Son of Brock or son of Braxton
Braxson is a modern American invented name, likely created as a patronymic variation of the names Brock or Braxton. It follows the popular trend of adding the '-son' suffix to established surnames or given names to create a contemporary feel. Because it is a relatively recent creation, it lacks a deep historical or etymological lineage beyond its English roots.
