Angel is one of those names that has a very different trajectory for girls and boys. As a female name, it was most popular in the US from the 1970s until the turn of this century, almost breaking into the Top 100 at its peak in 2001 but then beginning a long slide down the list.
This may be partly because other forms of Angel -- Angela, Angie, Angelica, Angelina -- have dropped from favor too. Or it may be because of the crossover popularity of Angel for boys, partially inspired by Buffy the Vampire Slayer.
As a boys' name, Angel entered the Top 100 in 1997 and remains there today.
Spice Girl Melanie Brown named her daughter Angel Iris.

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.
 Anna is the Latin form of Hannah, a Hebrew name that derived from root chanan, meaning "grace." European Christians embraced the name for its associations with the Virgin Mary’s mother, Saint Anna — known in English as Saint Anne.
Anna has been used for generations throughout Europe, from Russia to Italy, Spain to The Netherlands. While Hannah and Anna are the most common forms of the name, variations including Annie, Annalise, Anya, Anika, Nancy, and Anais also rank in the US Top 1000.
 
Classic and simple, Anna would be an excellent choice for parents in search of a name that will bridge two different cultures, say Jewish and Italian.
 
In literature, Anna is associated with Tolstoy's Anna Karenina. The name was given some fresh life when it was used for the adorable younger sister voiced by Kristen Bell in the animated film Frozen. Three current bearers are actresses Anna Kendrick, Anna Friel, and Anna Paquin.
 
Anya takes it more into international territory, and Anja, even further. Read more about Anna and other <a href="https://nameberry.com/blog/disney-princess-names">Disney Princess Names</a> in our featured blog.

Who knew there were so many soccer fans in the U.S.? Beckham -- as in British sensation David -- has exploded onto the baby name scene in the past decade.

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. 
 Along with the US, Chloe has been also mega-popular throughout the English-speaking world and is also a top girls' name in Spain, Italy, Chile, and the Netherlands. The creative spelling Khloe has been moving up as well, thanks solely to the Kardashian klan.
 Chloe appeared in Greek mythology as an alternative name for the goddess of agriculture and fertility, Demeter. She was referred to as Chloe in the spring months, due to the name’s relation to sprouts and growth. Chloe is also mentioned in the New Testament as the name of a Greek Christian woman. 
 
While Chloe has not been used for any recent celebrity babies, it is the name of the now-grown daughters of Olivia Newton-John and of Candice Bergen and the late French film director Louis Malle. Actress and style leader Chloe Sevigny is another high-profile bearer, as is rising young star Chloe Grace Moretz.
 Chloe is a titular character in the Greek pastoral romance Daphnis and Chloe, appears in Uncle Tom's Cabin, and is the real name of Nobel prize-winning writer Toni Morrison.

An medieval English form of Helen, the sensitive but clear-eyed Ellen has swung in and out of style for centuries, often alternating with the parent name. Ellen was the more common in medieval England, until after the Renaissance, when Helen overtook her. In Edith Wharton's The Age of Innocence, set at the end of the nineteenth century, one character wonders why another has not changed her "ugly" given name to something prettier, like Elaine—a statement few would make today.
 Ellen has been the name of two First Ladies—Arthur and Wilson—and is Scarlett O'Hara's mother in Gone with the Wind. These days, it's most strongly associated in the US with comedian and talk show host Ellen DeGeneres.

Ellen

Grace, a simple and pure virtue name which originally referred to divine grace, is a fashionable classic. In the early 2000s, it seemed headed for the Top 10 but pulled back from the upward trajectory, which you may consider a very good thing.

Grace is one of the most luminous of names, recalling the cool elegance of Grace Kelly, Princess of Monaco. Embraced by Americans of the Victorian era, it was the eleventh most popular name in this country in 1875 and has always ranked among the Top 1000 girl names.

Currently, Grace is the Number 1 girls’ name in Ireland, and ranks highly in other English-speaking countries. In the US, it’s one of the most popular one-syllable middle names for girls.
 
Grace is derived from gratia, the Latin word for "grace." It existed as Gracia in the Middle Ages but was not in common use until the Puritans adopted it along with other Christian attribute names in the sixteenth century. It was used as a <a href="https://nameberry.com/list/373/virtue-names">virtue name</a>, in reference to divine grace — the love and kindness of God.
 
If Grace is too overused for you, consider an international variation like Engracia or Graziella. Some parents have even migrated into the gender neutral camp in search of Grace equivalents such as Gray or Grayson or even Gracelyn. Choosing the nickname Gracie for the birth certificate is a popular option.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a>. 
Jack is a derivative of John that originated in medieval England. The name went from John to Johnkin to Jankin to Jackin to Jack. The name was so common in the Middle Ages that Jack became a generic term for a man. 
 
Jack is familiar to all from earliest childhood via Jack and Jill, Jack Sprat, Jack and the Beanstalk and Little Jack Horner et al. It is still a recent favorite for novel, TV and movie characters. 
 
Jack is at the top of the charts in Ireland and Scotland, and also ranks highly in Germany, Sweden, the Netherlands, and Belgium.
 
The jaunty Scottish version is Jock.

Jack

Judy was the nickname of choice for almost all the Judiths born in the 1940s and 50s; today's little Judiths are much more likely to be called Judith -- or, possibly, Jude. 

Judy

Karen is a Danish diminutive of Katherine, an English name derived from the Greek Aikaterine. The etymology of Aikaterine is contested, but generally considered to have arisen from the Greek root katharos, meaning "pure." Kaja is a related name, as it is another Danish variation of Katherine.
 
Karen, a sweet good-girl Danish import, was so popular during the baby boom (Karen was Number 3 in 1960) that it's locked firmly into fashion limbo today. Recently, the name Karen has been turned into a meme, representing a hostile white woman—one who usually wants to speak with the manager.
 
Parents who want to honor a Karen or choose an updated version of the name might want to consider the Irish Kieran, the Cornish Kerensa or Kerenza, or variations from Karina to Kyra.

Karen

Once the quintessential bouncy teenager name, Kelly helped launch the trend of unisex <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> . But it now takes a backseat to more substantial surname names like Kennedy.

Kendra was once seen as a feminization of Kenneth -- but it's now firmly established as a standalone. American parents can't seem to make up their mind about it though: it was one of 2013's fastest-rising names, entering the Top 200 for the first time since 2000, but then it tumbled again.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.
 
Today, the Luke constellation of names is more popular than ever, with the ascendance of Top 10 Lucas and international star Luca. Luke ranks third in the group, but still stands in the US Top 50 and the Top 100 throughout the English-speaking world.
 
Luke originated as a short form of Lucas, a Latin derivation of the Greek name Loukas. The most famous bearer of the name is the first-century Greek physician—an evangelist and friend of Saint Paul, as well as the author of the third Gospel of the New Testament—who was also supposed to have been a portrait painter. He thus became the patron saint of doctors and artists.
 
Later Lukes have included Luke Duke of The Dukes of Hazzard, Cool Hand Luke, half of the classic soap opera duo of Luke and Laura, contemporary actors Luke Wilson and Luke Perry, and a number of star athletes.
 While Luke, Lucas, Luca, and the French Luc all have the same root and meaning, Lucius and Lucian have a different origin and meaning -- the more evocative "light".

Margo and Margot sound exactly the same, so why has the Margot spelling hopped back onto the Top 1000, outpacing Margo in numbers more than two to one? (Over 350 baby girls were named Margot in the most recent year, versus 150 named Margo.)

Credit the Gwyneth Paltrow character Margot in The Royal Tennenbaums and hot Australian star Margot Robbie. And maybe to some parents, the Margot spelling seems more like a complete name.
But it may also create some pronunciation confusion. And Margo gives you the same blend of fashionable o-ending and classic feel.

Margo

Megan originally evolved from Meg, which itself derived as a nickname for Margaret. Margaret ultimately comes from the Greek word margarites, meaning "pearl." Megan is no longer a common nickname for Margaret—it is most often used as a full name. Other spellings include Meghan, Meagan, Megyn, and Meaghan.
 
One of the most popular <a href="https://nameberry.com/baby-names/172/welsh-names">Welsh names</a> ever in the US—it was Number 10 in the 1990s—Megan is still widely used today, but waning. It fell to its lowest ranking in 50 years in 2017. Actress Megan Fox has upped its glam factor. We've yet to see how the popularity of the new Duchess of Sussex, Meghan Markle, affects all the spellings of her name.

Megan

Monty, a name with a World War II feel, is rarely used on its own.  But we're hearing rumblings of a comeback and think that Monty, whatever it's short for, is an adorable vintage nickname name of the future.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four <a href="https://nameberry.com/search/girls-names/o">girl names starting with O</a> on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen. 
Olive has positive associations to the olive branch as a symbol of peace and the ancient olive wreath that celebrated success.
 Olive was the name of the adorable Abigail Breslin character in the popular movie Little Miss Sunshine. Olive Chancellor is a major character in Henry James's The Bostonians and Olive Kitteridge is a Pulitzer Prize-winning Elizabeth Strout novel that was adapted into a TV miniseries in 2014. Kids might be familiar with Olive the Other Reindeer.
 Olive came into fashion at the end of the nineteenth century along with other botanical names, when it had a run in the Top 100.

Olive

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage. The birthstone for the month of June, Pearl could also make a fresher middle name alternative to the overused Rose. Cool couple Maya Rudolph and Paul Thomas Anderson named their daughter Pearl Minnie, followed by Jack Osbourne, and several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .
After being a Top 25 name in the late nineteenth century, Pearl went into a long slide, but is showing signs of a strong comeback -- it reentered the Top 1000 in 2010.
 In Nathaniel Hawthorne's The Scarlet Letter, Pearl is the illegitimate daughter of Hester Prynne, who gives her the name because she is 'her mother's only treasure.'
 Pearl was also the alter ego name of Janis Joplin, tied to singer Pearl Bailey, and---hmm--the birth name of western writer Zane Gray.
 Variations are PERLE and PERLA.

Pearl

Like Peggy and Patsy, the kind of zesty moniker young Judy Garland would sport in her early let's-put-on-a-show flicks. It fell out of favor (and the Top 1000) for a while, but has recently rebounded by reentering the charts in 2013. Expect it to continue gaining traction as a result of surprise hit Penelope.

Penny

As sweet-smelling as Rose but with an international flavour, Rosa is one of the most classic Portuguese, Spanish and <a href="https://nameberry.com/baby-names/166/italian-names">Italian names</a>, which is also favored by upper-class Brits, having an ample measure of vintage charm. Rosa has been on the popularity charts for every year that's been counted, especially popular from the 1880s through the beginning of the twentieth century. 
 The name of a thirteenth century saint, Rosa has several other notable namesakes. In literature, she was a character in David Copperfield. Rosa Parks is a Civil Rights icon, Rosa (born Marie-Rosalie) Bonheur was a noted nineteenth century French artist, Rosa Ponselle an American operatic soprano and Rosa Luxemburg a left-wing activist. In the modern world there have been several Rosas in video games, including Final Fantasy IV.

Although Susan had her heyday from the thirties to the sixties, and is now common among moms and new grandmas, and though most modern parents would prefer Susanna/Susannah, we have spotted some flickers of interest in a revival. It still retains a certain black-eyed-Susan freshness.
 
Susan has a substantial literary resume, including appearances in George Eliot's Mill on the Floss, Anthony Trollope's Barchester Towers, Thomas Hardy's The Mayor of Casterbridge and Jude the Obscure, and Charlotte Bronte's Shirley.
 
Susan's many nicknames include Sue, Susie, Suzy, Sukie, and Zuzu—many of which have been celebrated in song. Among Susan's notable namesakes are activist Susan B. Anthony, writer Sontag, and actress Sarandon.
