The Duke of Westminster has marked a huge family milestone this week.
Hugh Grosvenor, 35, who is godfather to both Prince George and Prince Archie, celebrated his daughter’s first birthday this week.
The aristocrat and his wife, the Duchess of Westminster, welcomed their first baby, a girl named Lady Cosima Florence Grosvenor, on July 27, 2025.
A statement said at the time: “The Duke and Duchess of Westminster are thrilled to announce the birth of their baby daughter.
Both the duchess and Cosima are doing well.
The duke and duchess now look forward to spending this special time together as a family.”

The couple, who live in Cheshire, would have undoubtedly marked the sweet occasion with a private family celebration.
Earlier this month, on July 14, new parents Hugh and Olivia were pictured in London at an event alongside the Mayor of London, marking the reopening of Grosvenor Square ahead of its public opening on July 20.
The Westminster Foundation partnered up with London Wildlife Trust to deliver a climate change and biodiversity education programme from the new Education Centre at the heart of the Square.
It has given a £500,000 grant to support opportunities for children, young people and families to “connect with nature through hands-on learning experiences focused on biodiversity, climate change and the natural environment”.
Hugh is one of the UK’s biggest landowners and a close friend of both the Prince of Wales and the Duke of Sussex.
Prince William acted as an usher at his wedding at Chester Cathedral in 2023, but Harry agreed with the groom that he would not attend amid their long-running rift.
Princess Eugenie attended the wedding too.
The duke, once considered one of the country’s most eligible bachelors, became an instant billionaire when he inherited his title and control of the historic Grosvenor Estate aged 25, following the death of his father from a heart attack in 2016.
His property company, Grosvenor Group, owns hundreds of acres of land in Mayfair and Belgravia, as well as major city centre developments such as Liverpool’s One shopping centre.
In 2020, the duke donated £12.5 million to the UK’s Covid-19 relief effort, including funds for NHS Charities Together and for medical research and development.
