Stately Gaius (pronounced GUY-us) was in the name of many ancient Romans, including Julius Caesar. Little-used before the year 2000, it now feels like a fresh possibility in the revival of Latin boys' names like Atticus and Cassius. Caius and derivatives like Caio come from the same root, and in ancient Roman times Caius was probably pronounced as Gaius. You could also see Gaius as a male version of the earth-goddess name Gaia.

Septimus is one of the more dashing of the birth-order Latin number names that were revived by the Victorians. So even if you don't anticipate son number 7, you might be bold enough to consider this relic, certainly preferable to sixth-son name Sextus.

The association with the infamous Nero, the fiddling Roman emperor, would be unavoidable. But there was also the detective Nero Wolfe, hero of many mystery stories.

Valerius is an ancient Roman family name turned first name. While Valerius is more familiar as its derivatives Valerie and Valerian, the rise of Roman names ending in S for boys may inspire a revival of this strong choice.

Although often connected to the men's magazine title, Maxim is a chic and powerful name for a little boy. It's proving moderately popular too, having been in the Top 1000 in the US since the year 2000.

Deriving from the Roman cognomen Vivianus, Vivian was originally a masculine name, with Vivien being a feminine soundalike coined by Alfred Lord Tennyson for the Lady of the Lake in his famous poetic adaptation of the legend of King Arthur. It has since become a much more popular choice for girls in the US, but retains a refined British charm which sees it cropping up occasionally for boys in the Telegraph birth announcements.

Maro is an ancient saints' name -- he was an Italian follower of St. Flavia and was martyred -- rarely used in modern life. The name Maro may stem from the Roman Marcellus, related to Mars, the god of war, or it may be a feminine form of Maria, connected with Mario. Maro is also a Japanese name meaning "myself."

The only version that works for boys anymore is the Latinate Hilario or Ilario. Better to look to Felix for a happy-meaning name.

Branch is an attractive name with associations both with trees and with branching out into brave new worlds. Baseball's Branch (born Wesley, with Branch as his middle name) Rickey broke the color barrier by hiring Jackie Robinson for the Dodgers. Like Leaf, Branch makes a nice, not-so-obvious, addition to the tree category.

Popular in the Hispanic world and used in honor of Saint Augustine, Agustin is an anglicized form of the Spanish Agustín. It peaked at Number 561 in 2001 in the US charts and has since dropped on and off of the list again. Given to around 210 boys in a recent year, Agustin also ranks highly in Chile and Uruguay.

The final o adds a macho touch.

Cesar is the sleeker version of Caesar, as in emperor Julius, used in the US most frequently by Hispanic parents who put the emphasis on the second syllable. With ancient Roman names back in vogue, Cesar might become more popular.

After Leo, this is one of the most usable names in the zodiac: part ancient, part new-age, part high-tech. In the night sky, the constellation Gemini is present all year round in both hemispheres. It has been associated with twins since ancient times, and its two brightest stars are named Castor and Pollux after the twins of Greek mythology. It also has STEM connections: Project Gemini was a NASA spaceflight program before Apollo.

Vince is not a short form that often stands alone on the birth certificate, the way Jack or even Joe does, but it has certain credibility as the name always used for football great Vince Lombardi. And as a diminutive for Vincent, it's a far sight better than Vinnie or Vinny or even Vin.

The revival of long-dormant Roman names would put this back in the lexicon if it wasn't so connected to a telecommunications network.

Adventurous parents are starting to look back to names of ancient gods like Mercury, Zeus, and Apollo. This one is also a planet and a metallic element, and has a friendly nickname, Merc. The Roman god Mercury, which derives from the Latin words for trade or wages, is the patron of tradesmen and travelers and the fastest-moving planet in the solar system. Mercury is the planet associated with the sign of Virgo, so this is one of the prime names for Virgo babies.

Joyful-sounding name that makes a really original option.

Old World Italian name that might become fashionable in a so-far-out-it's-in way, like Enzo and Rocco. Main recommendation: It's among the rare boy names that mean life.

Woodsy name referring to the Roman tree god Silvanus.

Pacific is an adventurous kind of place-name, with the added bonus of the association with peace.
