The appealingly energetic Dax, with its trendy X-ending, has been on the popularity list for the past seven years. 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.
In real life, actor Dax Shepard plays the TV character of Crosby Braverman on "Parenthood." His parents named him for the protagonist of the best-selling Harold Robbins novel, The Adventurers-- Dax Xenos.
Dax is also a French community famous as a spa.
Dax is unlikely to become popular in Australia, sounding too much like the word dacks, which means boys underwear.
