Heroes and Prince Charmings

The cool form of James in the 1970s and '80s for both sexes. Still a more stylish short form than Jimmy, though many parents will want to call James by his entire, not-very-long name.

A biblical place name with trumpeting verve and strength.

King David's father turned 1980s cowboy, Jesse is now down in popularity. The name is associated with a wide variety of bearers, from outlaw Jesse James to Olympic athlete Jesse Owens to activist Jesse Jackson to current actors Jesse Tyler Ferguson and Jesse Eisenberg. The spelling Jesse is more usual as a boys' name while Jessie is more traditional for girls.

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.

Jonas has a slightly more grandfatherly image than the English version of his name, but that only adds to its retro appeal. And though it may lag behind Jonah in this country, Jonas is riding a huge wave of popularity in Europe, where it ranks highly in Germany, Switzerland, Austria and Norway.

Josiah—a biblical name with lots of quaint, old-fashioned charm—makes a much fresher sounding alternative to either Joseph or Joshua, combining the best of both. Josiah is among the several Biblical boys' names that have been on the rise this decade.

Killian – aka Cillian – is a spirited yet resonant Gaelic name that was borne by several Irish saints and could make a distinctive replacement for the dated Kelly.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.

Though the fuller Lancelot has for the most part been shunned as a 'too-much-name' name, the short form Lance has been consistently in or around the Top 500 since 1938, climbing as high as Number 76 in 1970. It was used as a character name by Walter Scott as far back as 1823. Lance is also the name of a medieval weapon, making this name all boy.

Lane is a recent hit name, that could be used for either gender, but is much more popular for boys. It's a surname that projects the pleasant picture of narrow, tree-lined country roads.
