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.

With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.

Guinevere was the name of the beautiful but ill-fated queen of Camelot, for so many years eclipsed by its modern Cornish form Jennifer. Today, Guinevere could be a cool possibility for adventurous parents intrigued by this richly evocative and romantic choice.

Clement, the name of fourteen popes and several saints, has a pleasantly, positive, slightly antiquated feel, like the phrase "clement weather."

The Dorians were an ancient Greek tribe, one of the three major pre-Spartan tribes. It literally means "of Doris," a Greek district, or "of Doros," referring to the son of Helen of Sparta. Dorian derives from the Greek doron, meaning "gift," along with related names such as Dorothy and Dora.

Beatrix has a solid history of its own apart from Beatrice, with that final x adding a playful, animated note to the name's imposing history and stately vibe.

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.

Xavier originated is use as a given name after Saint Francis Xavier, cofounder of the Jesuit order, who got his name from the Spanish-Basque village where he was born. His birthplace was Javier, the name of which was derived from the Basque place name Etxeberria, meaning "castle" or "new house."

Delphine is a sleek, chic French name with two nature associations — the dolphin and the delphinium, a bluebell-like flower, a well as a link to the ancient city of Delphi, which the Greeks believed to be the womb of the earth. All of these derive from the Greek word delphus "womb".

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name. In fact, it's already a fairly popular choice on Nameberry and a solid presence on the England and Wales charts, where it's featured in the latter half since the 90s.

In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, giving this name a dark yet mystical feel. While some may associate too strongly with the word nix (meaning "nothing", "refuse" or "put an end to"), or to the make-up brand Nyx, it was nevertheless chosen for 64 girls (and 26 boys) in the US in a recent year.

Quirky in the way that all Q names are quirky, Quincy was once a buttoned-up, patrician New England name, an image countered in recent years by the talented and ultracool musician Quincy Jones (middle name: Delight; nickname: Q).

Ernest is one of those sober, so-far-out-they're-beginning-to-be-reconsidered Great Uncle names. Ernest recently received a big style boost when Britain's Princess Eugenie chose it for her second son.

If Flora and Florence have returned full force, Florian, with its trendy Latinate ending, could also have a chance. Popular in Germany, Austria, Switzerland, Poland, and France, St Florian was the venerated patron saint of those in danger from water and the patron saint of firefighters.

Octavia began as the Latin, then Victorian name for an eighth child. While there aren't many eighth children anymore, this ancient Roman name has real possibilities as a substitute for the overused Olivia; recommended for its combination of classical and musical overtones. It was chosen for his daughter by Kevin Sorbo.

A "modernization" of Leonora that has suddenly come back on the radar along with the many other Leo names--both male and female. With literary cred via a famous eponymous poem by Edgar Allan Poe (and also in his even more famous The Raven,) Lenore was steadily in the top half of the popularity list until the mid-fifties, falling off in 1973. Cameron Diaz played a Lenore in The Green Hornet.

Once a powerful Roman clan name, Cecil has lost much of its potency over the years, though it retains a strong presence in the sports and jazz worlds. Past bearers include film giant Cecil B. DeMille, poet Cecil Day Lewis, father of Daniel, and photographer Cecil Beaton. Fictional Cecils appear in Oscar Wilde's play, Lady Windemere's Fan, E. M. Foster's A Room With a View and the film Lee Daniel's The Butler.

Cosima, the kind of elegant and unusual name the British upper classes love to use for their daughters, is given to a handful of baby girls in the US after being chosen by two high-profile celebs in the same month; cool couple Sofia Coppola and Thomas Mars as well as supermodel Claudia Schiffer. It was used earlier by celebrity chef Nigella Lawson, while the male form, Cosimo, was given to the son of Marissa Ribisi and Beck.

Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too.

Immortal through its association with the ancient Caesar (it was his clan name), Julius may still lag behind Julian, but is definitely starting to make a comeback, and in fact feels more cutting edge, in line with the current trend for Latin -us endings.
