Princess Eugenie has revealed she has named her baby daughter Adelaide Elizabeth Annina Brooksbank.

Eugenie and husband Jack Brooksbank welcomed their third child two weeks ago.

On Monday the couple revealed that she is to be called Adelaide Elizabeth Annina Brooksbank in tribute to “three people we love and admire past and present”, including Adelaide’s late great-grandmother Queen Elizabeth II, and to reflect both English and Portuguese history – “two places we love and call home”.

The latest addition to the royal family was born on August 3 in Lisbon, Portugal, weighing 6lb 9oz.

The name Adelaide is understood to have been inspired by Queen Adelaide (1792-1849), who was married to King William IV, as well as Maria Adelaide of Portugal.

Annina was inspired by a personal connection to Eugenie and Jack, which has not been revealed.

Adelaide’s birth was a rare occasion where a member of the British royal family has been born overseas, with Eugenie and her husband having a home and other connections in Portugal.

She is a younger sibling to the couple’s two sons August, five, and Ernest, three, known as Augie and Ernie.

Eugenie, writing on Instagram about her third child, said: “Two weeks ago today we welcomed our girl to the world. And since then we’ve had the most special, cosy and love-filled time.

“We are so happy to share Adelaide Elizabeth Annina Brooksbank.

“Named after three people we love and admire past and present, including her great-grandmother who we hold close in our hearts. Her name is part of English and Portuguese history, two places we love and call home.

“Augie and Ernie are already the best big brothers.”
