Gavin, a name with Scottish roots, has stepped into the spotlight, replacing the dated Kevin, thanks in part to pop-rock sensation Gavin DeGraw and Bush lead singer Gavin Rossdale.

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.'

Lochlan and Lachlan are running neck and neck and both rising into the Top 1000. Which spelling you use is purely a matter of taste.

Hank is a midcentury guy nickname (which actually dates back to the seventeenth century) of the Al/Hal/Dick school, which has been on recess from the playground for decades.

Hanks Aaron and Greenberg (born Henry) and Hank Williams (born Hiram) Sr and Jr. are worthy namesakes.

Ben, the diminutive of Benjamin or Benedict, can easily stand on its own as a simple, strong, nice-guy choice, though it's somewhat attenuated. Ben is this generation's Bob or Bill.

Kellen is German in origin and Irish in spirit. Kellen has fallen a bit in popularity for boys since its peak in 2012, but it has possibilities for girls too. In fact, Kellen's similarity to such feminine names as Helen, Ellen, and Kelly makes it feel more unisex or even female, though Twilight actor Kellan Lutz has done much to popularize this name for boys.
