Ada is one of the classic <a href="https://nameberry.com/">baby names</a> for girls that is suddenly super stylish again. A favorite at the end of the nineteenth century, Ada is an alternative to the over-popular Ava. Ada is also part of the trend toward simple, old-fashioned names beginning with a vowel, like Ivy and Ella.
 
Ada is derived from the German name Adelaide, which came from the ancient name Adalheidis. The root, adal, is a Germanic word meaning "noble." Ada can also be considered a variation of the biblical name Adah, pronounced AH-da, one of the first <a href="https://nameberry.com/girls-names">girls’ names</a> mentioned in the Book of Genesis. 
 
A worthy namesake is Ada Lovelace, mathematician daughter of the poet Lord Byron, who worked with Charles Babbage on the forerunners to the calculator and the computer. In his poem Childe Harold's Pilgrimage, Byron addresses her as "Ada! sole daughter of my house and heart."
 
Ada has a number of fictional references as well, appearing in Dickens's Bleak House and Nabokov's 1969 novel Ada; additional characters with the name were portrayed by Holly Hunter in The Piano and Nicole Kidman in Cold Mountain.
 
Ada returned to the Top 1000 in 2004, after being off since 1992; by contrast, Ada was a Top 100 name in the 1880s.
 
The Turkish name Ada means "island" and is unrelated — though it makes an excellent option for parents looking for a name spanning two cultures.

In its three most popular spellings -- Alan along with Allen and Allan -- this midcentury favorite has tended to skew older. It was a Top 100 name from 1938 to 1971, peaking at Number 40 in 1951. Alan has had leading roles on recent TV, in shows like Two and a Half Men, 24 and Boston Legal.
 Current bearers include Alan Alda, Alan Cummings, and writers Alan Bennett and Alan Ayckbourn.
Alan is a venerable Celtic name, first used in England in the Middle Ages. We like the Welsh spelling Alun.

Albert has acquired a new gloss as one of the top <a href="https://nameberry.com/list/341/royal-names-for-boys">royal baby boy names</a>, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer). 

Albert became popular in Britain following the 1840 marriage of Queen Victoria to the German Prince Albert and remained in vogue for 80 years. In the US, it's been on a downward slide for a century, though it's always ranked in the US Top 1000 and is a Top 100 name in England and Denmark.

Along with such stalwarts as Walter and George, it could now make a distinctive yet classic choice. Enlivening nickname Bertie is popular on its own in the UK.

Albert

Archimedes of Syracuse was a famous Ancient Greek thinker, especially in the fields of mathematics and sciences. He made important contributions to geometry and calculus. His name was a perfect choice, meaning "master planner" or "master thinker". This off-the-beaten-track choice of name was given to 10 little boys in the US in 2014. We recommend it to more parents, especially those with a penchant for all things ancient or mathematical.

As modern as it sounds, Blaise is an ancient Christian martyr name. In Arthurian legend, Blaise is the name of Merlin the Magician's secretary. Its relation to the word and name Blaze gives it a fiery feel. Amanda Beard named her baby boy Blaise Ray.
 Saint Blaise, an Armenian bishop, is the patron saint of wild animals and those with sore throats. Blaise Pascal was the seventeenth century French mathematician-physicist-inventor-writer-philosopher among whose many accomplishments was the invention of the calculator. And in the modern world, Blaise Zambini is a minor character in the Harry Potter franchise.

This no-nonsense German variation of Charles is strong and sturdy. A top choice throughout the 20th century, Carl is now verging on falling off the charts.

Carl

Charles derives from the Germanic name Karl, meaning "man" or "freeman", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries. 
 
The word for "king" in several languages, including Slavic, Russian, and Polish, came from Charles. And, of course, Charles III is the current king of Great Britain.
 
Charles is a longtime traditional favorite that was in the Top 10 until the 1960s. Though not as popular as it once was, it's still a widely used name. 
 
The most fashionable form of Charles today is Charlie, used almost equally for girls and boys. And of course, Charlie or Charley is still used as a short form for Charles, along with the old school Chuck and new school Chas/Chaz.
 
Lately, Charles has been resuscitated by many celeb parents, from Jodie Foster to Russell Crowe, honoring a distinguished history dating back to the emperor Charlemagne—the original Charles the Great. 
 
Charles has been so well used for so long that it is virtually faceless—it can conjure up anyone from Dickens to Chaplin to Bronson. It has been an elegant royal name—designating both Bonnie Prince Charlie, leader of a 1745 rebellion, and the present king, as well as previous kings of France, Spain, England, Portugal, and Hungary. 
 
Among the well used international versions of Charles: Carl, Carlo, Carlos, Karel, Xarles, Charlot, and Siarl.

David is an enduring worldwide classic, used from ancient times to the present day.
 David is derived from the Hebrew name Dawid, believed to come from the root dôwd, meaning “beloved”. The first famous David was the Old Testament second king of Israel: the shepherd boy who killed the giant Goliath, and later a warrior, poet, and powerful leader, wise but humanly fallible. He is an important figure in Judaism, Islam and Christianity, and later inspired many works of art, including Michelangelo’s colossal sculpture.
 Since then, there have been countless Davids of note in history, literature, and popular culture, including the patron saint of Wales — a translation of the Welsh name Dewi — two kings of Scotland. Then there’s Copperfield, Crockett, Bowie, Beckham, Letterman, Grohl, and many more. Celebrities who have chosen it for their sons include Jennifer Hudson, Bar Refaeli, and J.K. Rowling.
 In its international forms, David is steadily popular around the world, and ranks in the Top 10 names in Brazil, Austria, Armenia, Croatia, Bosnia and Herzegovina, and Israel.
 In the USA, David has never been out of the Top 40 boy names, but was at peak popularity in the mid-twentieth century, ranking in the Top 10 from 1936-1992. This means that, although it’s still given to thousands of boys each year, it has an “older man” feel to it. It ranks highest in states with a large Jewish population, and is still a Top 10 name in New York.
 After Daniel, David is the second most popular <a href="https://nameberry.com/search/boys-names/d">boy name starting with D</a>. Although fading a little in popularity, it remains a serious-yet-friendly classic with deep roots.
 If you’re looking to update David, perhaps as an honor name, the freshest alternatives are surnames deriving from David, including Dawes, Dawson, and Davies. You could also try an international variation, like Welsh Dai or Finnish Taavi.

David

Long a nickname for all the Em-names, as well as an annual award, Emmy is now being given on its own, as are soundalikes Emme and Emmi. Might be too identified with the TV awards--though that doesn't seem to have hurt Oscar or Tony. We think Emmy is a little too cutesey, and is probably best kept as a nickname for something that ages a little better.

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.
 Isaac evolved from the name Yitzchaq, derived from the Hebrew word tzachaq, meaning "to laugh." In the Old Testament, Isaac was the long-awaited son of the elderly Sarah and 100-year-old Abraham, so old that their news provoked laughter, giving the name its meaning. Isaac is used as a given name among Jews, Christians, and Muslims alike.
 
A baby given this name can point to many distinguished namesakes, including Isaacs (and Izaaks) Newton, Walton, Bashevis Singer, Asimov, Stern, Hayes, and Hanson.
 
Isaac also boasts the cute nicknames of Izzy — now shared, however, with a bevy of Isabellas — and Ike.

Isaac

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.

Leonhard

Margaret is derived from the French Marguerite, which in turn came from Margarita, the Latin form of the Greek Margarites. Margarites was based on the Old Persian word margārīta, meaning "pearl." 
 
Margaret has been one of the most Christian and royal of <a href="https://nameberry.com/girls-names">female names</a>—attached to the patron saint of women in childbirth and to various queens and princesses in England, Scandinavia, Austria, and the Netherlands, and to the first female prime minister of Great Britain, Margaret Thatcher.
 
Margaret is a rich, classic name used for queens and saints. Margaret was replaced for decades by less starchy forms like Maggie and Meg, but some stylish parents are reviving Margaret in full, attracted by its strong sound and classic status, as an alternative to Elizabeth or Katherine. 
 
Margaret is also an important family name for many people, having ranked near the top through the first half of the 1900s. An extremely well used name since medieval times, Margaret is still considered the Scottish national name.
 
If you're honoring an ancestral Margaret, there are many fresh and new alternatives, from the French Marguerite—very stylish in Paris—to the diminutive Margo (or Margot). In French, Marguerite is another word for daisy, making Daisy another appropriate Margaret short form or honorific, as is Maisie. Other offspring of Margaret include Madge, Marjorie/Margery, Megan, Molly, Polly, Peggy, Greta, and Rita.

The French-accented Pascal was historically used for sons born at Easter, and can make an interesting choice for a boy with Gallic roots arriving around that holiday. 
 Pascal has a number of notable first and last named namesakes, including the philosopher Blaise Pascal, a character in Beauty and the Beast and--for computer freaks--it is also the name of a scientific database.
 Pascoe is an attractive Cornish variation.

Penrose – an ancient locational surname derived from several villages in Cornwall, Wales, and the Welsh border country of England – might work as a first name, although the "Rose" syllable might lead the uninitiated to assume it's a female name. As a middle name, however, it would make for a surprising and distinguished choice. A male Penrose could be called Pen/Penn, Ross or Roe for short.

Penrose

One of the most familiar — if not stereotypical — Gallic names. Pierre was a Top 5 name in France from the 19th century through 1940 and is now on a steady decline in its native land. In the US, Pierre was most common in the 1980s but it has never cracked the Top 300.
 
Australian supermodel Miranda Kerr welcomed a son named Pierre in 2024, which may boost its profile.

Pierre

Pronounced "TAHL-a-mee," this was the name of one of Alexander the Great's generals and several Greco-Egyptian rulers, as well as the name of a famous Greek astronomer. Actress Gretchen Mol brought it into modern times when she chose it for her baby.

In the World War II era, Roger had nothing but the most positive associations, actually used by military personnel to mean 'Received and understood'--or A-OK, and though it is now on extended furlough, it does have a long and distinguished history. Introduced to England after the Norman Conquest of 1066, Roger soon became very popular there, with nicknames Hodge and Dodge, and had a long run later in the U.S, remaining in the Top 100 for 55 years.
 Roger has an impressive list of notable namesakes, both fictional and real. Roger Chillingworth is a major character in Hawthorne's classic The Scarlet Letter, and the name appears in works by Ben Jonson and Anthony Trollope. In sports, there have been Rogers Maris, Clemens, Bannister and Federer, in entertainment actor Roger Moore and Roger Daltry, lead singer of The Who. And of course, many of us remember Roger Ramjet from our childhoods.
 On the dark side, there is the Jolly Roger--a pirate's black flag with skull and crossbones--which a little boy might actually love.

Sophie is the French form of the Greek Sophia, for which it is also commonly used as a nickname. Given Sophia's long standing among the Top 10 girl names in the US, Sophie may feel more popular than it actually is.
 
Sophies are scattered throughout European royal history, including Sophie of Thuringia, Duchess of Brabant, Princess Sophie of Sweden, and in modern times, Sophie, Duchess of Wessex, the wife of Britain's Prince Edward. German-born Catherine the Great was born Sophie of Anhalt-Zerbst, but changed her name to Catherine upon her conversion to Russian Orthodoxy.
 
Sophie is Sophia's cuter, more irreverent near-identical twin. Which do you like better? And do you see them as virtually the same name or very different? While you definitely couldn't name sisters Sophie and Sophia, you may have both on your short list and consider them distinctly separate choices. Sophie is lively and down-to-earth, while Sophia is more sophisticated and buttoned-up. 
 
Sophie was the choice of both Eric Clapton and Luke Perry, as well as of Bette Midler for her now-grown daughter.
 Sophie Zawistowska is the Polish heroine of the iconic William Styron novel Sophie's Choice, played in the 1982 film by Meryl Streep—who would play the mother of a Sophie decades later in Mamma Mia!.

This dignified German form of William belonged to two German Emperors and Kings of Prussia, as well as a host of other important historical figures. These include composer (Wilhelm) Richard Wagner, philosophers Georg Wilhelm Friedrich Hegel and Friedrich Wilhelm Nietzsche, mathematician Gottfried Wilhelm von Leibniz, and physicist Wilhelm Roentgen, who discovered the X-ray. It now sounds rather dated in Germany, however, having dropped out of the Top 20 there in the late 1920s and continuing to decline since.
