Prince Harry and Meghan Markle this week announced the birth of their daughter, Lilibet 'Lili' Diana Mountbatten-Windsor.

The name Lilibet has been chosen in honour of the baby's great-grandmother, Queen Elizabeth II, a family nickname the monarch has had since childhood; while Diana is a touching nod to Prince Harry's late mother, Princess Diana.

While she may be the first royal tot to receive the unique nickname as a moniker, Lilibet is not the first, and likely won't be the last, to be named after the Queen.

In fact, British royals have a long tradition of keeping names in the family. Here, we explore which members of the royal family have been named after Queen Elizabeth II and Prince Philip.

Royals named after Queen Elizabeth II 

Queen Elizabeth II was born Princess Elizabeth Alexandra Mary Windsor, to the Duke of York, Albert Frederick Arthur George, and her mother, Elizabeth Angela Marguerite Bowes-Lyon, who went on to become King George VI and Queen Elizabeth.

The Queen herself was named after her mother, and it's a name that has since been passed down through royal generations.

Lilibet's name has drawn the most comparisons with Prince William's daughter, Princess Charlotte Elizabeth Diana, 6. Much like Lilibet, or Lili, the daughter of the Duke and Duchess of Cambridge was named after her paternal great-grandmother and grandmother.

The Queen named her only daughter Princess Anne Elizabeth Alice Louise. Princess Anne, 70, passed the name down to her daughter, born Zara Anne Elizabeth Phillips. Phillips, however, is not to be confused with Prince Philip's name; it is the surname of the Princess Royal's first husband, Mark Phillips.

Zara, now Zara Tindall, 40, has two daughters of her own and her second-born was named Lena Elizabeth Tindall, 2, in honour of her great-grandmother. Her brother, Peter Phillips, 43, and ex-wife Autumn Phillips named their second daughter Isla Elizabeth, 9.

Like his sister, Princess Anne, Prince Andrew, 61, named his eldest daughter after his mother, calling her Princess Beatrice Elizabeth Mary. Princess Beatrice, 32, is currently pregnant with her first child with husband Edoardo Mapelli Mozzi.

In keeping with tradition, Prince Edward, 57, the youngest son of the Queen and Prince Philip, is father to Lady Louise Alice Elizabeth Mary, 17.

Royals named after Prince Philip 

It is not just female royals who have been given the honorific treatment, however, with many male royals honouring Prince Philip with the names of their children.

Prince Charles Philip Arthur George, the Queen and Prince Philip's eldest child, was named after his father, and also his maternal grandfather, King George VI.

In turn, Prince Charles, 72, passed the name down to his eldest son, Prince William Arthur Philip, 38. However, the Duke and Duchess of Cambridge did not continue the tradition with their sons, naming them Prince George Alexander Louis, 7, and Prince Louis Arthur Charles, 3.

Prince Edward and Sophie, Countess of Wessex named their son James Alexander Philip Theo, now aged 13 and known as James, Viscount Severn.

The name Philip has been passed down to the generation of great-grandchildren in 2021, with the birth of Princess Eugenie, 31, and Jack Brooksbank's baby boy, August Philip Hawke Brooksbank, on February 9, and Zara and Mike Tindall's son, Lucas Philip Tindall, born on March 21.
