Princess Eugenie’s daughter finally has a name, and it’s already winning over royal fans. On Monday, Eugenie confirmed that her newborn girl is called Adelaide Elizabeth Annina. The announcement came two weeks after the baby’s birth in Lisbon, Portugal. Each name carries its own story, and together they tie two countries and three generations into one child.

The Royal Arrival in Lisbon

Eugenie welcomed her third child on August 3 in Lisbon. The baby girl weighed 6 pounds, 9 ounces, or about 3 kilograms. She joins two older brothers, August, 5, and Ernest, 3, rounding out a lively household. Because the birth happened in Portugal, the new arrival is one of the few modern royals born overseas.

Eugenie shared the happy update on Instagram rather than through a formal palace statement. “Two weeks ago today we welcomed our girl to the world,” she wrote. She added that the family has enjoyed “the most special, cosy and love-filled time” since the birth. That candid, personal tone matches how Eugenie has always spoken about motherhood.

Meaning Behind Adelaide’s Name

Every part of Adelaide Elizabeth Annina’s name has meaning. Eugenie explained the baby was named after three people “we love and admire past and present.” The choices also honor her English and Portuguese roots, since the family has strong ties to Portugal. Consequently, the name feels both personal and geographically fitting.

The first name, Adelaide, nods to two historical figures. One is Queen Adelaide (1792-1849), who was married to King William IV. The other is Maria Adelaide of Portugal, linking the name directly to the country where the baby was born. Together, these references quietly bridge Britain and Portugal in a single word.

Elizabeth, meanwhile, pays tribute to Eugenie’s grandmother, the late Queen Elizabeth II. Many royal babies carry this name forward as a mark of respect. Finally, Annina honors a close friend of the family. While the other names look to royal history, this one reflects a personal, private bond.

A Growing Royal Family

Eugenie is the younger daughter of the former Prince Andrew and his ex-wife, Sarah Ferguson. She is also a niece of King Charles III, placing her firmly within the wider royal family. However, Eugenie and her husband, Jack Brooksbank, have largely kept their children out of the spotlight. As a result, every family update tends to generate real public interest.

With Adelaide’s arrival, Eugenie and Jack now have three children under six. Older brothers August and Ernest will likely play a big role in welcoming their new sister home. For now, though, the family seems focused on enjoying the quiet, early weeks together, as their warm Instagram post suggested.

Princess Eugenie’s daughter arrives with a name that tells a story of family, history, and two countries. Adelaide Elizabeth Annina links a British queen, a Portuguese princess, and a cherished friend in one small child. It’s a fitting start for a baby already connected to so much. Fans will likely watch closely as more details about her life emerge over time.
