Though closely associated with the great medieval Florentine poet Dante Alighieri -- who's so famous most people skip the last name -- it's not as much of a one-man name as you might think. Heck, it's not even a one-poet name, thanks to British pre-Rapahaelite Dante Gabriel Rosetti. Though especially well used in the Italian-American community, it would make a striking name for any little boy.

The appealingly energetic Dax, with its trendy X-ending, re-entered the Top 1000 in 2007. Its somewhat sci-fi vibe emanates from his appearance as a fictional being in the Star Trek universe, seen on the TV show "Star Trek: Deep Space Nine." The Power Rangers character Dax Lo was the Blue Ranger.

Devon, spelled like the lovely seaside county in Britain that inspired the name, has crashed since its heyday around the Top 100 in the 1990s. Despite its use as a female name, for example for Devon on the TV show The 4400, Devon continues to be far more popular for boys than for girls.

The name's rarity means it carries few preconceptions, allowing a child to define it through their own personality. Parents might choose Dacso for its distinctiveness and the blank slate it offers in terms of cultural and historical associations.
