Easton’s Bible Dictionary

Hadar : Adod, brave(?).

  1. A son of Ishmael (Genesis 25:15); in 1 Chronicles 1:30 written Hadad.
  2. One of the Edomitish kings (Genesis 36:39) about the time of Saul. Called also Hadad (1 Chronicles 1:50,51).

It is probable that in these cases Hadar may be an error simply of transcription for Hadad.
