Boys

The name August is at its highest point since the 1890s, when it ranked among the Top 100 boy names in the US. And deservedly so, given its great meaning, historic roots, and cool nicknames.

Ethan is a name that succeeds in being at once classic and fashionable, serious and cheery, strong and sensitive. Given a big boost via the name of the Tom Cruise character in the Mission Impossible film series, Ethan has fallen from its peak at Number 2 in 2009 and 2010, but is still popular in the US along with several other countries.

With Old European vibes, Johan is a variant of the classic John, similar to the Latin, Hebrew, and Germanic forms, Iohannes, Yohanan, and Johannes. Conjuring up the image of the classical composer Brahms or the astronomer Kepler, while still feeling timeless and distinctive, Johan has been in the US Top 600 for most of the 21st century, helped along by Heidi Klum and Seal using it for their son in 2006.

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.

Highly popular in Germany, Norway, Lithuania, and Austria, Lukas is a spelling variation of the also extremely popular Lucas. The "K" spelling gives it extra kick and a more international, globe-trotter feel.

There's Rhys and there's Reese (now more popular for girls) and there's Reece, and we particularly like the traditional Welsh spelling, which entered the list in 2004, possibly influenced by Jonathan Rhys Meyers, of The Tudors, and Welsh-born actor Rhys Ifans.
