Mercedes is one of the few names attached to luxury living that we can wholeheartedly recommend, it being a legitimate Spanish appellation stemming from one of the epithets given to the Virgin Mary--Santa Maria de las Mercedes, or Our Lady of the Mercies. The car, by the way was named after the eleven-year-old daughter of the Daimler company's French distributor in 1901.

Janet started as a pet form of Jane but has long been used independently. Jane is a feminine form of John, which derived from the Hebrew name Yochanan. Janet can also be considered a variation of Jeannette, a derivative of Joan and another feminization of the name John.

The ultimate midcentury nickname, retaining a good measure of retro charm, was chosen for her son by Mira Sorvino.

Sean may be off its peak for boys, but there were still 1300 baby boys named Sean in the US in the most recent year counted, versus only five baby girls. In fact, there were fewer than 30 baby girls given the spellings Sean, Shaun, and Shawn combined. So while this name has been long used for girls, it remains in only occasional use as a feminine name and is not truly unisex in the way that names such as Rory and River are.

Juan, the Spanish version of John, is ubiquitous in the Spanish-speaking world, and is familiar internationally via such references as Don Juan and San Juan.

Milla originated as a diminutive of names like Camilla and Ludmilla, but has since become well established as a name in its own right in several European countries. Milla Jovovich is a Ukrainian-born actress and supermodel, while Milla is also used for a character in the novel and musical adaptation, Wicked.

A Top 100 name from the 1930s all the way through the 1950s, it's now firmly in Mom -- or Grandma -- land and supplanted for babies by Joanna.....or even great-grandmother Josephine. In its heyday, it had a host of variations, including JoAnn and Jo-Anne.

Pronounced just like Jean in the English-speaking world, but as the more unusual zhahn in France, this has sailed away with the first wave of French favorites: Denise, Michelle, et soeurs.

With Old European vibes, Johan is a variant of the classic John, similar to the Latin, Hebrew, and Germanic forms, Iohannes, Yohanan, and Johannes. Conjuring up the image of the classical composer Brahms or the astronomer Kepler, while still feeling timeless and distinctive, Johan has been in the US Top 600 for most of the 21st century, helped along by Heidi Klum and Seal using it for their son in 2006.

Ianto is a lively and unique spin on John, possible familiar to American sci-fi fans via the popular character on Torchwood.

Animated Gaelic name popularized by singer Sheena Easton, also brings to mind Sheena, Queen of the Jungle, the Amazonian comic book and TV series heroine. Sine is considered to be and English equivalent of Jane or Jean.

Shawn is a phonetic spelling of Sean that may be past its peak – it was a Top 30 name in the early 1970s – but is still quite popular for boys: over 500 baby boys were named Shawn in the US in the most recent year counted vs 800 given the original Sean spelling.

Popular form of John in Germany. Just remember to pronounce it YAHN-nik, which most English-speakers won't. Jannick is another spelling.

Gian sounds (almost) like John, so there's some potential for confusion, but the spelling makes it unmistakeably Italian. It could be a solution if longer names like Gianni and Gianluca aren't your style.

It's difficult to imagine anyone using the first name Jonesy -- and in fact, in the most recent US tally, there were nearly 100 babies named Jones but none named Jonesy. Still, this is a name that many people with Jones for a name, last or first, end up being known by, and as a nickname, it's sorta cute in a Skip, Chip, Bitsy kind of way.

A spunky diminutive of Hanne, itself derived from Johanna or Johanne.

Simple and pretty and user-friendly, the Welsh Sian was used by U2's Dave "the Edge" Evans for his daughter. In Welsh, it is also spelled Siân.

Evan is a boys' favorite that has been given the feminine touch by talented actress Evan Rachel Wood. If you want to move beyond Eva and Evelyn and like unisex names, this may be a good bet for you (though like Evan Rachel Wood, you may want a feminine name in the middle name position to clarify matters). Evanna is also another alternative.

One of the best known of the Irish girls' names, thanks to singer Sinead O'Connor. Though it's still in the Irish Top 100, it's no longer quite as fashionable in Ireland as Aoife or Aisling. But by now everyone in the Western World knows it's pronounced shin-aid and so would have no trouble fitting in on an American playground.

A standard form of John in Dutch, Swedish, Norwegian, Danish, Czech, Polish, Slovene, German, and Catalan. Properly pronounced yahn (in most of these languages), most Americans will still equate it with the Brady Bunchesque girls' name Jan, which is now officially extinct.
