Bartholomew is an apostle's name that's been out of favor for centuries but might appeal again to the parent in search of an old but rare choice. The challenge could be to avoid the Simpson-ish nickname. That character, by the way, has the full name of Bartholomew JoJo Simpson, and creator Matt Groening came up with Bart as an--uh oh--anagram for brat. Two old alternate nicknames are Barty and Tolly.
 Ben Jonson's 1614 comedy Bartholomew Fair is set in London on St. Bartholomew's Day. Charles Dickens used the name in Bleak House, and, more recently, Bartholomew Cubbins is the protagonist of the Dr. Seuss books The 500 Hats of Bartholomew Cubbins and Bartholomew and the Oobleck

Brantley is one of several English surnames that was new to the tops in 2009. A possible-probable inspiration is the country rock singer Brantley Gilbert.

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. An alternative commonly cited meaning that modern parents might prefer is "proclaimer of peace". The traditional Polish spelling of the name is Kazimir.

Casimir

For a generation, this name will always be linked to 1990s hit TV series Friends. Whether this is a positive or a negative will depend on your fondness for the show, and character Chandler Bing, but this name deserves consideration beyond these connotations: Chandler is a fresh take on the professional surname names.

Connelly is an open, inviting, and rarely used Irish surname that can make a perfect alternative to the overused Connor or Colin for a boy.

Dashiell, though missing from many other name sources, is among the hottest new names, chosen by such celebs as Cate Blanchett and author Helen (Bridget Jones) Fielding. With its great dash and panache, Dashiell is associated with detective writer Dashiell Hammett (born Samuel, as in Sam Spade, Dashiell being his mother's maiden name). Alice Cooper was ahead of the game: He named his son Dashiell in 1985.
 For those still confused about the pronunciation, it's kind of similar to castle or bashful. And anyone can pronounce Dash, which is such a dashing nickname.

Dashiell

Dimitri is a Slavic variation of the Russian Dmitriy, a name that comes from the Greek Demetrius. Demetrius was derived from Demeter, the name of the Greek goddess of fertility and farming. Among the possible spelling variations are Dmitri, Dmitrii, Dmitriy, and Dmitry.
 
Dimitri is a worldly, artistic, and attractive name. It has been on and off the bottom of the US Top 1000 list in recent years. Dmitri is another possibility that may prove more challenging for some English speakers to pronounce, although it was the spelling Mila Kunis and Ashton Kutcher chose for their son.

Dimitri

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.
 
Dorian was introduced as a first name by Oscar Wilde in his 1890 novel, The Picture of Dorian Gray, the story of a narcissistic character who retains his youthful good looks while his portrait in the attic ages grotesquely. Despite this negative reference, Dorian's attributes have kept it consistently on the boys' list since the 1960s.
 Dorian also has a musical reference, being the name of one of the modes.
 Actor Dorian Harewood has been a familiar presence in movies and on TV.
 Rhythmic and unusual, Dorian makes a distinctive choice.

A major figure in the Old Testament, Enoch was the son of Jared, the father of Methuselah, and the great-grandfather of Noah whose Book of Enoch provides a focal point for ancient Jewish mysticism. Another Enoch was the son of Cain. "Enoch Arden" is a famous poem by Alfred, Lord Tennyson. On the negative side, British politician Enoch Powell gave the infamously racist Rivers of Blood anti-immigration speech, taking the name out of consideration for many parents in the UK.

Enoch

It derives from Mac Aodhagáin, meaning "son (or descendant) of Aodhagán," a diminutive of the Irish name Aodh--pronounced Aye.
 The related name Egan is another recommended possibility.

Lennox is an aristocratic and powerful Scottish surname name made truly special by that final x. The worldwide fame of British boxer--World and Olympic champion--Lennox Claudius Lewis brought the name into the spotlight as a first name, while as a last it's tied to Eurythmics singer Annie L.
 The Thane of Lennox appears in Macbeth, Mary Lennox is in The Secret Garden and there are two Agatha Christie characters with the name.
 Lenox is another accepted spelling.

Lucian is a sleeker, more sophisticated version of Lucius that is climbing in tandem with other Lu-starting names.
 Historically, the name was made famous by the ancient Greek satirist Lucian of Samosata--sometimes considered the father of science fiction-- and by the third century St. Lucian.
 A modern bearer was Berlin-born British painter Lucian Freud, grandson of Sigmund. In pop culture, Lucian the Lycan is a werewolf in the Underworld movies. 
 Lucian was picked by Indie actor Steve Buscemi. Lucien is the French version. The attractive Italian form is Luciano, as in Pavarotti.

Marcel, despite distinguished namesakes including Proust and Duchamp, suffers from a terminal headwaiter image in this country. But along with its sister name Marcella and French variation (and Jolie-Pitt pick) Marcheline, Marcel may be on the brink of a style renaissance.
 French Oscar winner Marion Cotillard named her son Marcel in 2011.
 Fans of the sitcom Friends will remember Marcel as the name of Ross's pet monkey.

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.
 Septimus was popularized by the Roman Emperor Septimus Severus, a patron of arts and letters. There was a Septimus in Wilkie Collins's The Moonstone, in Dickens's The Mystery of Edwin Drood, and in Trollope's Barchester novels. Probably it is most familiar to modern readers as one of the principal characters in Virginia Woolf's Mrs. Dalloway, and as Harry Potter wizard, Septimus Weasley. There is also Septimus Heap, a series of bestselling fantasy novels by Angie Sage.

Septimus

No longer a one-person name, as a number of parents have been inspired by basketball great Shaquille O'Neal to adopt it for their own future athletes.

Sullivan is a jaunty Celtic three-syllable name, with a real twinkle in its eye. It was immortalized in the 1930s classic film Sullivan's Travels and was chosen for one of Patrick Dempsey's twin boys. Nickname Sully is equally jaunty.
 The third most common surname in Ireland, Sullivan's heritage dates back to the third century. Countless distinguished surnamed Sullivans include Sir Arthur, half of composing team Gilbert & Sullivan, Helen Keller's teacher Annie, Chicago architect Louis, early boxer John L. and dour columnist/TV emcee Ed.
 Other celebs with boys named Sullivan: singer Tom Waits and actor James Marsters. Heroic pilot Chesley Sullenberger is known as Sully, and a featured character in Pixar's Monsters, Inc. and Monsters University was Sullivan.

Sullivan

The double 'e' gives this Celtic surname a genial sound. It derives from an old Irish name &mdash; Suibhne (SHEEV-ne) that was borne by several early saints and kings, including, unfortunately, one known as Mad Sweeney who spent his life living in trees and composing nature poetry. Another possible drawback is the association with Sweeney Todd, the bloodthirsty butcher of Sondheim stage-musical fame.
 But if you can put all that aside, Sweeney makes a cheery choice.

Sweeney

Honor and bravery are certainly virtues any parent would want to encourage, and this word itself is obscure enough that it manages to sound like a real name.


Valor

While this is usually thought of as a girls' name because of the Bond Girl connection, its sound is masculine and there's no reason it couldn't work for boys.

If you're looking for a name that's light and breezy, this could be it. A name from mythology: Zephyrus/Zephyr was the Greek god of the west wind-- with many European variations, it's a name that's frequently seen in computer and video games, is a character in the children's book Silverwing, and appears in the Babar books--as a monkey.
 Robby Benson and Karla De Vito named their son Zephyr in 1992, and Zephyr Benson is now an actor himself. More recently it was chosen by tech entrepreneur Sean Parker for his baby boy.
