Lost Girl

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.

Popularized in the 1940s by Lana (born Judy) Turner, today Lana is synonymous with American singer-songwriter Lana Del Rey. Although it has been rising steadily since the early 2000s, Lana still sits in the popularity "sweet spot" – familiar, but not overused. Simple, sleek and seamlessly international, it makes a great choice.

Lauren was derived from Laurence, an English name from the Roman family name Laurentius, meaning "from Laurentum." Laurentum, an ancient Italian city, got its name from the Latin word laurus, meaning "bay laurel."

Liam is the top boys' name in the US, holding the Number 1 spot for the past seven years and also ranking as one of the most popular boys' names around the western world.

Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.

Mary is the English form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Massimo is a Latin charmer, much more appealing than the old-fashioned Mario, and is a charismatic member of the Maximus/Magnus family.

More common -- when it was common -- with the Meyer spelling.

Not one but two Spice Girls are named Mel, which led to it briefly being more popular for girls than boys in the 90s and early 00s, but it has now fallen out of favor for both sexes.

Nadia, an accessible Slavic favorite, has a strong run of popularity in the US in the early 2000s, partially thanks to the character on Lost called Nadia but actually named Noor, but it's since slumped down the rankings. An earlier inspiration was Romanian gymnast Nadia Comaneci, who won the 1976 Olympics.

Very much in style, especially after its starring role in Six Feet Under, Nate is one of a new generation of nicknames that go directly on the birth certificate. Other similar names: Sam, Jack, Mack.

Nelson is a rather stiff and dated surname name that is sometimes used to honor distinguished South African activist Nelson Mandela, as Celine Dion did for one of her twin boys. Other notable associations are with the British Admiral Lord Horatio Nelson, New York Governor Nelson Rockefeller, novelist Nelson Algren and movie operetta star Nelson Eddy. It was also the given name of "Rabbit" Angstrom, protagonist of John Updike's series of novels.

Patrick, long tied to a hyper-Irish image, is enjoying something of a renaissance as a stylish classic, as it has long been considered in England. Along with such choices as Charles and George, Patrick has escaped overuse in recent decades.

Paulo suffers in comparison to the richer and more authentic-sounding Paolo.

Rainer is one of those baby names that is still under-the-radar but has been quietly gaining traction: The number of boys who've received the name has doubled in the past decade, to just under 50. Part nature name and part traditional German name for boys, Rainer can claim a place among the two-syllable r-ending baby names so fashionable for boys today.

Associated with Reynard the cunning fox in medieval European animal tales. Reynard can make an unusual yet historic choice for a modern boy, a modern day Richard or Robert.

Roman is an ancient name trending in a major way. A surprise hit name of recent years, Roman now ranks in the Top 100 not only in the US but throughout the English-speaking world, and is rising in other European countries as well.
