Since we wrote a book called Beyond Jennifer & Jason, Madison & Montana, encouraging parents to move beyond overused names, it's no secret what we think of this trendy surname name, inspired by a mermaid named Madison in the 1980s movie Splash.

There are several Percivals scattered through the Harry Potter series, which might help transform the old-fangled, fussy image it has accrued. Actually, the original Percival was the one perfectly pure Knight of the Round Table, a worthy hero. The name was invented in the twelfth century by a poet named Chretien de Troyes, for his ideal knight in the poem Percevale, a Knight of King Arthur.

A name of multiple identities: a somewhat soap-operatic single-syllable surname, a homonym for the biblical bad boy Cain, and, when found in Japan and Hawaii, it transforms into the two syllable KA-neh. Kane also has multiple meanings: in Welsh, it's "beautiful"; in Japanese, "golden"; and in Hawaiian, "man of the Eastern sky."

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name. In fact, it's already a fairly popular choice on Nameberry and a solid presence on the England and Wales charts, where it's featured in the latter half since the 90s.

The Spanish Camila, pronounced ka-MEE-la, is the fastest rising version of this ancient Roman name, but recent royal Camilla may have helped promote the British brand. In Roman myth, Camilla was a swift-footed huntress so fast she could run over a field without bending a blade of grass.

This jaunty Celtic surname -- the most common family name in both Ireland and the US -- is totally viable as a first. The arguably most famous Murphy is TV's Murphy Brown, and indeed the name is twice as common for baby girls as for baby boys today. But still, it's solidly gender neutral and works equally well for all sexes.

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name.

Always the top spelling of the name; Neil peaked in the 1950s, but then enjoyed a second coming following the fame of such Neils as astronaut Armstrong and singers Sedaka, Diamond, and Young. Now semiretired.

Duncan is jaunty, confident, and open, a Scottish royal name that's brimming with friendly charm and makes it into our golden circle of names that are neither too popular nor too strange. Popularity aside, Duncan is one of the most classic Scottish names for boys.

Luella is a sleeker spelling variant of the girls' name Louella and is now more popular than the original. Sweet, but lively, it was a popular name in the the early 19th century, but fell out of favor in the 50s. Now, after a 60 year absence, it's back in the charts, in the US and the UK.

In the World War II era, Roger had nothing but the most positive associations, actually used by military personnel to mean 'Received and understood'--or A-OK, and though it is now on extended furlough, it does have a long and distinguished history. Introduced to England after the Norman Conquest of 1066, Roger soon became very popular there, with nicknames Hodge and Dodge, and had a long run later in the U.S, remaining in the Top 100 for 55 years.

Lula has a firecracker personality, a singing and dancing extrovert. Interesting that Lulu was a Top 100 name when the Social Security list was born in 1880, but it's been sliding ever since and has not been in the Top 1000 for decades. Modern parents in love with Lulu might well reverse that trend.

Biblical name Cain was, until recently, seldom heard outside of the Old Testament and soap operas. Although Cain's murderous actions will always make this name difficult for some, Cain, Eve and Adam's firstborn, was a farmer - making this a good choice for those with farming connections. Long outshone by Abel, Cain is starting to find a broader audience, helped along by homophones Kane or Caine.

The energetic Russian nickname name Sasha is being used increasingly on its own, though since the prominence of the First Daughter, more than 90% of the American babies named Sasha are girls. Sacha Baron Cohen bears one of the alternate spellings.

Ned is a gently old-fashioned Nancy Drew-Bobbsey Twins-era short form for Edward that sounds cooler than Ed and is enjoying a small style renaissance.

Edgar is an Old English name historically associated with the tenth century English king known as Edgar the Peaceful. There was also a King Edgar of Scotland.

When Gary cracked the Top 10 in 1950, it was one of the first nonclassic boys’ names to do so, largely due to Gary (born Frank) Cooper, who was renamed after Gary, Indiana, his agent's hometown. Now, a 65 years later, Gary isn't particularly high in the charts, and has lost any glitter it had. May we suggest the fuller name Gareth?

Marcel, despite distinguished namesakes including Proust and Duchamp, suffers from a terminal headwaiter image in this country. But along with its sister name Marcella and French variation (and Jolie-Pitt pick) Marcheline, Marcel may be on the brink of a style renaissance.

Gareth, the name of a modest and brave knight in King Arthur's court, makes a sensitive, gently appealing choice, used more in its native Wales than anywhere else.

This Anglicized form of Bearach or short form of Finbarr was in the Top 200 in the USA for 50 years until the early 80s when it rapidly fell out of favor. Barry has not yet found popularity in the modern era - but that may well change as people rediscover their love of classic figures like musician Barry White, baseballer Barry Bonds or even Barack Obama, whose nickname as a young man was Barry.
