Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity, in the US at least. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century and now ranks at its highest point ever, in the Top 50.

Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.

Rugged but gentle, Rhys is the traditional Welsh spelling of this name, which can also be anglicized as Reese or Reece. Up until 2010, Reese was the preferred spelling in the US, perhaps because parents were concerned about mispronunciation. However, Rhys has since taken over for boys and is now used twice as often as Reese.

Short, sharp, and cool, Jett is a contemporary choice that connotes both gemstones and jet engines. Rarely used before the 90s, John Travolta, and then George Lucas, helped to put the name on the map by choosing it for their sons.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.

Gus is a homey grandpa nickname name that can work as a short form for any of the above or stand on its own as a cutting-edge replacement for Max and Jake--though it was off the Top 1000 from 1978 until 2016, when it squeaked in at Number 999.

Though Jules hasn't been on the US popularity list in fifty years, it is a current hit in its native France—where it's currently in the Top 10—and we can definitely see it making a comeback here, being far more romantic than, say, Jim.

As flinty and steely as Mr. Eastwood.

A strong single-syllable surname with a joyful meaning, Tate is finding a place on more and more birth certificates.

Cole -- a short name that embodies a lot of richness and depth -- has long been associated with the great songwriter Cole Porter. It's quite popular in Scotland.

A Top 10 name from the 1880s until the 1920s, Frank has been falling for decades but last year reversed course for the first time in a century, edging up the popularity list a few notches. And Frank still has a certain warm, friendly real-guy grandpa flavor that could come back into style, like other such choices as Jake and Jack.

Chosen for their daughter by Bruce and Demi (inspired by the To Kill a Mockingbirdcharacter), and for her son by Tai Babilonia, an interesting choice for either sex, with overtones of a "good scout" and the upstanding qualities of a Boy/Girl Scout.

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.

Rhett has been more tied to Gone with the Wind than even Scarlett, but now we're hearing rumblings of its finding new and independent favor among parents, perhaps emboldened by the growing popularity of Scarlett.

A top ranking choice in England and Wales, making frequent appearances on the Telegraph Announcments, Rafe feels equal parts rugged, amiable, and posh. Traditionally seen used a variant of Ralph (itself from the Old Norse Ráðúlfr), it came into use in the 17th century to reflect this particular pronunciation.

One-time beach-boy compadre of Glenn, Greg, and Gary that originated as a nickname for a tall person, Grant has become a no-nonsense, career-oriented grown-up and one that is seeing new appreciation. It was chosen for his son by actor Morris Chestnut. It has cultural cred via artist Grant Wood, whose best known painting is 'American Gothic.'

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

While John Wayne and Duke Ellington are worthy role models, the reason Duke is currently enjoying a revival and returned to the Top 1000 in 2013 as one of the year's fastest-rising boys’ names is more likely due to the name given to high-profile TV couple Giuliana and Bill Rancic. Christened Edward Duke, he has always been called by his middle name, just as Edward Duke Ellington was. Duke is just one of several aristocratic titles being increasingly used by ordinary citizens.

Cal is a nickname style name that feels as friendly and calm as it does cool and breezy. While its longer forms have proved more popular over the years, Cal as a stand alone has dropped on and off of the US Top 1000 since the 1880s.
