Hemingway readers will recognize this as the name of Papa's first wife (and, eventually, actress Mariel's grandmother). But in Victorian times, Hadley and Hedley were actually more popular for boys.

Flynn, a charming Irish surname, is still used only quietly, despite its easygoing, casual cowboy charm, unlike Finn which is a star of this genre. Flynn was the choice of Orlando Bloom and Miranda Kerr for their baby boy, and is also the middle name -- used as his first -- of a son of Miranda's fellow supermodel Elle Macpherson, of Gary Oldman's son Gulliver and Marley Shelton's daughter West.

Eddy, recently used by Celine Dion for one of her twin boys, was chosen to honor Eddy Marnay, who produced her first five records. Though less common a nickname for Edward than Eddie, Eddy is used more often on its own.

Originally a nickname for a third-generation son, as in Thurman Thackeray III, Trey is now being given to others, and it has also expanded to Treynor and Treyton.

Monte, pronounced with two syllables as brother Monty, is an old-fashioned nickname-name that's reclaiming a certain amount of dash and charm. It was recently chosen by actor Guy Pearce--which may signal a comeback.

Britney Spears' little sister Jamie Lynn was one of the first to put this nickname on the birth certificate. Cute for a child, but we recommend giving her the option of the full name for later use.

Benji is undeniably cute, much in the way of a — yes, an adorable movie mutt. Ben is the handsome traditional short form of Benjamin, but Benji makes a more unexpected nickname

Harley is a tough guy, while the rhyming Marley has a softer, gentler image. The name brings to mind reggae great Bob Marley, as well as the lovable dog from bestseller Marley and Me.

One of the first generation of cool surname names, now largely used for girls in the US, but still popular for boys in its native Scotland. A prominent association for Brits is former prime minister Tony Blair, who was leader at the time of the Iraq War.

Jethro, though the biblical father-in-law of Moses, has suffered for a long time from a Beverly Hillbilly image, but some really adventurous parents might consider updating and urbanizing it and transitioning it into the hip o-ending category.

Malachi is one of the surprise Biblical hits of recent years, in the US Top 200, and now spelling variation Malaki is in the Top 1000 too. Both names are pronounced with a long final i, as in "eye," but the Irish variation Malachy is MAL-ah-kee, which Malaki might mimic instead.

Perhaps the ultimate nicknamey name, Ziggy manages to sound cool, cutesy, spiky, and energetic all at once. It brings to mind the glam-rock of Bowie's Ziggy Stardust and the cool vibes of reggae musician Ziggy Marley, along with the contemporary-but-vintage appeal of Teddy, Mack, and Albie.

Just as Seamus/Seumus is Irish for James, Hamish is the Scottish form — one that's not often used here, but still redolent of Olde Scotland. If you're ready to go further than Duncan and Malcolm, out to Laird and Ewan territory, this may be worth consideration. It also sounds just like the Yiddish word for homey.

Mika is a sparky and stylish Japanese girls' name that translates easily to English. Also used as a Slovene and Hebrew diminutive for Mihaela and Michaela, as an alternative spelling to the Biblical Micah, and as a Greek diminutive of Dimitra (via Mimika), it is a truly multi-cultural choice.

This short form of Mikael, a variation of Michael, may originate in Finland but it's most popular in Germany and The Netherlands. Mika can make a cute and original way to honor a Michael in the family, but be prepared for a lot of people pronouncing it with a long i as in Mike.

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.

Mackey is a masculine name that originated as a surname derived from the Gaelic Mac Aodha, meaning "son of Aodh" or "son of Hugh." Aodh was a popular Irish and Scottish name meaning "fire." As a first name, Mackey emerged through the tradition of using family surnames as given names, a practice particularly common in American naming customs. Though not among the most popular first names, Mackey has a friendly, approachable quality with its upbeat sound and casual feel. It carries associations with Irish and Scottish heritage while maintaining a distinctly American character. The name exudes a cheerful, unpretentious personality and offers the friendly nickname Mac.
