Princess Eugenie and Jack Brooksbank Welcome Daughter Adelaide Elizabeth Annina in Lisbon

Middle names Adelaide and Annina are believed to reference relatives on Jack Brooksbank's side of the family, a connection highlighted by Town & Country noting that 'either Adelaide or Annina references a relative on Jack’s side of the family.'
The official birth details specify the exact time and location: Adelaide Elizabeth Annina Brooksbank was born at 6:20 p.m. on Monday, August 3, 2026, at a hospital in Lisbon, Portugal.
Buckingham Palace confirmed the birth with a statement noting that the King was delighted by the arrival of Eugenie and Jack's daughter.
Hello! Magazine highlights the broader royal pattern of name announcements, citing Beatrice and Edoardo Mapelli Mozzi's decision to wait 13 days to reveal Sienna's name in 2021 and other royals who have varied intervals, illustrating that Eugenie and Jack's approach fits a wider tradition of taking time to choose a name.
Princess Eugenie and Jack Brooksbank have welcomed a baby daughter, Adelaide Elizabeth Annina Brooksbank, born on August 3, 2026, at 6:20 p.m. at a hospital in Lisbon, Portugal. The baby weighed 6 pounds 9 ounces and is the couple's first daughter and third child. Buckingham Palace confirmed the birth, noting that King Charles was "delighted" by the arrival.
Eugenie shared the name on Instagram roughly two weeks after the birth. She described it as a tribute to "three people we love and admire," including her late great-grandmother Queen Elizabeth II. Adelaide is now fifteenth in line to the throne, according to Parade.
The name Adelaide Elizabeth Annina carries deep meaning for both parents. Elizabeth is a clear nod to the late Queen Elizabeth II, Eugenie's great-grandmother. Parade reported that Eugenie said the name honors three people the couple "love and admire past and present."
The names Adelaide and Annina are also believed to reflect Jack Brooksbank's family roots. Town & Country noted that "either Adelaide or Annina references a relative on Jack's side of the family." Eugenie described the full name as part of "English and Portuguese history," nodding to the family's ties to Lisbon, where the baby was born.
Adelaide joins older brothers August Philip Hawke Brooksbank, born in 2021, and Ernest George Ronnie Brooksbank, born in 2023. Eugenie's Instagram post included photos of Adelaide alongside her brothers, who the family calls Augie and Ernie. Eugenie highlighted their new roles as big brothers in her announcement.
Perth Now reported that the family is already adjusting to life with three children. The warm sibling introduction echoed Eugenie's previous birth announcements, which have always centered on family closeness and personal meaning.
Eugenie and Jack waited about two weeks before revealing Adelaide's name. This is not unusual among royals. Hello! Magazine pointed out that Princess Beatrice and her husband Edoardo Mapelli Mozzi waited 13 days before announcing their daughter Sienna's name in 2021. Other royals have also varied the timing of name reveals.
Eugenie followed the same pattern with her sons. The couple took their time with both August and Ernest before going public with names. Lismore City News noted that choosing a name in tribute to loved ones appears to be a deliberate and personal process for the couple.
With her birth, Adelaide enters the British line of succession at fifteenth place. She is a granddaughter of Prince Andrew and Sarah Ferguson, and a first cousin of Prince William and Prince Harry. Parade noted her position in the succession, though as a child born further down the line, she holds no official royal duties.
Eugenie and Jack have lived in Lisbon for several years. The choice to give birth there reflects the family's strong connection to Portugal. The baby's name, which Eugenie called part of "English and Portuguese history," cements that dual identity from the very start, according to Head Topics.
