Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

Emilia is the feminine form of the Roman clan name Aemilius, which derived from the Latin aemulus, meaning "rival." In Shakespeare’s Othello, Emilia is the wife of Iago and confidante of Desdemona. Amelia, although homonymous, has a different root and meaning.

Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

The ubiquitous French version of Mary came into the English-speaking world in the nineteenth century. In the United States, Marie was a huge hit at the turn of the last century and for the ensuing fifty years, becoming the seventh most popular name in the country for three years, from 1901 to 1904.

Anna has become the dominant form of the Ann family, offering a touch of the international to English speakers and a bit more style than the oversimplified Ann or Anne.

With mythological names rising, the handsome son of Zeus and god of medicine, music, and poetry among many other things might offer an interesting, and melodic option. Similar in style to Atlas and Atticus and similar in sound to Arlo, Paolo, Paul, and Ollie, Apollo entered the US Top 1000 back in 2012, and was propelled upwards after it was chosen by Gwen Stefani and Gavin Rossdale in 2014.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

Serene Irene, the name of the Greek goddess of peace and one of the most familiar Greek goddess names, was hugely popular in ancient Rome and again in the United States a hundred years ago.

Carmen has long been associated with the sensuous, tragic heroine of Bizet's opera, based on a novel by Prosper Merimee; more recently it has called to mind two other bombshells: Carmen Miranda (born Maria) and Carmen Electra (born Tara), as well as the great jazz singer Carmen McRae. In the celebrity baby name world, this classic Spanish name for girls was used by Hilaria and Alec Baldwin for their oldest daughter.

Three syllables in only four letters is quite a feat, but that's exactly what you get with Ilia, a versatile, unisex option with various origins. It could derive from the Greek Iliana, which could denote someone from Illium, or it could be a feminine form of Ilian, a form of Elijah. Alternatively, it is a Basque form of Julia, or a Bulgarian feminine form of Ilya, with again links back to Elijah. Currently a gender neutral option in the US, it may be exclusively masculine elsewhere.

Minerva is the long-neglected name of the Roman goddess of wisdom and invention, the arts and martial strength, one of the mythology names for girls that might appeal to adventurous feminist parents. With Juno and Jupiter, she made the Capitoline triad, whose worship was at the very center of Roman religion.

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.

Giovanni is a venerable Italian classic that suddenly sounds fresh and cool. Ubiquitous in Italy, it has countless notable namesakes, from writer Boccaccio to designer Versace (nn Gianni).

Can you hear the drums Fernando? Although 58% of Nameberries prefer Ferdinand to Fernando, the Iberian variant has a softer, more romantic feel that makes it a better fit with all those Javiers, Lorenzos and Matteos.

Angelica is by far the choicest form of the angelic names -- more delicate than Angelina, more feminine than Angel, more modern than Angela. But though Angelica is so lacy and poetic, it lags behind the bolder Angelina (probably for obvious reasons).

Orlando, the ornate Italianate twist on the dated Roland, with a literary heritage stretching back to Shakespeare and before, has appealing book-ended o's, and is open to combination with almost any last name, a la British actor, Orlando Bloom.

Belinda, cousin of Linda and Melinda, enjoyed a brief return to the Top 1000 from 2005 through 2013, only to fall off again in 2014. A name that some may consider a modern spin on the midcentury popularity queen Linda is in fact a classic with deep and fascinating roots. In Babylonian mythology Belinda was the goddess of heaven and earth, and the name later was used for the heroine of Alexander Pope's satirical poem The Rape of the Lock.

After half a century, this otherwise feasible name has at last started to lose its link to the friendly ghost; it certainly didn't scare model Claudia Schiffer, who chose it for her son, as did Atomic Kitten Jenny Frost. Iconoclastic namer Jason Lee switched genders and called his daughter Casper. Also related to the revived Jasper, Caspar seems headed towards the path to a similar resurgence.

With Violet in vogue, this vibrant international variation has been on the rise since the 2010s. Vintage and floral like its more popular sister, Violetta has a slightly softer sound and a touch of extra flair. Given to 135 girls in a recent year, it also gets you to nicknames Etta, Vita, and Lettie.
