This lovely name from Spenser's The Faerie Queene is borne by a character who represents married love. A related unusual-yet-usable choice: Amabel.

Aria is a multi-cultural name with two extremely popular versions: this more word-like one along with Arya, the spelling used for the feisty young heroine of Game of Thrones. There were about 6400 baby girls named Aria in the US last year alog with 2400 named Arya, which counted together places the name in the Top 10.
 
The light and airy Aria entered the list in 2000 and now ranks among the Top 25 girl names in the US. In Italian, Aria's literal meaning is air, while in Hebrew it's a form of Ari meaning lion. An Aria is a musical term denoting a kind of song or melody, often in an opera.
Aria is a Top 100 name throughout the English-speaking world and also ranks highly in France and several European countries -- though notably not in Italy or Israel. In Persian, Aria is a male name, and in Indian it is considered unisex. 
Aria is also an improbably cool saint's name. Saint Aria (or Arria) of Rome was an early Christian martyr.

Aura is a New Age-y word turned name turned contemporary slang for karm. In Greek and Roman mythology, Aura was the Titan of the breeze and the fresh, cool air of early morning. But at odds with her peaceful, well, aura, the mythological Aura is a tragic figure, ultimately transformed into a fountain by Zeus.
 At the end of the nineteenth century, Aura was not that unusual: she reached Number 511 on the Social Security list in 1882. Princess Aura was a character in the old comic strip Flash Gordon.
 Aura is currently popular in some areas of Central America. And for the first time since 1901, Aura has joined the US Top 1000 for girls in 2023. Time will tell if the slang meaning of Aura will help or hurt its popularity as a name.

Calista Flockhart may have made her variation of this beautiful Greek name familiar to modern Americans, but the even-edgier x version was the name of an earlier feminist heroine: a character in Kate Chopin's The Storm.

Cassia is related to the cassia tree, which has yellow flowers and produces a spice that can be a substitute for cinnamon. Keziah, the name of Job’s daughter in the Old Testament, derives from the name of the plant as well. Cassia also has ties to the Ancient Roman name Cassius, an Ancient Roman family name meaning "hollow." 
 
Cassia is one of the rare names that's truly unusual yet has a stylish feel. Cassia has the added attraction of the sweet smell of cinnamon, thanks to its botanical associations. We predict Cassia will become much more popular along with her brother names Cassian and Cassius. 
 
Keziah, the Biblical equivalent, is also due for rediscovery, while Kassia is the Greek spelling that ties the name to Saint Kassiani, a feminist heroine.

In Greek mythology, Elara was a lover of Zeus who gave birth to a giant son (ouch); it's also the name of one of the moons of Jupiter, giving it a celestial feel. Possibly derived from the Greek alara meaning "hazelnut" or "spear", it combines that favorite El- beginning with the popular -ara ending of Clara, Lara, and Amara, making it an all round appealing choice. Currently in the UK Top 1000, and on the rise in the US, it could be a fresher or less popular alternative to Ella, Lyra, or Laura.

Holly ranks just in British Top 50, but it's been out of favor here since the 1970s Era of Nickname Names. Still, the name may be on her way back as a rejuvenated nature pick.
 Jolly Holly has always been among the favorite <a href="https://nameberry.com/list/412/christmas-baby-names">names for Christmas babies</a>, evoking the symbolic shrub with dark green leaves and bright red berries. And Holly is the flower for the month of December, so it's also among the perfect <a href="https://nameberry.com/list/577/names-for-december-babies">names for December babies</a>.
 A memorable fictional Holly is the enigmatic heroine of Truman Capote's Breakfast at Tiffany's, Holly Golightly (almost named Connie, and with the full name Holiday), played indelibly by Audrey Hepburn. A real life one is actress Holly Hunter. Holly Short is a fairy character in Eoin Colfer's Artemis Fowl novels. And in Galsworthy's The Forsyte Saga, Holly and Jolly are siblings.

Like Violet, Lavender and Lilac, Ianthe is a purple flower name. Chosen by the poet Shelley for his daughter, Ianthe has a poetic, romantic, almost ethereal quality. In the ancient myth, she was the daughter of Oceanus, supreme ruler of the sea, and also a Cretan woman so beautiful that when she died the Gods made purple flowers grow around her grave.
 Iantha is also used.
 Ianthe was a favorite of the pastoral poets of the seventeenth century and then again in the early nineteenth. She appears in the works of Shelley, Barbara Pym and Georgette Heyer. Writer Richard Brautigan named his daughter Ianthe.

Ianthe

This unusual Greek flower and color name has gained considerable recent attention via actress Ione Skye, who is the daughter of sixties folksinger Donovan.
 Ione was one of the fifty sea nymphs — Nereids — in ancient Greek mythology.
 Parents attracted to newer I-names like Isla might want to consider the distinctive Ione. The English pronunciation usually starts with the long I, while in the Latin languages such as Italian it starts with the long E sound.

Isis has gone from magical, feminist name on the rise to the forbidden list because of the extremist terror group called ISIS, an acronym for Islamic State of Iraq and Syria. Unsurprisingly, Isis was one of the fastest-falling names in 2014, dropping 130 ranks to reach #706. Interestingly, however, since 2020, it has begun to see increased use again, and 2023 saw it given to 151 girls.
 Before the rise of the political group, Isis was best known as the name of the supreme Egyptian goddess of the moon, sky, magic, motherhood and fertility, revived by feminists and others willing to cross into arcane territory. And with the mini-craze for names that start with Is- -- Isabella, Isla -- it was not so surprising that Isis was joining the crowd.
 The ancient Isis, wife of Osiris (who happened to be her brother), was worshiped beyond Egypt into the Greco-Roman world. According to myth, the Nile river floods every year because of Isis's tears of sorrow for the death of Osiris.
 In popular culture, Isis has been a character on Stargate and Battleship Galactica, an opera, the title of a Bob Dylan song and the name of several rock bands. The Isis is also the name given to part of the River Thames.
 
If you love the sounds or vibes of Isis, you could consider Ismay, Isolde, Eirlys, Ailish, Maelys, Ione, Inez, Iskra, Ismene, Atalanta, Artemis, Athenais, Anuket, Keziah, or Ianeira.

Lilith is derived from the Akkadian word lilitu meaning "of the night." In Jewish folklore she is portrayed as Adam's rejected first wife, who was turned into a night demon for refusing to obey him. Lilith is unrelated to most other Lil- names, with the exception of Lilita, which is the Latvian variation.
 
In spite of its gently pleasant sound, Lilith had for the most part been rarely heard outside of reruns of Cheers and Frasier until its recent rise up the charts. It entered the Top 1000 in 2010 and has risen in recent years.
 Lilith's demonic aura has followed her through popular culture in various fantasy novels including George MacDonald's 1895 Lilith, comics such as Neil Gaiman's Sandman series, TV shows like True Blood, comics, anime, and numerous video games.
 But that could be changing, in part due to Lilith Fair, the all-female traveling music festival organised by Canadian singer Sarah McLaughlin, which has raised millions for women's charities. Lilith may also ride the coat-tails of the resurgence in (non-related) Lily names.

Lilith

Paz, currently represented by actresses Paz Vega and Paz de la Huerts, would make a sparkling middle name choice. It originated as a title of the Virgin Mary, Our Lady of Peace, and is one of the <a href="https://nameberry.com/list/411/baby-names-that-mean-peace">names that mean peace</a>, derived from the Latin word "pax".
 Pazia is an attractive elaboration, while Pazit (pronounced Pah-ZEET) and Pazya are Hebrew variations. Paz in Hebrew means "gold".

Seren, meaning "star", is one of the <a href="https://nameberry.com/girls-names">top girls' names</a> in Wales, but as a boys' name it has a different derivation. It's a rare Polish form of the Latin Serenus, meaning "serene". It could make for a handsome and almost unknown alternative to rising star Soren.

Thora, related to Thor, is the ancient Norse thunder goddess name that's much softer and gentler than its meaning suggests. A noted bearer is actress Thora Birch.

Valentine is an attractive Shakespearean name with romantic associations, but those very ties to the saint and the sentimental holiday have sent it into a decline, one which we think may be about to turn around.
The name's best known bearer is the third century martyr St. Valentine, whose feast day of February 14 coincided with the pagan fertility festival of the goddess Juno, all of which led to the modern Valentine's Day. This makes Valentine one of the most perfect <a href="https:///list/630/70-lovely-names-for-february-babies">names for February babies</a>.
There are two Shakespearean characters named Valentine: one in Twelfth Night, and the other belonging to one of the two gentlemen in Two Gentlemen of Verona. 
Valentine was the name of the father of James Bond-creator Ian Fleming, the young Humphrey Bogart played a dashing con artist named Valentine Corliss in an early film, The Bad Sister, and Kevin Bacon was Valentine McKee in the 1990 sci fi movie Tremors. Valentine Michael Smith is a major character in Robert Heinlein's classic, Stranger in a Strange Land.
Though Valentine hasn't been in the U.S. Top 1000 for over half a century, it's currently in the Top 100 in France and Belgium.
Ricky Martin chose the even more romantic Latin Valentino for one of his twins, and the feminine Valentina was given to the daughters of Salma Hayek, Adriana Lima and Lolita Davidovich. And trivia tidbit: Valentine was the middle name of writer Henry Miller.

Valentine

X marks the spot in names these days, usually at the middles or ends of names, but here is one that puts it squarely up front.
 This extravagant name, which, like many Greek names beginning with X, is pronounced as if it were a Z in English, is derived from the Greek word for the color yellow. A Homeric epithet of Demeter, Xanthe would be a striking choice for a blonde-haired baby girl, thanks to its "golden" meaning.
