Princess Eugenie confirms daughter's name: Adelaide Elizabeth Annina Brooksbank
Princess Eugenie and Jack Brooksbank have confirmed their newborn daughter's name: Adelaide Elizabeth Annina Brooksbank, revealed on 17 August 2026 — two weeks after the baby's birth at a hospital in Lisbon, Portugal on 3 August at 6.20am. The official announcement of the birth was published on the royal.uk website on 4 August, and Eugenie shared the news on her Instagram account @princesseugenie the same day, captioning her post with "Baby Girl Brooksbank" and garnering roughly 346,000 likes and 7,427 comments Royal Family. The name was confirmed by Hello! magazine on 17 August Hello!.
Adelaide is the third child of Princess Eugenie and Jack Brooksbank, joining older brothers August (age five) and Ernest (age three). August's full name is August Philip Hawke Brooksbank, revealed 11 days after his birth in 2021. Ernest's full name is Ernest George Ronnie Brooksbank, honouring his great-great-great-grandfather George, his Grandpa George, and his Grandpa Ronald. The couple had announced the pregnancy earlier in 2026 with a photo of their sons holding a baby scan, captioned "Baby Brooksbank due 2026!" BBC News.
Eugenie and Jack chose to wait two weeks to pick what they felt was the perfect name for their daughter. This is a family pattern: in 1988, the Duke and Duchess of York took two weeks to confirm Princess Beatrice's name. The late Queen Elizabeth II did not share Prince Charles's name publicly for a month after his birth in 1948.
Eugenie's elder sister Princess Beatrice has followed the same custom. She and her husband Edoardo Mapelli Mozzi waited 13 days to reveal daughter Sienna's name in 2021, and a week to announce the birth of baby Athena and her name the following year. Both of Beatrice's daughters carry the middle name Elizabeth — Sienna Elizabeth (age four) and Athena Elizabeth Rose (age one) — honouring the late Queen Elizabeth II.
For royal watchers, the two-week wait is part of the ritual rather than a surprise. But the name Adelaide carries its own weight of resonance: the middle name Elizabeth echoes the pattern Beatrice set for her own daughters, linking both York sisters' children to their late grandmother. Annina remains a more private choice, its significance not yet explained publicly.
The birth took place in Lisbon, where Eugenie and Brooksbank have been based Hola. The official Royal Family Facebook page carried the household's announcement, describing Princess Eugenie and Mr Jack Brooksbank as "delighted" British Monarchy Facebook. Adelaide, as the daughter of a princess, holds no royal title — under the 1917 Letters Patent, the formal instrument by which a monarch sets out who may use the style HRH and Prince or Princess, those titles pass through the male line to the grandchildren of a sovereign, not to great-grandchildren.
For now, Adelaide Elizabeth Annina Brooksbank is the newest entry on a family tree that spans palaces and Portuguese hospitals, named with a care that took a fortnight to settle.
