Fresher, brisker and, yes, cooler than Summer or Autumn or Spring, Winter is now a full-fledged female choice, especially since Nicole Richie and Joel Madden used it for daughter Harlow's middle name, and Gretchen Mol picked it as her daughter's first, as did media mogul Sean Parker. Winter continues to be the preferred spelling and has risen in popularity significantly over the past few years.

This undiscovered unisex name has lots of flair. It was first noticed as a girl's name, starting in the 1980's, on the long-running daytime drama Search for Tomorrow, with the character Adair McCleary, who had ahead-of-their-time brothers named brothers Hogan, Cagney and Quinn. But since Adair has yet to find many takers, it would make a fresh and appealing choice.
