Jax
Meaning
modern short form of Jack/Jackson, ultimately from John, traditionally 'God is gracious'
The story
Jax is Jack compressed to its most modern possible form, ultimately John underneath, God is gracious at the root, as our records trace it. The stories of Knox, Lennox and Maddox on this site all name Jax as the squad's fourth member; here is the member itself. The record is young and steep: about 250 in the 1990s, 2,200 in the 2000s, then 15,500 in the 2010s, seven times over, the exact seasons a motorcycle club's conflicted prince wore the name on television's most-watched cable drama; decade buckets point, they do not convict. It stands at 7,400 so far this decade. In our records it goes to boys about 25,100 to 220. Three letters, one X, eight centuries of John behind it: Jax is the oldest name in the room dressed as the newest.
