This Anglicized form of Bearach or short form of Finbarr was in the Top 200 in the USA for 50 years until the early 80s when it rapidly fell out of favor. Barry has not yet found popularity in the modern era - but that may well change as people rediscover their love of classic figures like musician Barry White, baseballer Barry Bonds or even Barack Obama, whose nickname as a young man was Barry. 

Barry

Bobby is the quintessential mid-century nickname, the name of the son on Mad Men and overused to the point of cliche. Though Robert is still a highly popular choice, most Roberts today are called by their full name or Rob or Robbie rather than Bob or Bobby.

 In the UK the term "bobby" is slang for a policeman.

Bobby

Charles derives from the Germanic name Karl, meaning "man" or "free man", 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.

Donald has been used for centuries in Scotland, where the Macdonald clan is one of the most ancient and where there have been six early Scottish kings by that name. Donald was a Top 20 name throughout most of the early twentieth century. But first there was the quacking Donald Duck, introduced in 1934, to affect its image, and then there was The Donald Trump, leaving it drained of much baby appeal. Trump's surprising run to the presidency didn't save Donald's decline on the baby name charts; it fell 47 spots between 2015 and 2016, from 441 to 488, and is now a less popular name than it's been since records have been kept.
 Aside from Donald Sutherland, most contemporary real and fictive Donalds go by nicknames--as in Donny Osmond, Donnie Wahlberg, Don Rickles and Don Draper. More promising and more authentically Celtic sounding is Donal, which is quite commonly used in Ireland, or surname cousins Donnelly or Donovan.

Frances, a soft and gentle classic last popular a hundred years ago, is trending again. The cool nickname Frankie is one reason for the revival of Frances, adding lightness and sass to a serious name.
Frances is the feminine form of Francis, the English variation of the Latin name Franciscus. Franciscus, meaning "Frenchman," was taken from the Germanic tribe the Franks, which got its name from the francisca, the axe they used in battle. Until the seventeenth century, the spellings Frances and Francis were used interchangeably for both sexes.
 
More recently, Frances started receiving new attention when it was chosen in the early 90s by Kurt Cobain and Courtney Love for their only child. It's been by such stylish parents as Jimmy Fallon and Amanda Peet (who nicknamed her daughter Frankie).
 
Frances was a favorite of the Tudor aristocracy after being given to Henry VII's granddaughter. St. Frances (Mother) Cabrini was the first American citizen to be canonized.
 
Some of the best known pop culture bearers of the name were known by diminutives—the Franny of J.D. Salinger's Franny and Zooey, Francie in A Tree Grows in Brooklyn, Frankie in A Member of the Wedding, Baby in Dirty Dancing, and Gidget in Gidget. Traditional nickname Fran feels a bit bland and Fanny, though possessing some eighteenth century charm, is unusable in Britain and Australia where it is slang for female genitalia.
 Frances is the endearing badger in the childhood favorite Bedtime for Frances and other Frances books.
 Among well known bearers are Frances Perkins, Secretary of Labor in the Roosevelt era; actresses McDormand, Dee, Farmer, and Fisher; journalist Fitzgerald; and writers Burney and Hodgson Burnett.
 Frances was the abandoned first name of Judy Garland, Dinah Shore, and Dale Evans.
 Some attractive foreign versions are the increasingly popular Francesca, Francoise, Franca, Fanya, and Francine.
 Frances began trending upward before Pope Francis was named in 2013, but that helped propel it up further than this somewhat sedate classic name might have gone on its own.

Frances

Glendon

The name of the last Anglo-Saxon king of England before the Norman conquest, and a name that's long been associated with a pipe-smoking, bespectacled grandpa or uncle.
 
After years in style limbo, Harold is slowly making a comeback, possibly boosted by cheerful nicknames like Harry and Hal. Filmmaking couple Greta Gerwig and Noah Baumbach have a son named Harold.

Harold

At the height of the Jennifer craze, many parents were cutting straight to the nickname and putting Jenny on the birth certificate. But now that Jennifer is the mom rather than the daughter, Jenny, which has been somewhat replaced by Jenna, has faded as well. 

Jenny

Wildly popular in the 1960s and '70s, Julie is no longer anywhere near as stylish as the name's longer forms. Try Juliet, Juliana, or even the more grownup Julia.

 Julia and Julie derive from Julius, a Roman family name. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthfu"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

Your friendly next-door neighbor...not your baby. Although Larry was once one of the most popular <a href="https://nameberry.com/search/boys-names/l">boys' names starting with L</a>, that title now belongs to Liam.

Larry

This Welsh surname was taken up as a first in the English-speaking world in the early twentieth century, originally as a nickname for someone gray-haired. The original Welsh name was Llwyd, and pronounced LHOO-eed.  Beau Bridges was christened Lloyd after his actor father.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.
 
The English form of the Roman Lucia, Lucy derives from the Latin word lux, meaning “light.” Once given to girls born at dawn, Lucy is also associated with Saint Lucia, the patron saint of the blind.
 
Lucy has a wide range of namesakes, from the bossy friend in the Peanuts comic, to psychedelic "Lucy in the Sky with Diamonds," to the rash and zany heroine of I Love Lucy. 
 
It is a name with a rich literary history, chosen for the heroines of Charlotte Brontë’s novel Villette, E.M. Forster’s A Room With A View, Jamaica Kincaid’s Lucy, and C. S Lewis’s The Chronicles of Narnia - just to name a few. 
 
Beyond fiction, Lucy Stone was an important American activist, Lucy Worsley is a successful author and historian, and Lucy Lui is an actress who has imparted strength and style to the name.
 
Simple but sophisticated, playful but grounded, it is no wonder Lucy is a popular choice. Given to over 4000 girls in the US each year, it is a classic that doesn’t feel dusty.
 
If you love Lucy, but don’t love its popularity, you could consider one of its many variants. From vintage Lucille, to the musical Lucetta, to the fresh, unexpected Lux; from nickname-y Lou to sleek Luciana, there are plenty of possibilities.

Lucy

Part of the vogue for French-sounding names in the 1920s and 30s, Nadine has been replaced by the Russian sound of Nadia and Natasha. 

Nadine

The classic strong-yet-friendly nickname name, much used for charming movie characters. 

Nick

Peter is derived from the Greek Petros, meaning "rock" or "stone." One of the most important figures in the Christian hagiography is Saint Peter, keeper of the Gates of Heaven. Born Simon bar Jonah, he was given the nickname Peter by Jesus, to signify that he would be the rock on which Christ would build Christianity. Centuries later, there was Peter the Great, the czar who developed Russia as a major European power.
 
For generations, there have been pleasant childhood associations with this classic New Testament name, what with Peter Rabbit, Peter Pan, et al. But as user-friendly as this makes the name, it has a solid, traditional side as well.
 
Never as widely used as some of the more traditional Anglo-Saxon stalwarts, Peter retains an enduring appeal to parents seeking a less-used classic, with those nice childhood associations. Peter also has some interesting derivatives: The Brits like Piers; the Irish, Pierce and Pearse; the Italians, Piero and Pietro; the Spanish, Pedro; the French, Pierre; and the Dutch, Piet.
 
One potential problem: in some parts of the world, "peter" can be a slang term for "penis".

Peter

Ralph has two diametrically different images: there's the suave Ralph Fiennes-type Brit (often pronounced Rafe), and then there's the Jackie Gleason blue-collar, bowling blowhard Ralph Kramden bus driver. It's all in the eye of the beholder, though its hip factor did rise when it was chosen for his son by cool U.K. actor Matthew Macfadyen.
 Ralph is a name that's been around for a thousand years, was in the Top 30 from the 1870s to the 1920s, and just could make a comeback. It's already in the UK Top 100.
 Ralph has a number of notable namesakes, from Ralph Waldo Emerson to Ralph Abernathy to Ralph Lauren. In literature, Ralph is a Shakespearean name, appearing in Henry IV, is a pivotal figure in Henry James's The Portrait of a Lady and Ralph was one of the three main boys in Lord of the Flies. And let's not forget Ralphie in A Christmas Story.
 Or you might prefer the French version--Raoul.

Randall

This ancient royal Scottish name had a brief vogue in midcentury America, but it would be far from a fresh choice for a baby boy now. 

Stuart

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.

Susan

Just like Sam and Ben, Tom could be revived as a simple, well liked name on its own. Tom, just Tom, is one of the <a href="https://nameberry.com/popular-names/france">Top 100 Boy Names in France</a>

Deriving from an English locational surname meaning "white island", Whitney was in rare but regular use for boys in the US until the early 1960s, when actress Whitney Blake popularized it for girls. It received a further big boost on the girls' side in the 1980s, thanks to singer Whitney Houston. Now falling rapidly down the rankings, it could be time to reclaim this one for the boys, if only as a neat way to cool-guy nickname Whit.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular <a href="https://nameberry.com/search/boys-names/w">baby name beginning with W</a> of all time. 
 For 400 years, William has been second only to John as the most popular name in the English-speaking world. And now of course, it's also a newsy name—thanks to Britain's high-profile Prince William.
 William is derived from the Germanic name Wilhelm, composed of the elements wil, "will," and helm, referring to a helmet or protection. The name was introduced to England by William the Conqueror, with William being the Norman variation of the name. In Central and Southern France, it was translated as Guillaume.
 
In terms of short forms, yesterday's Bills and Billys have given way to today's Wills—or Williams, with no diminutive—though a few hip Billys, including Helena Bonham Carter and Tim Burton's, have surfaced recently. 
 But Irish spinoff Liam is the most stylish William nickname and has now superseded William, becoming the most popular boy name in America. Riding the William bandwagon is the Dutch Willem, which comes with the unique nickname Pim.
 
William has long reigned as a royal name in the U.K. There are tons of worthy namesakes called William, including William Shakespeare, Bill Gates and four U.S. presidents.
