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.

A relatively modern name, it didn't come into use in its native Wales until the late nineteenth century, and even then, it wasn't a mainstream choice until the middle of the twentieth century. Pronounced as CA-riss, the beginning sound is like the one cat or Catherine, not said to rhyme with Claire.

Trevor, a British standard, took a long time to cross the Atlantic, but finally began its rise here in the 1980s. It is now a thoroughly naturalized citizen, though it still retains a touch of Anglo class.

Because of Gwyneth Paltrow, this has almost become a one-person name, but not in the prohibitive there's-only-one-Oprah sense.

The aristocratic--if not haughty--Roderick was nevertheless consistently in the Top 1000, reaching as high as Number 221 in 1967, when it was not uncommon to run into a Rod or a Roddy. It's at a low point right now, but we can envision it being revived as a neglected, dignified grandpa name, perhaps when Rod is no longer a potentially embarrassing nickname..
