Alternatives to Charlie

Charlotte, the name of the young Princess of Cambridge, is the latest classic name to join Sophia, Emma, Olivia, and Isabella at the top of the popularity list. It is now among the most popular girl names in many English-speaking and European countries.

Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Chloe is a pretty springtime name symbolizing new growth. Though slightly off its peak in the Top 10 in 2010, Chloe still ranks in the Top 20 and is solidly a modern classic.

Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.

Thea is a diminutive of names ending in -thea, including Dorothea, Althea, and Anthea. It is also the Anglicized spelling of Theia, the Titan of sight, goddess of light, and mother of the moon. She was the consort of Hyperion, and mother of Helios, Selene, and Eos.

Quinn is one of the first popular Irish unisex surnames, a strong and attractive choice on the rise for girls but still popular for boys. Quinn was used for about 2600 baby girls and 600 boys in the US last year.

Willa has become increasingly fashionable, with its combination of Willa (born Wilella) Cather-like pioneer strength and the graceful beauty of the willow tree.

Ellie first took off in the UK—yes, in this nickname form—and this warm and friendly name has also become hugely popular here. In 2011, Ellie entered the US Top 100 girl names for the first time and has remained near the top of the charts ever since.

Evie was derived from the English Eve or the Latin Eva, which in turn come from Chawwah, a Hebrew name related to the concept of life. Evie can be used as a nickname for any name that starts with Ev-, including Eva, Evelyn, and Evangeline, but also for names such as Genevieve and Maeve. Evie is typically pronounced with a long E sound, but a short E is also valid.

Charlie is a friendly, boyish nickname name now used slightly more frequently for girls than boys, with over 2200 baby girls named Charlie last year versus about 2100 boys. That makes Charlie one of the most evenly-balanced and most popular unisex names around today.

A hot starbaby name – chosen by Kelly Ripa, Chris Rock, Lisa Bonet, Denise Richards and Charlie Sheen, Carnie Wilson, and Annie Lennox, and used as the nickname of Madonna's Lourdes – Lola manages to feel fun and sassy without going over the top. Be warned, though: "Whatever Lola wants, Lola gets," to quote a song from the show Damn Yankees.

Eden is an attractive, serene name with obvious intimations of Paradise, one of several place names drawn from the Bible by the Puritans in the 17th century.

Georgia is so rich, lush and luscious, it's almost irresistible. Georgia's now a rising star among the feminizations of George, helped by associations with the southern state (named for British King George II) and painter Georgia O'Keeffe, with the Ray Charles song "Georgia On My Mind" or maybe "Sweet Georgia Brown" playing in the background.

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

Lottie is a nostalgic great-grandma name that conjures up lockets and lace, and — like Nellie, Josie, Hattie, Tillie, and Milly — has considerable vintage charm.

Remi is an adorable name that's fashionable and keeps gaining momentum. Remi entered the US Top 1000 in 2013 and is now approaching the Top 100.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.

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.

Marlowe is very much in the air, with its lovely -o ending and the modern twist it offers on the likes of Margaret, Margot, Martha, and Marlene. But is it Marlowe, Marlow, or Marlo? Well, for a girl in the US at least, it's probably Marlowe, with this spelling the only one to appear in the Top 1000.
