Jax

Jax is a modern English name that originated as a short form of Jackson, itself a medieval English surname meaning son of Jack, where Jack is a long-established pet form of John, derived from the Hebrew Yohanan meaning God is gracious. The name gained independent use as a given name in the late twentieth and early twenty-first centuries, boosted in part by pop-culture figures and the television drama Sons of Anarchy, whose lead character bore the name. It shares its ultimate Hebrew root with John, Jonathan, and Ian, as well as the full forms Jackson and Jaxon.
