Princess Eugenie Reveals Daughter's Name: Adelaide Elizabeth Annina Brooksbank
Princess Eugenie has revealed the name of her newborn daughter: Adelaide Elizabeth Annina Brooksbank. The announcement came via her Instagram account on 17 August 2026, with British Vogue carrying the exclusive reveal of the full name (Royal Central; British Vogue).
Adelaide was born in Lisbon on 3 August 2026. She is the third child of Princess Eugenie and Jack Brooksbank, and their first daughter. Her big brothers are August, known as Augie, aged five, and Ernest, known as Ernie, aged three.
Each of Adelaide's three names honours someone or something meaningful to her parents. The middle name Elizabeth was chosen for Queen Elizabeth II, Eugenie's grandmother, who died in September 2022. Eugenie said the full name reflected both Portuguese and English history, a nod to the city of her birth and the family tree on both sides. The name Adelaide itself carries royal pedigree on the British side: Queen Adelaide was consort to King William IV in the 1830s, and the Australian city of Adelaide was named for her. Annina, the third name, was not separately explained in the announcement.
Adelaide is fifteenth in line to the British throne. As a descendant of a sovereign's granddaughter rather than a sovereign's child, she holds no royal title — the style HRH and princely status were restricted, by letters patent of George V in 1917, to the monarch's children and grandchildren in the male line, with specific exceptions. She is also the fifteenth great-grandchild of Queen Elizabeth II and Prince Philip.
Princess Eugenie, 36, is the younger daughter of the Duke of York and Sarah, Duchess of York. She married Jack Brooksbank in October 2018 at St George's Chapel, Windsor. The family relocated to Portugal in recent years, with Brooksbank's work in the drinks and hospitality trade cited as a factor; Adelaide's birth in Lisbon reflects that base.
The tradition of waiting before naming a royal baby is a long one. Royal parents have typically taken several days to announce a name, allowing for family consultation and, historically, the monarch's awareness. Eugenie, as a granddaughter rather than child of the reigning sovereign, is not bound by the tighter protocols that govern the households of working royals — she does not carry out official engagements on the monarch's behalf and is not funded by the Sovereign Grant, the annual payment from Crown Estate profits that supports the King's official duties. Her Instagram announcement, rather than a formal palace statement, fits that more personal register.
For royal watchers, the name Adelaide adds another thread linking the current generation to the British and now Portuguese chapters of the family's story. A first daughter after two sons, born in a city the family now calls home, named for a queen grandmother and a queen consort from two centuries back — the paperwork may be informal, but the lineage in those three names runs deep.
