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.

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.

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.

Gus is a homey grandpa nickname name that can work as a short form for any of the above or stand on its own as a cutting-edge replacement for Max and Jake--though it was off the Top 1000 from 1978 until 2016, when it squeaked in at Number 999.

Mark has the rare appeal of a strong, sleek name with a minimalist modern feel and ancient roots. The name Mark is taken from the Roman god of war Mars, also the namesake of the planet.

Paul is an ancient name for boys -- popular in Roman and medieval times -- that's not very fashionable now, which can work in its favor, scarcity balancing simplicity.

Sally is a cheerful, fresh-faced girl-next-door name that was originally a nickname for Sarah, but has long been used independently. Sally was popular in the eighteenth century and then again from the 1920s to the 1960s--it was just outside the Top 50 around 1940. Though it hasn't been heard as a baby name for decades, we can see Sally bouncing back, especially after her exposure as young Ms. Draper on Mad Men--the Nameberries rank it at Number 621, and it's a Top 100 name in Sweden.

Sweet and spirited, kindly and handsome, posh and approachable, Toby is a versatile nickname, popular in the UK as a stand-alone choice, but familiar in the Netherlands and New Zealand too. In the US, it had its heyday in the 70s but has since been outranked by long form Tobias.

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

A cool, windswept, surfer babe-magnet in 1965, a nice dad -- or even granddad -- today.

We've seen Ray regain his cool, but could this country/cowboy name epitomized by Roy Rogers (born Leonard Slye), Acuff, and Clark, do the same?

Although it has come to sound Irish, Dennis is one of the most widely-used French names (St. Denis is the patron saint of France) and harks back even further to Dionysius, the Greek god of wine and debauchery. It was introduced to England by the Normans.

Karen, a once sweet Danish import, was so popular during the baby boom (Karen was Number 3 in 1960) that it's become a mem in recent years, representing a hostile white woman—one who usually wants to speak with the manager.

Despite all the "hanging," "dangling," and "pregnant" chad jokes of the 2000 election, this saint's name and remnant of the Brad-Tad era didn't get a boost in popularity. But Chad still holds some surfer-boy appeal for a number of modern parents.

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.

When Harrison is too much, but Harry isn't enough, try this stylish surname name with a touch of British flair. It briefly reentered the US Top 1000 for the first time since 1988 in 2016, but has since dropped just below the radar again.

Probably due to its nursery rhyme association, Jill has the perpetual air of a rosy-cheeked tot -- even though it is one of the oldest names on the roster, a medieval variation on the Roman Julia. The pairing of Jack and Jill to connote a generic boy and girl goes back at least to the fifteenth century. But can knowing Jill's history keep it from sounding like a cute mid-twentieth century invention? There may be some possibility of Jill making it back up the hill.

Combine the popularity of Betty White and Mad Men's glamorous Betty Draper Francis, with the residual sweetness of Ugly Betty's Betty Suarez, and the result is an impending return of the name. It's got presidential cred via Betty Ford and feminist history through Betty Friedan.

When Gary cracked the Top 10 in 1950, it was one of the first nonclassic boys’ names to do so, largely due to Gary (born Frank) Cooper, who was renamed after Gary, Indiana, his agent's hometown. Now, a 65 years later, Gary isn't particularly high in the charts, and has lost any glitter it had. May we suggest the fuller name Gareth?

Curtis is an attractive if somewhat dated surname name that has been borne by several significant musicians and athletes--think Curtis Mayfield, Curtis James Jackson III--aka 50 Cent, and also director Curtis Hanson.
