Fiona entered the American consciousness with the opening of the 1954 Broadway musical Brigadoon, but didn't come onto the U.S. popularity list until 1990.

Best known as the princess of the Elves in Tolkien's Lord of the Rings, Arwen is a fantasy-inspired choice that feels perfectly down to earth. In 2022, it entered the UK Top 400, making it one of the fastest rising names, more than doubling in use from the previous year.

Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations — with Adalynn and Adalyn also popular — that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive.

Magical and earthy, sophisticated but off-beat, Persephone appears as the daughter of Zeus by Demeter in Greek mythology. After she was kidnapped by Hades to be Queen of the Underworld, it was decreed by Zeus that she would spend six months of the year with her mother, allowing crops to grow, and six in mourning, thus accounting for the change of seasons. As such, she is both the goddess of the Underworld and of Spring.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

For a long time, Isadora has been overlooked in favor of Isabella, owing perhaps to its association with the tragic modern dancer, Isadora Duncan, or because parents would rather their daughter be a Bella than a Dora. Now, with Theodora back in the charts and vintage names in vogue, Isadora has been slowly gaining more attention over the last decade.

Gemma is a jewel of a name, an Italian classic that was very popular in 1980s England, but has only recently been started to be used here; it entered the list in 2008.

A concise choice with a hint of chic, Sabine is the French, Dutch, and German form of the Latin Sabina. While it has never charted in the US, Sabine saw a slight increase in use in recent data, with 107 babies given the name (compared to 70 called Sabina).

Balancing femininity, vintage charm, and fantasy nerdiness, Marceline is one to watch. Marceline the Vampire Queen from the 2010-2018 animated TV series Adventure Time brought her elaborate French name back into public consciousness. It re-entered the Top 1000 in 2020, after an 86 year hiatus, and keeps rising. Nicknames Marcie and Marcy are rising in popularity as well. Marceline may appeal to parents who like frilly, traditional, and sophisticated names such as Josephine and Genevieve. Marcella is another variation to consider.

Vivienne is an elaborated Gallic version of the name Vivian, chosen first by Rosie O'Donnell for her daughter and then catapulted to superstardom when Brad Pitt and Angelina Jolie used it for their twin daughter. An adult namesake is the British designer Vivienne Westwood. Rosie O'Donnell also has a daughter named Vivienne, known as Vivi.

The luminous Ingrid Bergman's appeal was strong enough to lend universal charisma to this classic Scandinavian name, which has been somewhat neglected in the US. Even today, a child named Ingrid would be assumed to be of Scandinavian ancestry, signaling the name has never been fully integrated into the English lexicon the way other European choices from the same era like Danielle or Kathleen have.

Guinevere was the name of the beautiful but ill-fated queen of Camelot, for so many years eclipsed by its modern Cornish form Jennifer. Today, Guinevere could be a cool possibility for adventurous parents intrigued by this richly evocative and romantic choice.

Linnea is an attractive Scandinavian name that derives from the renowned 18th century Swedish botanist Carl Linnaeus, who developed the Linnean system of classifying plants and animals.

A strong, grounded choice that still has plenty of energy and charm, Leona is the feminine form of Leon, itself derived from the Greek word for "lion". Associated with courage, leadership, and royalty — and the star sign of July and August — Leona is popular in Croatia and Sweden, but familiar across the US, the UK, and continental Europe.

Althea is a poetic, almost ethereal name found in Greek myth and pastoral poetry, associated in modern times with the great tennis player Althea Gibson, the first African-American to win at Wimbledon.

One of the few remaining unrestored vintage gems, with a choice of two winning nicknames--the girlish Winnie and the tomboyish Freddie. Winifred, the name of a legendary Welsh saint, was a Top 200 name into the mid-1920's.

This old Scottish form of Helen has had quite a history, going from appearing as one of the shining heroines of the Arthurian legends, the princess who fell in love with Sir Lancelot and became the mother of Sir Galahad, referred to as 'Elaine the fair' and 'Elaine the lovable', to being the name of the most famous of New York's celebrity restaurants, to being the archetypal New York neurotic on Seinfeld.

The oldest-known form of Mary, serious and solemn Miriam has been a particular favorite of observant Jewish parents. But we can see it extending beyond that sphere into the next wave of Old Testament names post-Rachel, Rebecca, Sarah, Hannah, and Leah. Miriam is currently the Number 1 girls' name in Israel.

Octavia began as the Latin, then Victorian name for an eighth child. While there aren't many eighth children anymore, this ancient Roman name has real possibilities as a substitute for the overused Olivia; recommended for its combination of classical and musical overtones. It was chosen for his daughter by Kevin Sorbo.

Odessa, (transcribed as Odesa in Ukrainian) is a Ukrainian port city and was given its name by Catherine the Great, who was inspired by Homer's Odyssey. It would make an original and intriguing choice.
