The royal princesses’ names explained
Sienna’s first name is derived from the Tuscan city of Siena, and it is a clear reference to her father’s Italian roots. The baby’s middle name pays honour to the Queen.
This is Queen Elizabeth’s 12th great-grandchild and arrives just over three months after Lilibet Diana, Harry and Meghan’s second child who they also named in honour of the Queen.
Back in June, the Duke and Duchess of Sussex welcomed their daughter, Lilibet Diana Mountbatten-Windsor.
She was named after the Queen’s family nickname and also Harry’s mother Princess Diana, who died in a car crash in 1997.
Prince William and Kate Middleton’s six-year-old daughter Charlotte’s name also pays tribute to the monarch.
Her full name, including her title, is Princess Charlotte Elizabeth Diana of Cambridge.
While Charlotte’s first name is a nod to her grandfather, Prince Charles, her middle names, Elizabeth and Diana, pay homage to the same women who are Lilibet’s namesakes.
