Tobias is one of a number of s-ending boys' names that are riding a wave of popularity. With its Old Testament-Dickensian feel, it's a name with a distinguished pedigree.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s.

Nael - or Naël as it is often spelled - originated as a French diminutive of names ending in -nael, though in recent years, it has risen up the charts as a standalone choice. A Top 20 name in France, it is also popular in Belgium and Switzerland, where it fits in beside Léo, Sacha, Lou, Noé, and Ben.

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice.

A rare example of an a-ending boy's name that sounds masculine, Ilya has a large measure of creative Slavic charm. >p>Ilya Ilyich Oblomov is the central character in Goncharov's novel "Oblomov." Unfortunately, he spends most of his life in his bathrobe and slippers.

Isabelle is the French variation of Isabel, which emerged in the Middle ages as an Occitan form of Elizabeth. Medieval queens Isabella of Angoulême and Isabella of France helped popularize the name in the United Kingdom. Isobel is the Scottish version, Isabella the Italian, and Izabel is used in Brazil.

The Top 10 boys' name Elijah is derived from the Hebrew name Eliyahu, composed of the elements ’el and yah, both of which refer to God. In the Old Testament, Elijah was the prophet who went to heaven in a chariot of fire, a story sure to inspire any young Elijah.

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.

Elliot (which boasts several spellings depending upon how many 'l's or 't's you want to use) is a winner -- it has the ideal quality of being neither too common nor weirdly unique. Elliot had a style boost back in the early 1980s via the young hero of the movie E.T. , who was named Elliott. Since then there have been Elliots on Law & Order: SVU and Mad Men.

Energetic, sunny, and slightly romantic, Rafael is a popular choice in Germany, Spain, Portugal, and Croatia. Used internationally, Rafael is a Spanish variation of Raphael, that lends itself easily to the nicknames Rafi, Rafa and Rafe.

Lillian has ranked among the US Top 100 for the past 20 years, making it Lily's less popular but more grown-up cousin.

The origins of Samantha are not entirely clear, although it is commonly thought to be a feminization of Samuel with the suffix derived from the Greek anthos, meaning "flower." Samantha has been in English-speaking use since the eighteenth century, particularly in the American South, and drew attention via Grace Kelly's Tracy Samantha Lord character in High Society, featuring the song "I love you, Samantha."

Though some might find it a bit heavy-booted, Ivan is one of the few Russian boys' names to become fully accepted into the American naming pool.

Zara has multiple origins, but most notably is a variation of Zahrah, a name derived from the Arabic zahrah, meaning "blooming flower." Zara can also be a diminutive of the Bulgarian name Zaharina, a feminine form of the Hebrew Zechariah. Today, Zara is heavily associated with the Spanish fast-fashion empire of the same name.

Western novelist Zane (born Pearl!) Grey made this name famous. Now, it's in tune with the style of our times, retaining that appealing cowboy image.

Joan was the perfect name choice for one of the leading characters on Mad Men, being a quintessential girls' name of the period. A Top 10 name in the 30s, a Top 50 name from the 40s through the early 60s, it was the fifth most popular name in the country for three years running and ranks as one of the most common names for girls in the 20th century. But alas, Joan hasn't even appeared in the Top 1000 for a dozen years, and these days it's primarily associated with Joans of the generation of Joan Crawford, Joan Collins and Joan Rivers--just a few of the noted Joans whose ranks also include the singers Joan Sutherland, Joan Baez, Joan Armatrading and Joan Jett. But it's possible that modern parents who are reviving Jane might move on to Joan, inspired by Joan Hollaway Harris.

Although it has come to sound Irish, Dennis is one of the most widely-used French names (St. Denis is the patron saint of France) and harks back even further to Dionysius, the Greek god of wine and debauchery. It was introduced to England by the Normans.

In the Old Testament, Joel was one of King David's 'mighty men' and the name was taken up by the Puritans of the sixteenth century. In the mid 1960s, Joel entered the Top 100, and stayed there for about twenty years, as parents tried to jazz up and formalize old standby Joe by reviving this biblical name.
