Has fallen off its Kathie Lee Gifford inspired peak in the 1990s, but since that notably celebrity baby is now a grownup and out of the limelight, Cassidy may once again reclaim its own Irish charm.

Just the kind of casual, flippant nickname that upscale Brits are putting on their sons' birth certificates, but few U.S. parents are.

This sleek, warm-hued spelling spin on Rowan was chosen by Sharon Stone for one of her three sons back in the 2000s and it has since risen in popularity in the US. While it remains a long way behind its sometimes sound-alike Rowan, it was still given to more than 140 babies in a recent year.

Phoenix is a New Age name symbolizing rebirth and immortality. It's also a place name, a color name, a mythological name, AND an animal name, combining several of today's hottest trends in one appealing package.

Hunter has been dropping a bit for the past few years but is still one of the leaders of a distinctive band of boys' names that combines macho imagery (Hunter, Austin, Harley) with a softened masculinity. Hunter was for years attached to gonzo journalist Hunter S. Thompson; Josh Holloway used it for his son.

Andrea — a feminine form of Andrew (and a male name in several European cultures) — comes with a good selection of pronunciations — ANN-dree-a, AHN-dree-a, or ahn-DRAY-a — each with a slightly different image: girl next door/slightly affected/downright mysterious

Kiera entered the American popularity list in 1988, though it lags behind the alternate spelling Keira, largely due to the fame of actress Keira Knightley.

No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.

With Matthew sounding somewhat exhausted, and ancient endings sounding new again, this New Testament apostolic name makes an appealing and recommended choice. Both Mathias and Matias are well used in the Hispanic community, and throughout Europe. Will Ferrell and his Swedish wife chose Matias for their second son.

Straightforward single-syllable name, though children named Lyle may get tired of hearing "Lyle, Lyle, Crocodile". Lyle was at the height of fashion in the 1920s, which makes him due for a comeback right about now. The double L certainly gives it a fashionable sound.

Aveline is a name that's long been an obscure cousin of more widely-used choices, but may come into its own riding the tail of the megapopular Ava, which may derive from the same root.

Despite a return to such feminizations of male names as Josephine, Clementine, and Theodora, starchy Henrietta has not made it into that group. Still, if you look hard enough, you'll see that Henrietta has the same vintage charm.

Though it may not be as sweet and gentle as, say, Violet, the purple-hued Hyacinth still might hold some appeal for the parent seeking a truly unusual flower name.

Earthy but sophisticated, Marshall is an occupational surname, and despite the sounds, it isn't military or martial in any way. Rather, it stems from the Norman French for someone caring for horses.

The girls' name Kyra sounds like the also popular Keira/Kiera, but has a different root. There are twice as many baby girls named Keira as Kyra, with Kiera in third place. Kyra now ranks at #590 and is most familiar via actress Kyra Sedgwick.

Caesar, the name of the greatest Roman of them all, is rarely used outside Latino families, where the Cesar spelling is preferred —as in activist Chavez and Dog Whisperer Millan. Its original meaning is debated — either "long-haired", "blue-gray" (as in eyes), or "cut" (because Julius Caesar was supposedly born by cesarian section) — it came to be the title to denote all Roman emperors and it is from the name Caesar that many other European royal titles are derived, including Kaiser and Tsar.

The unisex Blake, which indeed has two conflicting meanings, has a briskly efficient image when used for a girl.

Wilhelmina might once have been condemned as a clunky relic best left in the past, but a steadily increasing number of parents are dusting it off for their 21st century babies. A reasonably popular choice in the 19th century, but out of favor by the 1950s, in the last decade, Wilhelmina has attracted more attention, and was given to around 110 babies in a recent year.

Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.
