Guinevere was the name of the beautiful but ill-fated queen of Camelot, for so many years eclipsed by its modern Cornish form Jennifer. Today, Guinevere could be a cool possibility for adventurous parents intrigued by this richly evocative and romantic choice.

One spelling variation that's more popular than the original, this somewhat old-fashioned name might be in honor of poet Gwendolyn Brooks, the first African-American to win a Pulitzer prize for poetry, or may be a way to get to the modern short form Gwen.

While Gwen may have originated as a short form of Gwendolen and Gwendolyn, these days it frequently stands on its own. Rocker Gwen Stefani has given it a shot of cool, and parents are choosing it as a standalone more and more often—Gwen hopped back onto the US Top 1000 in 2013 after an absence of over 30 years. Gwen could also be short for Guinevere.

This cross-cultural name, found in Wales, Brittany, and Spain, is a surprise star in the U.S in recent years, largely thanks to actor Gael Garcia Bernal. Also written as Gaël, it's a popular choice across Spain, Mexico, Chile, Uruguay, and France, and the US.

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.

Hard as it might be to believe, Gladys was the Harper of 1900, emerging almost out of nowhere to take the naming world by storm. It became a favorite among parents — and writers of romantic Edwardian novels, seen as alluring and unusual. One impetus was the 1870 Ouida novel Puck, whose heroine was the idealized beauty, Gladys Gerant.

A classic Welsh name, softer than Griffin and friendlier to spell than Gruffudd - that hasn't had as much love as it deserves elsewhere. Namesakes range from medieval kings to the philanthropist Griffith J. Griffith, who left land to the city of Los Angeles. It's great in full, but Griff is cool too.

Because of Gwyneth Paltrow, this has almost become a one-person name, but not in the prohibitive there's-only-one-Oprah sense. Also seen as Gwenyth and Gweneth, this mellifluous appellation is definitely becoming more and more appreciated by American parents-- enough to land it on this year's Top 1000.

Short, simple, gentle, undeniably Welsh but easy to spell and pronounce – there's a lot to like about this underused gem. In the States it's been almost exclusively female, perhaps due to the greater familiarity of Gwen, but it definitely feels like a candidate to reclaim for the boys.

With a noble air and a distinctive yet familiar sound, Gawain is drawn from Arthurian legend, in which he is one of King Arthur's loyal knights and his nephew. Also appearing as the hero of the 14th century poem, Sir Gawain and The Green Knight, his name is possibly borrowed from the Welsh Gwalchmai, meaning "May hawk".

Gwendolen, an ancient Welsh favorite, retired decades ago in favor of the short form Gwen, but now, as in the case all across the naming board, the nickname has faded and the more distinguished original is up for reappraisal.

An offbeat way to get to Gwen.

Now that the midcentury sound-alike name Gail for girls is sailing out to sea, Gael is becoming an increasingly popular name for boys -- and could make the gender switch in the opposite direction again.

The Gwendoline form may introduce pronunciation confusion -- does that last syllable rhyme with wine or win or when? We vote Gwendolen as not only the most proper but the clearest spelling, followed by Gwendolyn, with Gwendoline a distant third.

With Grace mega popular and Gracie on the rise, this modern compound name provides a trendy alternative. With the vibes of Brooklyn and Evelyn and the contemporary feel of Oaklynn and and Emberlynn, Gracelynn is currently in the US Top 400.

A strong, classic, simple name that has nonetheless never been overexposed.

The connection to a knight of the Round Table in Arthurian legend gives this name a hint of nobility. Geraint Thomas was a Welsh cyclist who competed in the 2008 Olympics.

The feminine version of the common Welsh name Glyn became somewhat known in this country via the charming Welsh actress Glynis Johns. Variations include Glenys and Glynys. With other Welsh names--Gwyneth, Bronwyn, Bryn, Griffith--now on the American table, Glynis could make a distinctive tribute to an Uncle Glenn.

Glenys, like Glynis, is a Welsh name that has never caught on outside Wales.

The most modern choice in this group, and the most distinctive; the Gwyn form is a common male name in Wales.
