THE Duke and Duchess of Sussex are celebrating the arrival of their baby daughter, who they have named Lilibet “Lili” Diana Mountbatten-Windsor.

Meghan gave birth to her second child on Friday, June 4, at 11.40am at Santa Barbara Cottage Hospital in Santa Barbara.

Lilibet, named after the Queen and her grandmother, Princess Diana, is now “settling in at home”, Harry and Meghan said.

The 7lb 11oz baby is the couple’s second child, after Archie Harrison Mountbatten-Windsor, who is aged two.

In a message of thanks from Meghan and Harry on the Archewell website they said: “On June 4, we were blessed with the arrival of our daughter, Lili.

“She is more than we could have ever imagined, and we remain grateful for the love and prayers we’ve felt from across the globe. Thank you for your continued kindness and support during this very special time for our family.”

Harry and Meghan’s press secretary added: “The Duke and Duchess thank you for your warm wishes and prayers as they enjoy this special time as a family.”

Lilibet – the Queen’s family nickname – was first used when Princess Elizabeth was just a toddler and unable to pronounce her own name properly.

Her grandfather King George V would affectionately call her “Lilibet” imitating her own attempts to say Elizabeth.

The sweet nickname stuck and she became Lilibet to her family from then on. The Duke of Edinburgh also referred to his wife as Lilibet, writing to his mother in law after their wedding: “Lilibet is the only ‘thing’ in the world which is absolutely real to me.”

Harry and Meghan’s new baby daughter – the Queen’s 11th great-grandchild – will be known as Lili.

A variation on Lily, the flower is often seen to symbolise purity, commitment, rebirth and fertility. Lili’s middle name Diana honours Harry’s later mother Diana, Princess of Wales.

It is no surprise the couple chose to pay tribute to Diana, who died in a car crash in 1997 when Harry was just 12.

Lili has been born almost a month before the princess would have celebrated her 60th birthday on July 1.

Lili’s cousin Princess Charlotte also has Diana as one of her middle names, as well as Elizabeth.

She is Charlotte Elizabeth Diana. The Duke and Duchess of Sussex’s new baby daughter Lili is eighth in line to the throne.

 The first seven places remain unchanged – the Prince of Wales, the Duke of Cambridge, Prince George, Princess Charlotte, Prince Louis, Harry, and Archie Mountbatten-Windsor.

Harry retained his place in the line of succession despite quitting royal life, and dropping his HRH style.
