C > K

Caia Caecilia was the Roman Goddess of fire and women. The name Caia would make a truly fresh alternative to the flagging Maya, with which it rhymes.

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.

An Irish and Welsh form of Catherine, Caitlin was a boom name of the eighties, rocketing from obscurity (Americans first heard it via the wife of doomed poet Dylan Thomas) to the height of popularity in the space of a decade. The original name was gradually eclipsed by its myriad spelling variations -- Katelyn and Kaitlyn both soon topping it on the popularity lists.

Cameron was once a rising star for boys only, but Cameron Diaz almost single-handedly transported it into the unisex camp back in the 80s.Though there are still eight times as many boy babies named Cameron as girls, it is currently in the US Top 600, where it is joined by Camryn and Kamyn.

This name of a touristed island in sight of Los Angeles makes an attractive and newly stylish variation on the classic Catherine or overused Caitlin.

Time was, even C-starting Catherines who called themselves Kate spelled it with a K, but Cate Blanchett changed all. Cate is now as acceptable as (but not as well used as) Kate. Cait might be short for Caitlin.

If your ancestry is Italian, you may want to consider this elegant twist on a classic.

Catherine is one of the oldest and most consistently well-used girls’ names, with endless variations and nicknames. The Catherine form feels more gently old-fashioned and feminine than the more popular K versions. Most stylish nickname for Catherine right now: Kate...or Cate, a la Blanchett.

Chloe is a pretty springtime name symbolizing new growth. Though slightly off its peak in the Top 10 in 2010, Chloe still ranks in the Top 20 and is solidly a modern classic.

Christina, a pretty and feminine, crystal clear classic, may be trending downward, but it's never out of style. Christina's short forms Chris, Christie, and Tina all seem dated—making the royal Christina best used in its full glory.

Claudia is a classic name with ancient Roman roots. Never truly in or truly out, Claudia feels like a strong, modern choice that hits the sweet spot between too popular and too unusual..

Among the Top 20 names of the 1990s, today's Courtney is more apt to be the babysitter than the baby. Courtney has dropped since its peak at Number 17 in 1995. Familiar from Courtney Love and Courtney Cox.
