Princess Eugenie and her husband, Jack Brooksbank, announced Monday that they have named their newborn daughter Adelaide Elizabeth Annina. The infant was born on Aug. 3 in Lisbon, Portugal, weighing 6 pounds and 9 ounces (3 kilograms).
The child is the third for the couple, who also have two sons, five-year-old August and three-year-old Ernest. Princess Eugenie, the younger daughter of Prince Andrew and Sarah Ferguson, is the niece of King Charles III.
According to a statement posted by the princess on Instagram, the names were chosen to honor three individuals and to reflect the child's English and Portuguese heritage. The name Elizabeth honors the late Queen Elizabeth II, while Adelaide was inspired by both Queen Adelaide, the wife of King William IV, and Maria Adelaide of Portugal. Annina is the name of a close friend of the couple.
The scale of this event is specific to the immediate royal family and the diplomatic ties between Britain and Portugal, where the birth occurred. For the approximately 67 million people in the United Kingdom and citizens of Commonwealth realms, the expansion of the royal family represents a continuation of the Windsor line. The choice of names connecting two European nations—the U.K. and Portugal—highlights the family's international ties, particularly as the child was born in Lisbon rather than London.
In terms of concrete day-to-day changes, the public will see the new name added to official genealogical records and the royal family's website. Following the announcement on Monday, the family indicated they have spent the last two weeks in private. The next formal steps will include the registration of the birth in both Portugal and the United Kingdom, ensuring the child's legal status and rights in both jurisdictions are documented according to standard civil procedures for citizens born abroad. No further public appearances or events have been scheduled at this time.
