Princess Eugenie gave birth to a daughter on 3 August 2026, delivered at a hospital in Lisbon — making the newborn the first member of the House of Windsor to be born in Portugal. The baby girl weighed 6 pounds and 9 ounces and is a younger sister to Eugenie's sons August, 5, and Ernest, 3. Her name has not yet been announced. Royal Central

The first photograph of the baby was taken by her father, Jack Brooksbank. The couple have lived in Portugal for parts of the year for some time because of his work commitments. Both of their sons were born in London — August at the Portland Hospital on 9 February 2021 — but their daughter was delivered in the Portuguese capital.

Buckingham Palace had confirmed several months earlier that Eugenie, 36, was expecting her third child. Eugenie first shared the news herself on Instagram on 4 May 2026 with a post reading "Baby Brooksbank due 2026!" Reuters The couple's formal announcement — "Princess Eugenie and Mr Jack Brooksbank are very pleased to announce that they are expecting their third child together, due this summer" — followed.

The King has been informed of the arrival of his great-niece. In a statement on social media, the Royal Family said: "Their Majesties The King and Queen… were delighted to be informed of the news."

The newborn is fifteenth in line to the British throne. She follows her mother and both brothers in the succession and sits ahead of Princess Anne and Prince Edward — a reflection of the rules governing who can inherit the crown, where a person's place is fixed by descent and birth order rather than by royal title or public role.

Her birth will be registered in Portugal, not in the United Kingdom. That registration will not automatically entitle her to Portuguese citizenship; under Portuguese law, citizenship depends on whether her parents meet detailed residency requirements.

What makes this arrival unusual is the paperwork. A Windsor born on foreign soil, registered in a Portuguese civil registry, and fifteenth in line to a British throne she will almost certainly never occupy — the newest royal baby sits at the point where family life meets constitutional record-keeping, and the two make awkward companions.

Eugenie, the younger daughter of the Duke of York and Sarah, Duchess of York, married Brooksbank at St George's Chapel, Windsor, in October 2018. Their sons' names, August and Ernest, both belong to the family of Prince Albert, Queen Victoria's husband and first cousin. Whether the new daughter's name will continue that pattern is, for now, a question the household has not answered.
