Holden is a classic case of a name that jumped out of a book and onto birth certificates--though it took quite a while. Parents who loved J. D. Salinger's The Catcher in the Rye are flocking to the name of its hero, Holden Caulfield -- not coincidentally in tune with the Hudson-Hayden-Colton field of names.

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.

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. Now it's just beginning to be given on its own again, appreciated for its earthy, sportsguy cool. Hanks Aaron and Greenberg (born Henry) and Hank Williams (born Hiram) Sr and Jr. are worthy namesakes.

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.

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.

A few decades back, this name -- which hardly shows its Irish roots -- evoked a man in a gray flannel suit; now, though still upscale, it's more likely to be attached to a female.

The fierce image of the Barbarian made a complete turnaround thanks to amiable talk show host O'Brien, making Conan one of the newly desirable Irish choices, a perfect alternative to Conor/Connor.

Truman is an upstanding presidential name that radiates an aura of integrity and moral truth, values any parent would want for a child. It seems definitely headed for a revival.
