Sebastian is an ancient martyr's name turned literary, and Little Mermaid hero—think Sebastian the Crab—that's more popular than ever, as a classic-yet-unconventional compatriot for fellow British favorites T Theodore and Oliver.

Remy is one of the hottest names today for both boys and girls, sometimes spelled Remi. . It entered the popularity list in 2009 and has quickly become one of the fastest-rising names on the list.

Dominic comes from the Latin name Dominicus and is common in the Roman-Catholic community. In the past it has been given to boys born on Sunday—the word "Sunday" in languages including Spanish and French shares Dominic’s roots. In use in the English-speaking world since medieval times, its most famous bearer was St. Dominic, founder of the Dominican order of monks in the thirteenth century.

Victor is one of the earliest Christian names, borne (as Vittorio) by several saints and popes, symbolizing Christ's victory over death. It has been quietly in the Top 200 since 1880, but just recently has taken on a cool edge by fashionable parents in London and seems ripe for a similar reevaluation here too.

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.

Griffin is one of the newer and most appealing of the two-syllable Celtic surnames. In English, griffin is the name of a mythological creature, half eagle, half lion. It re-entered the list in 1983 after an absence of 75+ years.

Lawrence has survived from Roman times, when Laurentium was a city noted for its laurel trees (the laurel is a symbol of wisdom and achievement). It was in the Top 50 from the 1890s through the 1950s and the Top 100 for decades longer, always among the most popular boys' names starting with L, but Lawrence is now used less for babies than Landon or Lorenzo.

Though Jules hasn't been on the US popularity list in fifty years, it is a current hit in its native France—where it's currently in the Top 10—and we can definitely see it making a comeback here, being far more romantic than, say, Jim.

Substantial, strong, and enduring, Anthony has remained a perennially popular name over the last century. With just a hint of playfulness and just a touch of clunky-coolness, Anthony is a versatile choice that seems comfortable anywhere.

Roman is an ancient name trending in a major way. A surprise hit name of recent years, Roman now ranks in the Top 100 not only in the US but throughout the English-speaking world, and is rising in other European countries as well.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.

Since Aurelius was given the supermodel seal of approval by Elle Macpherson, it has joined Augustus as an ancient Roman name that feels usable today. Slightly mystical and magical with a golden hue, Aurelius is grounded by its similarity to rising stars Aurora, Aurelia, and Atticus.

Martin is one of those names like Arthur and Vincent and George that is in the process of throwing off its balding middle-aged image to start sounding possible again, used in full without the dated Marty nickname.

Valentine is an attractive Shakespearean name with romantic associations, but those very ties to the saint and the sentimental holiday have sent it into a decline, one which we think may be about to turn around.

Since this was the name chosen by the late Roman Catholic pope in 2013, Francis has come into the spotlight.

Cornelius, the New Testament name of a third century Pope and saint, is one of those venerable Latin names on the edge of consideration, despite the corny nickname alert.

Lucifer is the name of the archangel cast into hell and while theologians disagree on whether he and Satan are separate beings, it long been on the list of forbidden names for religious and non-religious parents alike. With connotations of hell and devilry so strongly attached to it, the name is officially banned in some places, including New Zealand.

Derived from the Latin word aemulus, Emil is a name with international appeal. Concise and sturdy but with the gentle Em sound, Emil is popular across Europe, from Azerbaijan to Finland, from Germany to Norway, and Denmark. Alternative spelling Emile also ranks highly in Belgium and Canada.

Parents who like Ben and Benjamin but find those forms too popular sometimes consider Benedict as a more distinctive choice. Unlike the Old Testament Benjamin, Benedict is the name of the saint who formed the Benedictine Order and of fifteen popes,including a recent one.

In the past, Orson has felt like a one-person moniker, tied to film director Orson Welles, who dropped his given name of George in favor of his more distinctive middle. While the Citizen Kane creator seemed to own the name during his lifetime, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set too -- both Paz Vega and Lauren Ambrose have little Orsons.
