Modern invention, possibly derived from Jalen or Galen
Jaelen is a contemporary American name, likely a creative spelling of Jalen. Jalen was popularized in the 1990s by basketball star Jalen Rose, whose name was a portmanteau of his parents' names, James and Leonard. Alternatively, it may be influenced by the Greek name Galen, meaning calm.
