One of the most evenly divided unisex names these days; strong and energetic, if overused, for both genders. 

Alex

Cute nickname of Angela and other angelic names, Angie is now being used on its own, although its popularity has fallen in recent years. That said, Angie is one of those surprising classics, hanging on in the girls' Top 1000 continuously since its inception in 1880.

More colorful than Blanche, but blanker than Bianca.

Brooke variation – or is the other way around? – that makes it more a nature name, less an eighties-style androgynous name.

Carrie lives on mainly on the screen, as the new/old antiheroine of Stephen King's classic Carrie, as turn-of-the-21st-century diva Carrie Bradshaw of Sex & The City, and as Claire Danes' Emmy-winning character Carrie Mathison of Homeland. In real life, however, Carrie dropped off the Top 1000 a handful of years ago and, while the name retains some charm, shows no signs of making an imminent comeback. Try Cara instead.

Cindy as a name in its own right made it into the Top 20 in 1957 and remained a Top 200 girls' name until the end of the 20th century. Although it's fallen precipitously since then and left the Top 1000 completely in 2015, Cindy remains a name commonly heard in the US. Today, though, it would more likely be attached to moms or grandmas than to babies. 

Whether as a short form or a nickname used on its own, Cindy along with other popular nickname-names of its era -- Debbie, Kathy, Judy -- has faded from fashion to be replaced by the stylish nickname-names of this era, such as Ellie and Charlie.

Galina

Has been used on its own since the 1920s, but still seems like only part of a name. Was very much tied to mid-century Italian sexpot Gina Lollobrigida.

Gloria is beginning to move beyond its de-glamorized Grandma image, most recently thanks to glamorous young Hollywood parents Maggie Gyllenhaal and Peter Sarsgaard, who chose it for their second daughter. Gyllenhaal was quoted as saying they had been inspired by Patti Smith's rendition of the Van Morrison song "Gloria" at a concert and thought " 'We'll name our daughter that one day'."
 George Bernard Shaw was one of the first to use this form of the ancient Latin name GLORIANA in his 1898 play You Never Can Tell It was a Top 25 name in the Gloria (born Josephine) Swanson era of the 1920s,--reaching as high as Number 20 in 1925-26) and held on in the Top 50 until 1955.
 Most prominent current adult bearers: Gloria Steinem and Gloria Estefan. Glorias have also figured prominently in TV sitcoms--as Archie and Edith's only child on All in the Family and the sexpot character played by Sofia Vergara on Modern Family.

Joe is still the ultimate good-guy name, not at all diminished by its longevity or popularity or its everyman rep as Regular Joe, Cowboy Joe, G.I. Joe, Joe Exotic, Joe Blow, Joe Millionaire, Average Joe — and now President Joe (Biden). 
 There are millions of Josephs who have gone primarily by the nickname Joe; just a few of the more prominent Joes are Biden, Namath, Torre, Di Maggio, Lieberman, Montana, and Jonas.
 Several celebrities have chosen Joe as a full name for their sons, including Kate Winslet, Kevin Costner, Sting, and Stephen King.
 While Joe and long-form Joseph have always been among the most common male names in the US, there was never a President Joe until Biden.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.
 
John is an English derivative of the Hebrew name Yochanan via the Latin name Iohannes, itself coming from the Greek Ioannes. John was a key name in early Christianity, borne by John the Baptist, John the Apostle and John the Evangelist, plus 84 saints and 23 popes, as well as kings and countless other illustrious notables. Contrary to popular belief, the names John and Jonathan are unrelated, the latter being an elaboration of Nathan.
 
Because many of today's baby Johns get their names for familial rather than stylistic reasons, John isn't as ubiquitous as it once was. For modern parents, the nickname Jack or an international form like Gianni feels much fresher. But John is still one of the Top 10 <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a> of all time.
 
The international versions of John are perennial classics in their own cultures: the French Jean, the Irish Sean, the Scottish Ian, the Welsh Evan and Ewan, the Italian Giovanni, and Gianni the Spanish Juan, the German Johann/Johannes, the Slavic Jan, the Russian Ivan, and on and on.
 
Celebrities who have gone with the timeless John include Michelle Pfeiffer, Bono, Johnny Depp, Lauryn Hill, Bridget Moynahan, and Rob Lowe.
 
Jon may be an abbreviated spelling of John or a short form of Jonathan.

John

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.

One of the quintessential midcentury combination names, Leanne was spelled any number of ways: Lianne, LeeAnn, Leigh-Anne, and so on.  Like many similar combo names -- Joanne, Maryann -- they're all dated now.

One of those names like Pamela, Vanessa and Wendy, Lorna was invented for a particular literary character--the protagonist of the 1869 novel Lorna Doone by R. D. Blackmore--and then perpetuated as the name of a shortbread cookie. 
The author claimed to have based it on the Scottish place-name, Lorn. In baby name limbo for quite some time, it was chosen by Judy Garland for her younger daughter, Lorna Luft. Lorna Simpson is an important contemporary American artist. 
While not strictly from Scotland, many consider Lorna to be one of the most tradtional <a href="https://nameberry.com/list/472/scottish-names-for-girls">Scottish names for girls</a>

As a highly popular <a href="https://nameberry.com/girls-names">girls’ name</a> in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used <a href="https://nameberry.com/search/girls-names/m">girl names starting with M</a>.
 This widespread name understandably has produced notable namesakes in almost every field – opera's Maria Callas (born Sophia Cecelia), tennis's Sharapova, education's Montessori, ad infinitum. And she's been celebrated in song as well, from Ave Maria to the eponymous song in West Side Story to "How Do You Solve a Problem Like Maria?" in The Sound of Music. 
While the usual English pronunciation these days is the same as it is in non-English-speaking countries – mah-REE-ah – the British used to pronounce it mah-RYE-ah, like Mariah Carey.

 Maria ultimately dervies from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Used especially in Latin America, this would make a funky spin on Maria.

Piper is a bright, musical name that entered the list in 1999, one year after the debut of the TV series Charmed, which featured a Piper, and it's been a consistent riser since. Piper Kerman is the memoirist whose prison experiences provided the basis for the hit Netflix series Orange is the New Black.
 Piper has been chosen by several celebs for their daughters, including Gillian Anderson and Cuba Gooding, Jr., and is now one of the top <a href="https://nameberry.com/search/girls-names/p">girls' names starting with P</a>.
 One of the first Pipers on the scene was Piper Laurie (born Rosetta), after whom actress Piper Perabo was named.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys.

Sam is one of the most popular <a href="https://nameberry.com/search/baby-names-starting-with/s">names that start with S</a> in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty. 
 
Derived from sophia, the Greek word for wisdom, the name was first famous via St. Sophia, venerated in the Greek Orthodox church—St. Sophia was the mother of three daughters named Faith, Hope and Love. It was first used in England in the seventeenth century and was the name of George I's both mother and wife.
 
Like its sister baby girl names Isabella and Olivia, Sophia has gained widespread favor by appealing to a broad range of parents: Intellectuals who like it for its meaning and those attracted to its femininity, parents who want a classic name and those looking for a name with Latin roots—the Sofia spelling is also popular. Sophie is the French version of the name, more popular than Sophia in some parts of the world. Legend Sophia Loren was originally Sofia.
 
Sophia has been an author favorite from the days of early novelists like Henry Fielding (Tom Jones) and Jane Austen (Persuasion) to the TV scriptwriters of today (The Walking Dead, Orange is the New Black).
 
Sophia's only downside is its huge popularity; it's actually even more popular than it appears, because alternate spelling Sofia falls in the Top 20 on the US popularity chart. Alternative baby names you might want to consider: Sophie, Seraphina, Susannah, Zofia.

Suzanne became popular along with Susan but has just dropped out of the Top 1,000. Wait a generation (or two) in the US, though in France Suzanne is once again tres chic.

One of the first luxury brand names and the quintessential Booming Eighties status-conscious moniker; used by Donald Trump for his daughter, Tiffany has plummeted far from its high in the Top 25.
 
Tiffany first entered the Top 1000 in 1962, following the release of Breakfast at Tiffany's in 1961.
