Jesus of Galilee and Jesus the Galilean are two English versions of the same name. “Jesus” (Yeshua‘) was a common name in His day. Jews distinguished people with common names by adding a reference to their father (son of Joseph), occupation (Jesus the carpenter), or the place they came from (Jesus of Nazareth or Galilee).
