David is an enduring worldwide classic, used from ancient times to the present day.

Rudy is one of those names that has been consistently in the US Top 1000 since the early 20th century without ever becoming overwhelmingly popular. It peaked back in the 1930s, when it briefly entered the Top 250, though more recent years have seen it make the latter end of the charts. Certainly more stylish than its parent name, Rudolph, which has been relegated to reindeers in English speaking countries, Rudy was given to 300 boys in a recent year.

Noelle is the feminine variation of Noël, a masculine given name derived from the French word for "Christmas." As a word, Noël originated as a variant of nael, which evolved from the Latin natalis, meaning "birth." Noelle and Noel have traditionally been given to children born around Christmastime, particularly in the Middle ages.

The name Christian has fallen a bit from its 90's and 00's heights, but it's still quite popular. Once considered overly pious, Christian is now seen as making a bold statement of faith by some, while also having secular appeal for others. Christian's enduring popularity may be influenced by such celebrities as Christian Slater and Christian Bale, not to mention the fashion world's Dior, Lacroix, Louboutin and Audigier.

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.

Not cutting edge, but still graceful and feminine.
