Middle Name Girl

Arlo, an unexpectedly popular name for boys these days, is also finding new life as a girls' name. The first name Arlo may be rooted in the surname Arlow or the place name Aherlow, meaning "between two highlands". As a surname, it also has roots in a place name meaning "rocky hill".

Arwen is well known as princess of the Elves in Tolkien's Lord of the Rings. The author took inspiration from Welsh for many of his character names, and indeed Arwen and its masculine counterpart Arwyn do have a modest history of use as legitimate Welsh names, deriving from the -wyn suffix ("fair, blessed") plus an intensifying prefix.

Bellamy is emerging as an up-and-coming girls' name, an Irish surname-y riff on the super-popular Bella series of names. While the Bella connection makes Bellamy sound a little trendier and more popular than it really is, we see the name possibly rising through the ranks for both genders in the coming years.

Very popular in Wales, this perfectly nice name's only problem is its similarity to the dated Beth Ann.

Bronwen is widespread in Wales, but still rare enough here to sound somewhat international — we think Bronwen is a real winner. (Note: the Bronwyn spelling is an Anglicization, since the -wyn ending is masculine in Welsh).

Cleo, one of the few girls' names to boast the cool-yet-lively o ending, is of course short for Cleopatra, the name of one of the most powerful women in history.

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.

This name of a character played by Kirsten Dunst in the movie Virgin Suicides, originally a novel by Jeffrey Eugenides, is gaining attention, also thanks to the heroine Lux, Lady of Luminosity in the League of Legends games. Luz is the Spanish version.

Lyra is a name with ancient and celestial roots that's finding new popularity thanks to its starring role in Philip Pullman's His Dark Materials series, seen in the movie The Golden Compass. Simple yet unique, Lyra hits the sweet spot between too popular and too unusual.

Mae, a sweet and springlike old-fashioned name, hadn't been on the national charts in forty years, but finally made it back in 2010. Mae is derived from May, the month name that was chosen for its connection to Maia, the Roman goddess of growth and motherhood.

Maeve is a short and sweet name that has become one of the most stylish Irish names for girls in the modern US. Maeve would make an excellent first or middle name choice, with more heft than Mae/May and more modern charm than Mavis.

Simone, the elegant French feminization of Simon, strikes that all-important balance between unusual and familiar, and it's oozing with Gallic sophistication. Dwayne "The Rock" Johnson has a daughter named Simone; Chris Rock used it in the middle place for his daughter, as did Kevin Kline and Phoebe Cates

Although Sylvia seems to be having somewhat of a revival among trendsetting baby namers, we'd still opt for the even gentler and more unusual Sylvie. Despite being dated in its native France (where it was popular during the 1950s and 60s), in English-speaking regions it still feels fresh and international without being unfamiliar and has a cosmopolitan, international air. It debuted on the US Top 1000 in 2016.

Classified as an early beauty, Zelda has long and often been used as such for characters in books and films. Since 1986, Zelda has been a prime Nintendo name, as in the Legend of Zelda: Twilight Princess.
