Bulky surname honoring Grandpa Henry or Saul Bellow's Rain King.

Can a name as virtuous as Hope be cool and trendy? Strangely enough -- yes. But though this optimistic Puritan favorite is experiencing substantial popularity, Hope is too pure and elegant to be corrupted, a lovely classic that deserves all the attention it's getting.

Though some might find it a bit heavy-booted, Ivan is one of the few Russian boys' names to become fully accepted into the American naming pool.

A cute diminutive of Jack, already technically a nickname for John, famously borne by Hong Kong actor, director and martial artist Jackie Chan.

Jackson is one of those names that's much more popular than you think, coming in near the top of our annual Playground Analysis, which ranks names by grouping all their spellings together. There were nearly 17,000 baby boys named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 3 boys' name.

Jazz as a full name is used slightly more often for boys than girls and has a distinctive, well, jazzy feel. Jazz is also occasionally used as a nickname for Jasper, much more often for Jasmine or Jazlyn. Could work as a middle name.

Jeter, which of course is used as a first name only because of Yankee star Derek, rhymes with Peter and may be derived from the French surname Jette, which was often bestowed on foundlings because it means "thrown out," or the German Jetter, an occupational name meaning "weeder." If your husband insists on Jeter, counter with Percival.

Jordan became one of the top unisex baby names in the heyday of basketball's Michael Jordan, and is still among the most popular unisex names starting with J. The name was originally given to those baptized in holy water brought back by Crusaders from the River Jordan, the only river in Palestine, and the one in which Christ was baptized by John the Baptist.

A name of multiple identities: a somewhat soap-operatic single-syllable surname, a homonym for the biblical bad boy Cain, and, when found in Japan and Hawaii, it transforms into the two syllable KA-neh. Kane also has multiple meanings: in Welsh, it's "beautiful"; in Japanese, "golden"; and in Hawaiian, "man of the Eastern sky."

A favorite Muslim name, Kareem first appeared on the US Top 1000 list in 1972 (jumping in at Number 405!), coinciding with the early career of basketball great turned writer Kareem Abdul-Jabbar (born Lewis Alcindor). It has continued to chart every year since.

The Russian version of Katherine is usually Ekaterina, but this Slovak form is used throughout Eastern Europe and may be more friendly to the American ear.
