Boy Names That End in S

Leonidas is an ancient name that has started rising again along with centuries-old names such as Augustus and Cato. The original Leonidas was the most famous of Sparta's warriors, sacrificing his life at the Battle of Thermopylae; there is also a saint Leonidas.

Gwyneth Paltrow and Chris Martin's choice of this white-bearded Old Testament name helped bring it into the modern age, along with brethren Elijah, Isaiah and Isaac. User-friendly nicknames include Moe and Mose.

Parents who have tired of Sean are now contemplating Seamus, the Irish form of James, which has a lot more substance and verve.

One of those place and surname names that hasn't be used much as a first name yet -- but could soon. You could think of it as a fun, one-syllable twist on Amos. Ames is also notable as a surname that comes from a female name, Amys or Amice, ultimately deriving from the Latin amicus, "friend".

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.

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.

Erasmus has long retained the image of the bearded and bespectacled Dutch philosopher, but could be one that the audacious baby namer just might dare to dust off.

Relaxed, laid-back cowboy name with broad appeal and more staying power than you might guess: Dallas has ranked among the Top 1000 boy names in the US since records began in 1880.

Classical and Shakespearean name that may appeal if you like your names long, flowing and multicultural.

An appealing Irish placename with a unisex feel, Ennis would be a fresh alternative to Dennis and Ellis. It's little-used for boys and even rarer for girls, but since Kirsten Dunst and Jesse Plemons used it for their son, it could be one to watch.

Davis is a fresh way to say David. Some sources define it as "son of David," but we see it as a surname spin on the original. While David is an everyman name, Davis has some creative edge -- and still gets you to the classic guy nickname Dave.

Smooth and sleek one-syllable name, sometimes suggested for Sagittarius boys.

Octavius, which was at one time used for the eighth child in a family, has the worn leather patina of all the ancient Roman names now up for reconsideration. As a Roman family name, it derives from the uncommon forename Octavus, which designated an eighth son.

It’s been more than three decades since Ferris Bueller took his famous day off in the cult classic 1986 teen comedy movie, but we think the time for this name could and should be now! Especially with the recent rise of the hero's girlfriend, Sloane, up the baby name rankings. Half preppy, half rugged, it boasts that stylish S ending and has a cozy, retro feel.

The two X's may be a challenge for even the most intrepid baby namer. Xerxes was the name of two early kings of Persia and the Handel opera Serse or Xerxes is loosely based on Xerxes I.

One of those names that most Americans find just too too tea-sippingly British to consider; its meaning has led to occasional use for Capricorn boys.

When the King was alive, and for years afterwards, few people (except Declan McManus who became Elvis Costello) dared use his singular name, but now it's very much up for grabs.

More unusual than Justin, less word-like than Justice, this New Testament name could make an intriguing choice. After being off the popularity lists from 1904 to 1993, it is now being used in steady numbers.

A place name with so much history, from Ancient Egypt, where so many pyramids were built, to the US blues southern city. The name also has a great meaning. Although it's being given to babies of both genders, Memphis (unlike most place names) is much more common for boys than girls.
