Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden. 
All things considered, Aaron’s enduring popularity feels at once surprising and obvious. And endure it does. For the last 50 years, it has been a staple in the US Top 100, and it remains a solid favorite in a number of European countries, from France to Switzerland. 
The origins of the name are debated, with some saying from Ancient Egypt, and has the meaning “warrior lion”, while others believe it is derived from Hebrew, with meanings such as “high mountain” or “exalted”. 
In the Old Testament, Aaron is a powerful figure, acting as a spokesman for his brother, Moses. He produced miracles and plagues to intimidate the pharaoh for enslaving the Israelites, and he was appointed by God as the first high priest. 
Other notable namesakes include the American politician, Aaron Burr, the composer, Aaron Copeland, and actors Aaron Ekhart, Aaron Taylor-Johnson, and Aaron Paul. The name has literary credentials too, with Shakespeare, John Steinbeck, and George Eliot using it in their works. 
Given to more than 4500 babies in the US every year, the soft sound of Aaron’s double vowels continues to hold an appealing gentleness for parents today. 
But why does Aaron have that unusual beginning and why is it pronounced differently across the world? 
Well, the original Hebrew name is Aharon, pronounced with 3 syllables, however, this sound had no equivalent in Greek. When Jewish scriptures were translated then, it was recorded as “Aaron”. While the Romans and Greeks might still have said “a-ha-ron”, it was later Anglicized in the 17th century to “air-un”. 
In England however, it is often said as “a-run”, where “a” is like the first sound of “apple”. This is likely down to people confusing it with the English name “Aron”, or because they were influenced by the Scottish Isle of Arran and the Irish Aran Islands. 
More broadly, pronunciation varies when Aaron is translated into the many languages used around the world. In German, it is A-rawn, while in Finnish, it is AH-rone or Aaro. In Arabic, Urdu and Turkish, it becomes Harun or Haroon and across Africa, it might be Haruna or Haron. 
Love Aaron but slightly put off by its widespread popularity? You could try Alden, Ansel, Taran, Canaan, Ariel or Abram.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.
 Alexander is derived from the Greek name Aléxandros, composed of the elements aléxein, meaning "to defend," and aner, meaning "man." 
 
According to Greek legend, the first Alexander was Paris, who was given the nickname Alexander by the shepherds whose flocks he defended against robbers. He was followed by Alexander the Great, aka Alexander III, who conquered much of Asia.
 
A royal name in Scotland, Alexander is still highly popular there. In Gaelic, the name became Alasdair; in Spain, Alejandro; and in Italy, Alessandro.
 
The noble Alexander has led to the popularity of many spinoffs, such as Alex, Zander, Xan and Zan, along with female versions such as Alexandra, Alexis, and the unfortunate Alexa.
 Among the many notable Alexanders in history, standouts are Hamilton, Graham Bell, Fleming, Pope and Haig.
 Naomi Watts and Liev Schreiber's Alexander is known as Sasha.

Alyssa was in the Top 20 from 1997-2010 and peaked as the 11th most <a href="https://nameberry.com/girls-names">popular girls’ name</a> in 1998 and 1999 but has become less popular in recent years. It's related to the flower alyssum as well as to the classic Alice and variants. Alyssa Milano helped give it a bounce back when she was still a child sitcom star.

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).
 Angelica was introduced to England from Italy in the seventeenth cenury, and is heard in early poetry and plays, including Romeo and Juliet. Angelica Schuyler, played by Renee Elise Goldsberry, is one of the most appealing characters in Broadway sensation Hamilton.
 Anjelica is a variant spelling, as in Anjelica Huston.

Once a Top 100 name, this Spanish diminutive of Ana still retains some of her Latin flair. A notable namesake is noted attorney Anita Hill, another is the great jazz singer Anita O'Day. Plus there's Disney cred via the lead human character in 101 Dalmatians.

Anita

Cosette is best known as the heroine of Les Miserables. In the Victor Hugo novel, Cosette was the nickname given to the girl named Euphrasie by her mother. Although Hugo invented the name, some etymologists believe it's a spin on Colette, originally a female short form of Nicolas.


 Despite the popularity of Les Mis the musical, the name was given to only 138 girls in 2015 -- though it's worth noting that this is almost double the number from just a few years ago. Cosette would make for a sweet and quirky French choice.

Cosette

Edna is one of those names that, until what it seemed like a few minutes ago, felt so terminally frumpy that no one could imagine a parent choosing it for an innocent modern baby girl. But with the great upswing in names honoring ancestral family members, several of them being other four-letter, e-ending names, we wouldn't be so sure.
 Edna, which means delight, is a semi-biblical name--in the Apocrypha she is seen as a loving mother-- and was enormously popular in this country in the late nineteenth century, reaching as high as Number 11. It also relates to Eden--another, more contemporary sounding, option.
 Three literary bearers of the name are Edna St. Vincent Millay, Edna Ferber and Edna O'Brien, and to some the name might be identified with the campy character, Dame Edna Everage.

Edna

Eliza is a name with a wonderful combination of streamlined zest and Eliza Doolittle charm and spunk. It's a classic that's popular right now -- but not too popular.
 
Eliza has not been in the Top 100 since the 19th century and while it seemed like it was heading there again, it seems to have stopped just short of that mark. Which could be a very good thing.
 
Originally a diminutive of Elizabeth, Eliza eventually became a name in its own right. Despite its similarity to the Hebrew name Aliza, meaning "joyful," the two are unrelated. Eliza Schuyler Hamilton was the wife of Founding Father Alexander Hamilton, recognizable today as one of the lead characters in the musical Hamilton.
 Eliza is the name of one of the most vivid fictional characters, My Fair Lady's spirited Eliza Doolittle. Based on the George Bernard Shaw play Pygmalion, Eliza is transformed from cockney flower girl to elegant lady, played on stage by Julie Andrews and on screen by Audrey Hepburn. .
Pride and Prejudice's Elizabeth Bennett was often called Eliza; in Harriet Beecher Stowe's anti-slavery novel Uncle Tom's Cabin, Eliza is the intelligent and courageous protagonist
 Eliza Dushku is a charter member of the Joss Whedon rep company of actors, appearing in Buffy the Vampire Slayer, Angel, Dollhouse and Much Ado About Nothing. 
 One note: Do not name sisters Eliza and Isabel or Isabella, as they're different forms of mother name Elizabeth.

Eliza

Eponine is attracting new notice via the movie of Les Miserables, based on the book by Victor Hugo.  Eponine is the spoiled daughter of Cosette's foster parents whose name, according to the story, was lifted by her mother from a romance novel.  As in a romance, Eponine redeems herself by becoming a martyr to love.

For girls, typically used as a nickname for names such as Georgia and Georgiana, although Orange is the New Black stars Samira Wiley and Lauren Morelli recently used it as a full name for their daughter George Elizabeth. 
The adorable little 18th century girl in the Disney Plus series Renegade is called George.
In the Nancy Drew series, Nancy’s best friend is Georgia "George" Fayne.

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.

Margarita is an international form of Margaret that shares its meaning of "pearl", but also directly translates to "daisy" in Spanish and Greek. Despite being widely associated with the alcoholic beverage in English, it has a long history of use in Spanish, Greek and several Slavic languages — most notably being the name of the heroine of Mikhail Bulgakov's 1966 novel Master and Margarita. It currently ranks in the Top 30 girl names in Russia.

Although almost always feminine in the first name spot, Maria (and its French cognate Marie) are regularly used in the middle or in compound first names in Catholic cultures. Famous examples include Austrian poet Rainier Maria Rilke, Italian composer Giovanni Maria Nanino, and German fashion designer Guido Maria Kretschmer.

 
Maria ultimately derives 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).

Almost as popular in the 1950s among the Irish in Boston as it was with those back in Bray, Maureen was once among the most prominent <a href="https://nameberry.com/baby-names/509/irish-names-for-girls">Irish names for girls</a> in the US but has fallen from favor along with most of her een-ending sisters such as Eileen and Colleen.

Just when we had written off Peggy as the eternal perky, pug-nosed prom-queen she projected from the 1920s into the fifties, along came Mad Men, with intriguing mid-century characters with names like Joan and Betty--and Peggy, causing a bit of a re-think. MM's proto-feminist Peggy Olson was followed by Amy Adams's strong Oscar-nominated Peggy Dodd character in The Master.
 Peggy has been used independently since the eighteenth century, later combined with other names such as Peggy Sue, made famous by the Buddy Holly song and the film Peggy Sue Got Married.
 Some notable namesakes who have gone by Peggy include jazz singer Peggy Lee (born Norma), art patron Guggenheim (born Marguerite), skater Fleming, and author/speechwriter Noonan (born Margaret).
 It's not likely that Peggy will ever regain the 31st position it held in 1937, but we can see it coming into somewhat wider use.
