Though Eoin is a Gaelic form of John, its Anglicized pronunciation links it directly to Owen. Eoin is currently a Top 30 name in Ireland. Other variations: Ewan, Ewen, Evan and Eoghan (pronounced as Owen but also translated as Eugene).

An Old World name that might have a chance to rise again with other ancient and worldly forms. Be sure to say yo-HAHN-es.

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.

Yannick originated as a diminutive of Yann, the Breton form of John. However, it has since become popular as a standalone name in its native region of Brittany, as well as in France as a whole, where it peaked at #31 in 1973-4. It remains well within the Top 500 in France to this day, and has also seen regular use in Belgium, Switzerland, the Netherlands and Quebec.

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

Will this old-fashioned nickname make a comeback, now that Jane has shed her "plain" image? Janie is cute and approachable, and would stand as well on the birth certificate as Josie and Jessie do now.

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.

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.

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.

One of the most enduring French names, this form of John has been borne by philosophers (Rousseau and Sartre), artists (Millet, Arp) and fashion designers (Gaultier) alike. Often used in a double name with the likes of Pierre, Paul, and Luc, it is a classic in its native country,

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

This quintessentially common last name makes a distinctive if first, given to more than 230 babies in the US in the most recent year counted. It has doubled in use over the last decade.

Evanna is the name of a Harry Potter actress who pronounces it ee-vah-na. This might be considered another international feminine form of the many variations of John; Ivana, Giovanna, and even Joan are cousins of Evanna. It could also be a compound name, combining Eva and Anna.

This newly invented name is most likely a combination of Jane and Vanessa. Though it may not have as long of a history as more traditional names, Janessa has been a staple on the bottom half of the US Top 1000 since the mid-1980s. Perhaps surprisingly, it peaked at Number 524 in 2004.

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.

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.

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.

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.

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.

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.
