Lily is the most popular of the popular delicate century-old flower names now making a return, thanks to its many irresistible attributes: a cool elegance and a lovely sound, a symbol of purity and innocence, and a role in Christian imagery.

Caroline is a perennial classic, one of the elite group of girls' names that's ALWAYS ranked among the Top 1000 and that's been in the Top 100 since 1994. Elegant yet strong, Caroline calls to mind the Kennedy Camelot years and Princess Caroline of Monaco.

Crisp and colorful, Autumn is the most popular season name in the US — the only one in the Top 100 in recent years — though Summer and Winter don't rank too far behind. Cool and gentle at the same time, it also ranks highly in England and Wales.

Frilly and feminine, Nicolette is the name of an enchanting princess in the medieval French romance, Aucassin et Nicolette, but really got its publicity from the heyday of Desperate Housewives and its star Nicollette Sheridan. It peaked in the US back in 1993, when it ranked at #327.

This spelling adds a little more femininity to the neutral Lee. Leigh and sister Lee were quite popular in the 1960s and 1970s among the first cool wave of unisex names for girls, but now have vanished from the Top 1000. The Biblical Leah is preferred.

Krista may be past its peak -- along with all similar C-starting sisters and their K variations -- yet it's still a pretty name.
