Girls

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

Hazel has a pleasantly hazy, brownish-green-eyed, old-fashioned image that more and more parents are choosing to share. Former Old Lady name Hazel reentered the popularity lists in 1998 and now is near the top of the charts.

The disgraced heroine of The Scarlet Letter's name, after long neglect, just might have a chance at revival, following in the wake of sister-name Esther. We've characterized her elsewhere as an eccentric aristocrat, much more accepted in the U.K. than she has been here.

Hollis is a surname-name used quietly for both genders. At last count, it was given to over 200 baby boys and 160 baby girls in the US. Now a Top 1000 name for boys, it could well break into the charts for girls too in the coming years.

Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example. Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

Joel is one of those boys’ names that's never been super-popular yet has never been UNpopular either -- it's been in the Top 400 in the US since we started keeping statistics in 1880. So it's inevitable that its female form Joelle would gain visibility too, and indeed Joelle was used most widely during Joel's reign in the Top 100, from the late 1960s through the early 1990s.

Juniper is a fresh-feeling nature name -- it's a small evergreen shrub -- with lots of energy. A new favorite of fashionable parents, Juniper joins such other tree and shrub names as Hazel, Acacia, and Willow.

Contrary to popular belief, the name Kahlo has German origins, rather than Spanish. It derives from kahl, a German word meaning "bald." Mexican Artist Frida Kahlo was born to a German father, photographer Guillermo Kahlo.

Kali is a number of different things: a playful, contemporary twist on the name Callie; the Hindu goddess of destruction; an alternative spelling for Kaylee; a short form of the Arablic Kalila, the Greek Kalista, or the African American Kaliyah; a masculine name in India; and a trendy form of Kali(fornia).

This much less popular variation draws more from Karin.

Hungarian form of Katherine.

Hot R & B singer Kelis Rogers's name is a combination of those of her parents' -- Kenneth and Eveliss.
