Ash has Southern charm plus the arboreal-nature appeal. Plus your little boy will prize Ash as the name of the hero of the Pokemon cartoons. Ash can also be a dashing short form of Asher, Ashton, or any other "Ash" name.

Audrey is one of the girls' names that have been rising due to their connection to Old Hollywood glamour—in this case the eternally chic and radiant Audrey Hepburn. Audrey has another very different appeal as one of the elite group of girl names that mean strong, brave, or powerful.

One of the most romantic of appellations, Caspian is a geographical name referring to the large salty sea between Asia and Europe. It's also the name of the hero of C.S. Lewis's beloved Chronicles of Narnia, Prince Caspian.

Knight (as opposed to Night) is a name clad in shiny armor. This high-ranking word name was introduced by singers Kelis and Nas. Knight might join brothers King, Royal, and Noble in a new definition of royal baby names.

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.

The additional syllable makes Lark a masculine surname name.

One of the fierce new animal names new to name lists, helped by its strong x-ending.

African-American and women's rights activist Sojourner Truth was born as Isabelle into enslavement. She adopted her new name when she began traveling and preaching abolition in 1843. Sojourner is a heroine name that may, with the rise of spiritual word names such as Journey and Genesis, finally be ready for prime time.
