1900+ Four Letter Boy Names

Nico is one of the great nickname names, full of charm, energy and effortless cool -- a neo Nick.

Enzo originated as the Italian variation of Heinz, a German name derived from Heinrich, related to Henry. It has historically been used as a short form for Italian names such as Vincenzo and Lorenzo. The most famous bearer of the name is Enzo Ferrari, founder of the luxury sports car brand.

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.

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.

Knox is an old Scottish surname that Brad Pitt (whose great-great-grandfather was named Hal Knox Hillhouse) and Angelina Jolie took out of the back cupboard, dusted off, and elevated to coolness--to the point where it entered the popular baby names list in 2009. Knox now ranks among the most influential celebrity baby names.

A classic in its native Scandinavia, Axel has a cool rock 'n' roll flavor in the US, thanks to Guns N' Roses' Axl Rose (born William). Axel is a popular Scandinavian form of the Biblical Absalom, who was a son of King David, and is the name of the title character of William Faulkner's Absalom, Absalom.

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.

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.

Leon is one of the leonine names that is extremely hot in Europe right now. Although it peaked here in the 1920s, it is slowly making its way back, and it could climb further with parents wanting a more serious and studious alternative to Leo.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.

Wren may not be as time-honored a bird name choice as Robin or even Lark, but it's more fashionable and fresh, with a gentle and earthy vibe.

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.

Amos is a robust biblical name that's being discovered by a new generation of parents in a major way.

Patrician to the core, Hugh was firmly in the Top 100 until 1903. It's never achieved those heights again, though it has always managed to remain in the Top 1000, scraping bottom at literally Number 1000 in 2006 before reversing course and heading back upwards.

Nael originated as a short form of names ending in -nael, such as Nathanael and Gwenael — a Breton name that was a minor hit in 1970s France. It has come to be more popular as an independent name, and currently ranks within France’s Top 50.

Unlike Pearl and Ruby, this is one gem name suited for boys, the final x making it sound strong and virile. Musician Iggy Azalea chose the name Onyx for her son.

Jace may sound like only half a name -- it's usually pronounced like the first half of Jason though some may consider it a spelling-out of the initials J. C. -- but it's a popular choice for baby boys. Jace has been heard on such TV shows as Teen Mom 2 and Duck Dynasty.

The Reid spelling is the most popular by half, probably because it feels more like a name than Reed, which looks more like a word. It's used occasionally for girls but this name is firmly in the boys' camp.

The long-neglected name of Adam and Eve's third son after Cain and Abel, Seth is appreciated for its gentle, understated presence -- and strong middle-name potential. It reached a high of Number 63 in the year 2000.
