Meaning and history
Short form of Jackson, Jax appeared in the video game Mortal Kombat II in 1993 and first registered as a given name in the United States in 1995, when it was used only five times. It then grew steadily in popularity for about two decades, likely influenced by similar names such as Max and Dax and by a character of the same name on the American television series Sons of Anarchy (2008–2014).
