Emmett, honest and sincere, laid-back and creative, is on the rise as a male cognate of the megapopular Emma and Emily, not to mention being a character in the popular Twilight series.
 Emmett originated in England as a masculine diminutive of the German Emma; the Hebrew characters pronounced eh-MEHT mean truth, so that might be considered another definition. Emmet is another, less popular spelling.
The death of young Emmett Till helped spark the civil rights movement.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Derived from the Latin meaning "lion", Leo is one of those names, like Luke and Finn, that many people assume must be short for something but that is authentically a complete name in its own right. That said, Leo can but short for any number of names, from Leonardo in Latinate languages to Leon and Leopold in Germanic languages. We've even heard of little girl Leonoras and Leonies called Leo: How cute is that?

Leo's simplicity makes it an international star, ranking in the Top 100 in countries as diverse as Ireland and Israel, Spain and Sweden, Austria and Australia. Leo is a truly diverse name, a perfect choice for any family crossing countries or blending cultures.
 
Leo's only real downside is its universal popularity and familiarity. If you call your child Leo, you and they will almost certainly encounter many other Leos over the years of all types and ages. Plus or minus? Or both?
 
Penelope Cruz and Javier Bardem called their son Leo, as did actress Kim Raver, NASCAR driver Jeff Gordon and Kristin Olson. 
 Famous Leos of the past include Pope Leo the Great, a number of early saints, and Leo Tolstoy, as well as Dead End Kid Gorcey, colorful baseball manager Durocher, influential gallerist Castelli and the leonine MGM icon. There have been Leos seen on everything from The West Wing to Charmed to Grey's Anatomy to Seinfeld's Uncle Leo.

Favored by first-generation Jewish families from the affluent Guggenheims to criminal-producing Lanskys; now Meyer is pretty much relegated to poolside gin games in Boca.
