Names that contain an x — at the end, in the middle, and even at the beginning — have been climbing in fashionability since Angelina Jolie named her oldest son Maddox around the same time Max morphed from old man to cool kid name.

Some of these are obscure names that include the letter x; others, like Jaxon, come by their x by design. Our favorite x name choices include both the classic and the new.
