One of the four perfectly proper spellings of this name ranging from the spare (but poetic) Eliot to the full-blown Elliott. Elliott and Elliot are the two most popular, and they have given to almost the same number of baby boys in recent years.

Milo is most commonly considered to be Germanic name derived from the Latin word miles, meaning "soldier." However, there is evidence to suggest it also may have independently spawned from the Slavic root milu, meaning "merciful." Milo predates brother name Miles, a variation that evolved when the name immigrated to the British Isles in the Middle Ages. Mylo is an alternate spelling.

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.

Cool and charming, with plenty of flair and sophistication, Julian manages to strike the balance between being a sensible classic and contemporary choice. Appealingly international, it is no wonder Julian is a rising star.

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel. Ezra is now at its highest point ever, but its intuitive streamlined spelling and deep roots could make it a worth successor to Elijah in the Top 10 -- or even to Liam or Noah at Number 1.

Evan has a mellow nice-guy image that has kept it popular, while it has been widely used in Wales since the nineteenth century. And interestingly—and surprisingly—enough, Evan charts highly for boys in France.

Jonah, the name of the Old Testament prophet who was swallowed by the whale, only to emerge unharmed three days later, is increasingly appreciated by parents looking for a biblical name less common than Jacob or Joshua, yet not too obscure. Plus, Jonah comes with a ready-made nursery-decorating motif.

Ari, the short form of Ariel (or any other Ari- beginning name, such as Aristotle) stands up better as a boys’ name than its progenitor does. It is also short for Aristotle, as in Onassis, and is a prominent character on TV's Entourage -- the uberagent Ari Gold.

This anglicized form of the Irish surname Ó Cathaláin links back to the Irish given name, Cathal. Similar to Callum, Caleb, and Calvin, it might feel more usable outside of Ireland and Scotland than its origin name.

Hot young actor Alden Ehrenreich, the new Han Solo, gives this formerly-stodgy surname name an attractive new image, making it a fresh successor to Aiden or Holden. Before it got this fresh shine, Alden was among the classic Thanksgiving baby names.

Barrett is one of many surname names that are up and coming for boys in recent years. Barrett joints Bennett, Beckett, and others in the trend of "-tt" ending boy names taking over the charts.

A cool, rugged sounding name, Calder is connected to an ancient Scottish clan, an English village, and a Scottish River, along with the sculptor Alexander Calder, who invented the mobile (as in, kinetic sculptures powered by motors or air). Meaning "rocky water" or "stony river" in the ancient Brittonic language, it makes a creative yet outdoorsy choice.

Titus, once seen as a slightly forbidding Roman, New Testament, and Shakespearean name, was brought back to contemporary life in the USA by the TV series Titus 2000, increasing in popularity along with other revived ancient names like Linus and Silas.

Zion has taken off in recent years, particularly after singer Lauryn Hill used it for her son back in 1997 and incorporated the name into a hit song. It combines a user-friendly Ryan-Brian sound with the gravitas of religious significance and has that cool, on-trend Z initial. The Hebrew pronunciation is 'tzeeyon', though among English speakers, it will likely be said as ZY-on.
