Effie is the old-fashioned short form for Euphemia. It shares a vintage charm with Hattie and Letty although is much rarer than either. Effie is a character in The Hunger Games and Sisterhood of the Traveling Pants.

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.

Cato conjures up images of ancient Roman statesmen and southern antebellum retainers; it could have revival potential, with its 'O' ending and the current interest in the names of Greek and Roman antiquity.

Though ancient, Marcus now sounds more current than Mark, in tune with today's trend towards us-ending Latinate names.

One of the new bird names, like Lark and Wren, this one's associated with the billing and cooing sounds of love. Soft and gentle, Dove also has the admirable association with peace.

A quaint and quirky flower name, until recently considered a bit too prim for most American classrooms but brought back to life in recent years by the attractive character of Primrose "Prim" Everdeen in the Hunger Games series. In the Top 300 girl names in England and Wales and on Nameberry, Primrose remains rare in the US, but is made more accessible by a raft of sweet nickname options, including Rosie and Posy.

Though it sounds like a chopped-off variation of Olivia, which means olive, the distinctively attractive Livia has been an independent name since the days of the ancient Romans, when it belonged to Livia Drusilla—the powerful wife of the Emperor Augustus—and is still commonly heard in modern Italy.

Caesar, the name of the greatest Roman of them all, is rarely used outside Latino families, where the Cesar spelling is preferred —as in activist Chavez and Dog Whisperer Millan. Its original meaning is debated — either "long-haired", "blue-gray" (as in eyes), or "cut" (because Julius Caesar was supposedly born by cesarian section) — it came to be the title to denote all Roman emperors and it is from the name Caesar that many other European royal titles are derived, including Kaiser and Tsar.

Cressida is a pretty mythological and Shakespearean heroine name much better known in Britain than it is in the US. Given to just 7 girls in a recent year, it shares the cool golden meaning of Aurelia, Orla, and Goldie, and offers cute Cassie- alternative nickname Cressie, along with Ida and Sid too.

The great American novelist sets this above many other surnames (and nature names, for that matter), but it's still an imposing and adventurous choice. Do nicknames Hawk or Thorne make it more approachable? How about Hank or Hal instead?

One of the hot two-syllable T names of the nineties (along with Tyler, Trevor, and Taylor), and well represented on soap operas; Tanner is still widely used, but its popularity is declining.

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna.

Mitchell has had something of a roller coaster ride, showing some panache in the forties and fifties, when it was seen as a sharper alternative to Michael with its cool Mitch nickname, slipping a bit, then resurfacing in the 90s when it reached as high as Number 71. Mitchell Pritchett is one of the leading characters on the TV sitcom Modern Family.

Brutus is the quintessential brute--far too close to the word brutal. And any child with this name would spend much of his life hearing "Et tu."

Seneca's distinguished heritage as the name of the ancient Roman philosopher-playwright who tutored Nero, and of an Iroquois tribe makes this an interesting choice for either sex.

A short and sweet Spanish and Portuguese name, meaning "sun". Sol has been used on its own for centuries (it belongs to one of the daughters in the 10th-11th century Spanish epic poem "El Cantar de mio Cid"), and it is also found as a short form of the Marian names María del Sol and María de la Soledad, and of the related names Marisol and Soledad. A famous bearer is Argentine TV presenter (María) Sol Perez.

Dalton is a name with multi-faceted appeal. Many are attracted to the name's resemblance to other two-syllable n-ending favorites: Colton, Holden, and cousins. Others see it as a trendy Western name, recalling the legendary Dalton Brothers gang. It also has something of an upscale, preppy feel connected to the exclusive New York private school.

He was the original Roman, Remus's twin and a founder of Rome. But parents attracted to this name are advised to read the legend first. Romulus does have some less than savory characteristics, including killing his twin brother and making Rome in his own image, and is later deified as Quinnius. Romy and Quinn might make good twin names.

Forget the oil. It's one of the twins that make up the constellation Gemini, and a mythological name on the cutting-edge of fashion; used by Metallica's James Hetfield.

Portia is a perfect role-model name, relating to Shakespeare's brilliant and spirited lawyer in The Merchant of Venice, and is now also a Hunger Games name .
