I've only met one person named...

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.

Clarissa, the daintier version of Claire, has a long literary history of its own, having been featured in the novels of Samuel Richardson, Charles Dickens, and Virginia Woolf—Clarissa was the title character of Mrs. Dalloway—not to mention the 1990s teen sitcom, Clarissa Explains it All.

Sometimes used as a short-form of Catholic Pope name Anacletus, Cletus is an ancient name that has not-yet found the popularity of Theodore, Leo, Atticus and Max. It perhaps suffers from its association to the yokel character in The Simpsons , but we think it's time for a reconsideration, given how well it fits into several current trends. Nickname Clete is cute as a button!

This Native American tribe name is an attractive option for a boy or a girl. Tia Mowry used it for her son in 2011.

Cullen is an appealing Irish surname name that upped its cool factor considerably when it became the Twilight family name of Edward et al. It's considerably less popular than it was at its peak in 2010, but is still widely used.

Curran is a common surname in Ireland, but unusual even there as a first. With its savory feel, calling to mind curry and currants, Curran can make for an attractive update on Colin or Connor.

Perhaps too spicy for some, but this is a popular Gaelic surname that might appeal for those looking to honor a family branch or to fans of legendary British comedian Tim Curry.

Cyrus is one of those surprising names that have always ranked among the Top 1000 boy names in the US. On an upward trend since the mid-90s, Cyrus now sits in that comfortable place between too popular and too unusual.

The Hebrew form of Daphne, typically only heard among Jewish families in the US.

A small number of girls are given this Irish surname as a first name each year.

The most common form of Damir is of Slavic origins, deriving from the elements da, meaning "give" or "take," and mir, "peace." It's also seen as a variation of the Turkish name Demir.

In Greek mythology, Daphne was the nymph daughter of Peneus, a river god. Peneus saved Daphne from Apollo’s romantic obsessions by transforming her into a laurel tree. It is from this myth that the plant genus daphne, which contains the laurel species, gets its name.

Classical and Shakespearean name that may appeal if you like your names long, flowing and multicultural.

A star in the "tail" of the Cygnus constellation.

A twist on Darwin with the same friendly meaning. Its lovable-nerd feel is given a cool edge by several football players with the name.

The jazzy, ultra-cool Dexter, like most names with an "x," has a lot of energy and dynamism.

Diamond sparkled all through the nineties--reaching as high as Number 150 in 1999. Although its shine has diminished quite a bit, it remains in use.
