Adelaide Elizabeth Annina Brooksbank

Eugenie and Brooksbank welcomed their third child on Aug. 3 in Lisbon, Portugal. Two weeks later, the couple shared the baby’s name with the public: Adelaide Elizabeth Annina Brooksbank.

Eugenie explained the meaning behind the moniker on Instagram, writing that Adelaide’s first middle name, Elizabeth, is a tribute to the late Queen, “who we hold close in our hearts.”

“Her name is part of English and Portuguese history, two places we love and call home,” she added.

August Philip Hawke Brooksbank

Adelaide’s older brother August, who was born in February 2021, is named after not one but several members of the royal family.

August’s first name honors Queen Victoria’s husband Prince Albert, who was born Franz Albert August Karl Emanuel. His first middle name, Philip, is a tribute to the late monarch’s husband, Prince Philip, who died in April 2021 at the age of 99. Finally, his second middle name, Hawke, comes from a 5x grandfather on his dad’s side, Rev. Edward Hawke Brooksbank.

Prince George Alexander Louis

Born in July 2013, Prince William and Kate Middleton’s older son, George, was named after his great-grandmother’s father, King George VI.

The future king’s second name, Alexander, is a reference to the Queen’s middle name, Alexandra. His third name, which he shares with both his father William and his brother, Prince Louis, is a tribute to the late Lord Louis Mountbatten.

Princess Charlotte Elizabeth Diana

George’s sister Charlotte was born two years later, in May 2015. The princess’s first name is the female version of Charles, and thus honors her grandfather King Charles.

The rest of her name, meanwhile, references two late royals. Her second name, Elizabeth, pays tribute to the late monarch, while her third name was chosen in homage to her late grandmother, Diana.

Prince Louis Arthur Charles

Louis was born in April 2018 and was also given a name full of tributes to his relatives.

His first name comes from the late Lord Louis Mountbatten, while his second name, Arthur, is a nod to the legendary King Arthur of sixth-century England. Finally, his third name, Charles, honors his grandfather, the King.

Princess Lilibet Diana

Prince Harry and Meghan Markle chose to break tradition with their son Prince Archie’s name, which does not harken back to any late members of the royal family. When his sister Lilibet was born in June 2021, however, the couple opted to honor not one but two royals.

Lilibet’s first name is a nod to the Queen’s childhood nickname. Her middle name honors her late grandmother, Diana. She also shares the latter name with her cousin, Charlotte, whose third name is Diana.

Sienna Elizabeth Mapelli Mozzi

Princess Beatrice and Edoardo Mapelli Mozzi welcomed two daughters after tying the knot in 2020.

Sienna Elizabeth Mapelli Mozzi was born in September 2021 and bears her late great-grandmother’s name, Elizabeth.

Athena Elizabeth Rose Mapelli Mozzi

Sienna’s sister, Athena Elizabeth Rose Mapelli Mozzi, was born in January 2025.

Beatrice and Edo linked their daughters’ names by also giving her the late Queen’s moniker, Elizabeth, as her first middle name.

Lady Louise

Prince Edward and Sophie, Duchess of Edinburgh welcomed their daughter, Lady Louise Alice Elizabeth Mary Mountbatten-Windsor, in November 2003.

Two of her middle names, Alice and Elizabeth, reference other royals. Alice was the name of Philip’s mother, Princess Alice of Greece and Denmark. Elizabeth, was, of course, the name of Philip’s wife, the Queen.

James, Earl of Wessex

Louisei ’s brother, James, joined the family in December 2007. His full name is James Alexander Philip Theo Mountbatten-Windsor, Earl of Wessex.

As with his cousin August, James’ second middle name pays homage to his late grandfather, Philip.
