Olivia Grosvenor, Duchess of Westminster

Olivia Grosvenor, Duchess of Westminster (née Henson; born 1 September 1992), is a British aristocrat. Upon her marriage to the 7th Duke of Westminster in June 2024, she became the tenth Duchess of Westminster.

Early life and family Olivia Grace Henson was born on 1 September 1992 in London to Rupert Cornelius Brooke Henson, a banker, and Caroline Belinda Frisby, a descendant of London banker Henry Hoare III and Sir Richard Hoare, founder of the bank C. Hoare & Co.

Her maternal great-great-grandmother was Lady Geraldine Mariana Hoare (née Hervey; 1869–1955), the daughter of Lord Augustus Hervey, the sister of the 4th Marquess of Bristol and a great-granddaughter of the 5th Duke of Rutland.

Henson's great-granduncle Henry Peregrine Hoare's (1901–1981) first wife, Anne, Lady Ebury, was the mother of Francis Grosvenor, 8th Earl of Wilton, the heir presumptive to Henson's husband's subsidiary title, Marquess of Westminster.

Education and career Henson attended Dragon School, a private school in Oxford, before attending Marlborough College, a boarding school in Wiltshire, alongside Princess Eugenie. She graduated from Trinity College, Dublin (TCD), with a degree in Hispanic Studies and Italian.

Henson works in the sustainable food and drinks industry.

Marriage and issue In April 2023, Henson's engagement to the 7th Duke of Westminster was announced. The duke had proposed on the Eaton Estate, his family estate, after nearly two years of being in a relationship with Henson. The Duke is close to the British royal family; he is the godson of King Charles III and godfather to Prince George of Wales and Prince Archie of Sussex. Henson wore the 1906 Grosvenor Myrtle Leaf diamond tiara by Fabergé for the ceremony. The embroidery design on her bridal gown incorporated floral motifs and edgings from the circa 1880 veil worn by her great-great-grandmother Lady Geraldine Mariana Hervey upon her marriage in 1898.

The Prince of Wales served as an usher during their wedding. As the couple left the cathedral heading towards an awaiting car, disruption was caused by two members of Just Stop Oil.

On 27 July 2025, she gave birth to a daughter, Lady Cosima Florence Grosvenor.
