Will has definitely replaced Bill, not only as a nickname for William but as a stand-alone name as well, partly thanks to England's Prince William, also known as Wills. Currently outside the Top 1000 in the US and the UK, it wouldn't feel totally out of style. 
 Will maintains a nice old-fashioned, down-home charm, and with recent references such as Will Smith, Good Will Hunting, and Will and Grace, it has taken on an air of understated cool.
 Most celebrities known as Will were christened William—Shakespeare, legendary humorist Rogers, cartoonist Eisner, and actor Arnett—but others were not. Will Smith was born Willard and Will Ferrell was originally John William.
 A key character on Glee was Will Schuester.

If you're looking for a name that's light and breezy, this could be it. A name from mythology: Zephyrus/Zephyr was the Greek god of the west wind, and with its similarity in sound to the likes of Stefan or Seth, its zippy Z initial and cool Y, it is primed to rise up the US charts.
 
Frequently seen in computer and video games thanks to its mystical quality, it is also a character in the children's book Silverwing, and in the Babar books--as a monkey. It features in the TV series My Little Pony, the short animated film How to Train Your Dragon: Homecoming, and in the manga series, One Piece.
 Robby Benson and Karla De Vito named their son Zephyr in 1992, and Zephyr Benson is now an actor himself. More recently it was chosen by tech entrepreneur Sean Parker for his baby boy.
 
Thanks to these cultural references, and the more general interest in myhtological names, Zephyr has doubled in popularity over the last decade and was given to nearly 190 boys in the US in a recent year.
