Mentioned in "The Serpent's Venom"
Del'nor was a male Jaffa and the father of Rak'nor. Prior to 1997, he had been spared by Teal'c when Apophis had ordered his death. Del'nor in turn had followed Bra'tac's rebellion and sought to give his son freedom from false gods by searing the Jaffa mark from Rak'nor's forehead. However, his family was killed by Apophis.
