Dean may sound to some like a retro surfer boy name, but it is once again climbing up the popularity chart in the USA. For decades it was associated with Dean (born Dino) Martin; more recent representatives include Dean Cain, Dean McDermott and Dean Koontz -- not to mention Jared Padalecki's dreamy Dean Forester in Gilmore Girls.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.

Nova has the feel of both newness, from its meaning, and great energy as an astronomical term for a star that increases suddenly in brightness before fading.

Fletcher is a common surname with a touch of quirkiness; it definitely fits into the So Far Out It's In category--and moving further in all the time along with other occupational names from Parker to Forester.

Celia, splendidly sleek and feminine, is a name that was scattered throughout Shakespeare and other Elizabethan literature, but still manages to feel totally modern. Derived from the Latin Caelius, it means "heavenly".

A Top 10 name from the 1880s until the 1920s, Frank has been falling for decades but last year reversed course for the first time in a century, edging up the popularity list a few notches. And Frank still has a certain warm, friendly real-guy grandpa flavor that could come back into style, like other such choices as Jake and Jack.

The musical, sylvan Sylvia seems poised to join former friends Frances and Beatrice and Dorothy back in the nursery.

Jonah, the name of the Old Testament prophet who was swallowed by the whale, only to emerge unharmed three days later, is increasingly appreciated by parents looking for a biblical name less common than Jacob or Joshua, yet not too obscure. Plus, Jonah comes with a ready-made nursery-decorating motif.

Cosy and warm but with plenty of substance and strength, Tess is a literary diminutive that works perfectly well as a stand-alone name. Stylish in the Netherlands, it currently sits outside the Top 1000 in the US, where Tessa and Teresa are currently preferred.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

Phineas is the English variation of Phinehas, a Hebrew name likely derived from the Egyptian name Pa-nehasi. Pa-nehasi, meaning "the Nubian" can also be translated as "the bronze-colored one." The Egyptians distinguished themselves from their Nubian neighbors through differences in skin tone.

Charlie is a friendly, boyish nickname name now used slightly more frequently for girls than boys, with over 2200 baby girls named Charlie last year versus about 2100 boys. That makes Charlie one of the most evenly-balanced and most popular unisex names around today.

Though ancient, Marcus now sounds more current than Mark, in tune with today's trend towards us-ending Latinate names.

Simone, the elegant French feminization of Simon, strikes that all-important balance between unusual and familiar, and it's oozing with Gallic sophistication. A dated choice in its native France, gymnast Simone Biles brings new bounce and spark to name.

A favorite in England and Wales where nicknames as given names are very much the norm, Tilly has the potential to catch on in the US, given its similarity to the popular Lily and Ellie and the rising stars Millie, Billie, Kallie, and Nellie.

King David's father turned 1980s cowboy, Jesse is now down in popularity but still a Biblical classic, ranking in the US Top 1000 for its entire history. The name is associated with a wide variety of bearers, from outlaw Jesse James to Olympic athlete Jesse Owens to activist Jesse Jackson to current actors Jesse Tyler Ferguson and Jesse Eisenberg. The spelling Jesse is more usual as a boys' name while Jessie is more traditional for girls.

This attractively energetic Italian version of the classic Matthew is primed to move further and further into mainstream American nomenclature. Mateo is technically the Spanish version, but many parents in the US use the two spellings interchangeably.

Bea is a former old lady name that's cute again as a short form — and is now beginning to stand on its own. Bee is a variation that, like Bea, can work as a diminutive for any name that starts with the letter B, or in the middle. Bea actually stood alone on the popularity lists for four years at the beginning of the twentieth century — and it could happen again.

Jonas has a slightly more grandfatherly image than the English version of his name, but that only adds to its retro appeal. And though it may lag behind Jonah in this country, Jonas is riding a huge wave of popularity in Europe, where it ranks highly in Germany, Switzerland, Austria and Norway.

Booker would make for a very cool name, for writers, reformers, R & B fans and those wanting to pay tribute to Booker T. Washington.
