Ultimate Wizarding World Baby Names

Jonquil is an unusual flower name that is less outlandish than Daffodil and less common than Daisy. It just might appeal to parents seeking a singular botanical option.

Unlike most flower names, Jonquil wasn't introduced until the 1940s, and saw some usage in the U.K. during the forties and fifties.

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.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

Justin has been widely popular since the 1980s, when parents were seeking a fresher 'J' boys’ name to replace Jason, Jeremy and Jonathan. It's been dipping in popularity a bit in recent years but it reached as high as Number 9 in 1990. At this point it's Justin that is suffering from overexposure.

Kassandra is actually the original form of Cassandra (Greek names do not have Cs), though most will see it as a Kardashianization, which is a shame! As you might expect, the C currently charts higher. Still, Kassandra can lead to all sorts of cute nicknames, such as Kassie, Kass, and Sandy.

Friendly mega-popular short form of Katherine that has definitively replaced Kathy, Katie is often given on its own. Going forward, though, Katie is more stylishly clipped itself to the grownup Kate.

Kingsley is a sophisticated Harry Potter name that entered the US Top 1000 in 2013.

This endearing nickname name is one Katherine pet form that predates all the Kathys and Katies, having been fairly common in the eighteenth century. With the current mini-craze for animal-related names, Kitty is sounding cute and cuddly again—she's already jumped back onto the U.K. list, at number 199.

Knight (as opposed to Night) is a name clad in shiny armor. This high-ranking word name was introduced by singers Kelis and Nas. Knight might join brothers King, Royal, and Noble in a new definition of royal baby names.

The K is silent in this royal but common Scandinavian name that is, in this country, linked to a single figure -- Notre Dame football coach Knute Rockne. Could easily be confused with Newt.

Evocative modern unisex choice brought into the spotlight by actress Lake Bell.

Lavender lags far behind sweet-smelling purple-hued sister names Violet and Lila, but is starting to get some enthusiastic attention from cutting-edge namers along with other adventurous nature names like Clementine and Marigold.

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.

Lemon is one of the more unique names related to fruit, compared with sisters Clementine and Apple. That may be because lemon is also a word that's slang for a clunker, something that doesn't work very well. No baby wants to feel like a Lemon, so this is one of those unusual names that is best avoided.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Leta has hipster cred as the daughter of cool mommy blogger Dooce. Related to the Greek mythological Leda, a great beauty who mothered another great beauty, Helen of Troy, Leta is a name that's as unique as it is historic: Only 14 baby girls were named Leta in the US last year, and 18 were named Leda. Pronunciation is lee-tah.

Appropriate for a girl born between late September and late October, Libra suggests both balance and freedom.

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.

If it's royalty you're after, stick with Earl or Prince -- this is too deified.
