Annie is one of the most open and optimistic, the-sun'll-come-out-tomorrow type of name, having been celebrated over the years in song (Annie Laurie), comic strip (Little Orphan Annie), folklore (Annie Oakley, born Phoebe), and film (Annie Hall). It strikes a nice old-fashioned-but-jaunty chord that still has appeal, but we do suggest that you consider putting a more formal version on her birth certificate.

Celeste is a softly pretty and somewhat quaint name with heavenly overtones, which kids might associate with Queen Celeste of Babar's elephant kingdom. She's a light and lovely choice that's finally getting noticed.

Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

Sara, the streamlined form of Sarah, makes this ancient name feel more modern, but perhaps a bit lighter weight.

Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

A smooth, attractive choice, Arianna's on the rise with both single and double 'r's and 'n's. Single 'r' double 'n' Arianna — the second most popular version of the name — is these days associated with Greek-born blog queen Arianna Huffington.

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.

Amy is the English variation of the Old French name Amée—Aimée in modern French. Amée was a translation of the Latin name Amata, which derived from amatus, meaning "beloved." Other spelling variations include Amie and Ami.

One of the most romantic names, the lovely and stylish Juliet seems finally to have shaken off her limiting link to Romeo. In Shakespeare's play, it was Juliet who said "What's in a name?"

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.

Catherine is one of the oldest and most consistently well-used girls’ names, with endless variations and nicknames. The Catherine form feels more gently old-fashioned and feminine than the more popular K versions. Most stylish nickname for Catherine right now: Kate...or Cate, a la Blanchett.

Heidi became known — and popular — via the 1880 eponymous children's classic by Swiss writer Johanna Spyri and, despite decades of American Heidis of all sizes, shapes, and personalities, the name seems permanently tethered to that spunky little girl on the Alpine mountaintop in the book and Shirley Temple movie.

Matilda is a sweet vintage name that has been gently climbing the popularity list for the past 15 years, after a half-century slumber. The spunky children's book heroine Matilda is one factor in its rise, along with others of its class like Eloise and Caspian.

Laura is a hauntingly evocative perennial, never trendy, never dated, feminine without being fussy, with long-standing literary links. All this makes Laura a more solid choice than any of its more decorative counterparts and one of the most classic girl names starting with L.

Upbeat nickname-name that can't help but make you smile. You might want to use it as a short form for a more "serious" name such as Sunniva, but Sunny is undeniably, well, sunny.

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.

In the 1930s, Dorothy left Kansas and landed in the Land of Oz; by the '80s she had become a Golden Girl, living in Miami with roommates Blanche and Rose, giving her a decidedly older image. But parents today seeking a quiet classic are bringing Dorothy back—she reentered the Top 1000 in 2011 after almost completely disappearing.

Opal is on the verge of a repolishing, following other jewel names like Ruby and Pearl. A Top 100 name during the first two decades of the twentieth century, the opalescent Opal has a good chance of coming back as another O-initial option.

Maia was derived from the Greek word maia, meaning "mother." In Greek legend, she was the fair-haired daughter of Atlas who mothered Zeus's favorite illegitimate son, Hermes. To the Romans, Maia was the incarnation of the earth mother and goddess of spring, after whom they named the month of May. Maya is the more common spelling.

Lyra is a name with ancient and celestial roots that's found new popularity thanks to its starring role in Philip Pullman's book series, His Dark Materials and its subsequent movie and TV adaptions. Simple yet starry, Lyra is familiar but not overused in the US, where it ranks in the Top 500.
