Prince Harry and William’s close friend has announced the birth of his first child. Hugh Grosvenor and Olivia Henson, Duke and Duchess of Westminster, have welcomed a baby girl.

They have revealed that their baby girl is named Cosima Florence Grosvenor. A statement released today read: “The Duke and Duchess of Westminster are thrilled to announce the birth of their baby daughter.”

The statement continued: “They have named her Cosima Florence Grosvenor, who was born in London today, 27 July.

“Both the Duchess and Cosima are doing well. The Duke and Duchess now look forward to spending this special time together as a family.”

Although a rather unusual name for a member of the Royal Family, Cosima is of Greek and Italian origin.

The name carries a beautiful, elegant meaning and is derived from the Greek word kosmos (κόσμος), which means order, harmony, or the universe.

The couple, who met in 2021 and wed last summer, announced the joyous news that they were expecting their first child back in March.

At the time, a spokesperson for the couple said: “The Duke and Duchess of Westminster are very pleased to share that the Duchess is expecting a baby in the summer.

“The couple are delighted with the news and are very much looking forward to starting a family together.”

Sharing a close bond with Prince Wiliam and Prince Harry, the Duke of Westminster holds the title of godfather to both William’s eldest son, 12-year-old Prince George and Harry’s only son, six-year-old Prince Archie.
