Lady Henrietta Stanley, 29, known as Hetty, married Alexander 'Sasha' Reviakin on July 4 at Knowsley Hall, the ancestral seat of her family in Merseyside. The ceremony was the first family wedding to be held at the stately home in 160 years, according to the Countess of Derby.

The bride wore an embroidered, strapless white gown by Suzanne Neville, a diamond necklace, and the Derby Tiara from 1890. Her husband, also 29, is a descendant of newspaper magnate William Berry, the 1st Viscount Camrose, and is the only son of Russian art collector Sergei Reviakin and artist Rosanna Gardner. Lady Henrietta and Sasha Reviakin first met in 2024 at the National Portrait Gallery in London.

'A momentous occasion yesterday to see our daughter Hetty marry Sasha - 4th of July 2026 - the first family wedding to be held [at Knowsley Hall] for 160 years,' the mother of the bride shared on Instagram. She added, 'It was truly a wonderful day surrounded by friends and family.'

The Countess of Derby wore a blush pink floral dress with matching heels and a Philip Treacy hat. Bridal makeup artist Josh McVeigh, who also did the Countess's makeup, described the event as 'the wedding of a lifetime' and a career highlight.

The wedding festivities included the bride changing outfits for the reception, where she and Sasha Reviakin were seen dancing. Videos of the celebration were shared by the Countess of Derby.

Wedding preparations are also underway for the couple's elder son, Lord Edward Stanley, 28. He is engaged to Victoria Jooris, 26, a Belgian noblewoman and associate at investment firm Bridgepoint. The Earl of Derby confirmed the engagement, stating, 'We could not be more thrilled by Ed and Victoria's engagement.' Lord Edward Stanley, who was a page of honour to the late Queen Elizabeth II, is set to inherit Knowsley Hall.

Lord Edward Stanley and Victoria Jooris, who studied at Oxford University, plan to exchange vows next year at Knowsley Hall.
