Unnamed List

After half a century, this otherwise feasible name has at last started to lose its link to the friendly ghost; it certainly didn't scare model Claudia Schiffer, who chose it for her son, as did Atomic Kitten Jenny Frost. Iconoclastic namer Jason Lee switched genders and called his daughter Casper. Also related to the revived Jasper, Caspar seems headed towards the path to a similar resurgence.

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.

Dylan still feels poetic and romantic after years of popularity. It still ranks highly on the charts, among the top boy names starting with D, so if you choose it, be aware that yours may not be the only Dylan in his class.

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity.

If you like the Finn names and love James Joyce, Finnegan is extremely winning. Will & Grace 's Eric McCormack chose the Finnigan spelling for his son. And of course Finnegan gains you access to the great short form Finn.

Sean and Robin Wright Penn chose this name for their son to honor their friend Dennis Hopper; others might associate it with the painter Edward. Couldn't be more spirited.

Jackson is one of those names that's much more popular than you think, coming in near the top of our annual Playground Analysis, which ranks names by grouping all their spellings together. Last year, nearly 17,000 baby boys were named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 3 boys' name.

The name of the third U.S. President sounds, like Harrison and Jackson, more modern and stylish now than its root name. Used as a first name long before our surname-crazed era, Jefferson was most famously used as a first name by the President of the Confederacy, Jefferson Davis, which may justifiably make you not want to use it. Jefferson is the middle name of another Prez, William Clinton.

Kermit was a Top 500 name until the 1960s, not coincidentally the decade in which Kermit the Frog made it a one-person (well, one-frog) name.

Kingsley is a sophisticated Harry Potter name that entered the US Top 1000 in 2013.

Lewis is the best spelling to choose if you want this pronounced with the S. It was a Top 100 name in the US from 1880 to 1930, reaching Number 30 in 1880 and while it has declined in use, it has remained in the Top 1000 since stats began.

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century and now ranks at its highest point ever, in the Top 50.

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.

Could Philo be the next Milo?

Quinn is an engaging Celtic surname that is still on the rise for girls but beginning to flag for boys. As a female name, Quinn is in the Top 100, used for over 3000 baby girls last year, but toward the bottom of the Top 500 for boys, given to 700 baby boys.

River shares the tranquil feeling of all the water names, and seems to have pretty much escaped its past strong association with River Phoenix and his unfortunate fate. Actor Joaquin Phoenix named his son with actress Rooney Mara after his brother River.

A unique natural-wonder option, conjuring up the beauty of the lake between California and Nevada that has become a popular tourist destination.

See the popularity graph below for the name Theo? It's been heading straight uphill since 2010, when it hopped back onto the Top 1000 after a 60+ year absence.

Truman is an upstanding presidential name that radiates an aura of integrity and moral truth, values any parent would want for a child. It seems definitely headed for a revival.

Walker is both a Waspy surname name—as in the W in George W. Bush—but it also has a gentle ambling quality and a creative connection to such greats as writer Walker Percy and photographer Walker Evans, whose father was also named Walker.
