as a naval officer required long periods away from home. According to Ferguson, the couple saw each other for only 40 days a year during the first five years of their marriage. By 1991, the relationship was under strain, with Ferguson finding life within the royal family increasingly difficult. Her friendship with Texan multimillionaire Steve Wyatt, son of Lynn Wyatt, attracted considerable publicity when photographs – including one showing Wyatt with Ferguson's infant daughter – appeared in newspapers in January 1992. Ferguson and Andrew announced their separation on 19 March 1992. After the announcement, the palace stated that Ferguson would no longer undertake public engagements on behalf of the Queen, and the Queen later confirmed that she would not assume responsibility for Ferguson's debts. Ferguson established a separate residence from Andrew in 1992, moving to Romenda Lodge on the Wentworth Estate in Surrey.
