jezebel was a zidonian from tyre and sidion. Nebuchadnezzar was from Babylon or Persia which is modern day Iraq. Both were wicked and destroyed the people of God, King Nebuchadnezzar converted to Judism in the end. There is no back information to support they were related other than what is stated.
