His other sons, by his daughter Danand, included Brian, Iuchar, and Iucharba, who killed Lugh's father Cian. As an erec (a recompense fine), they were sent on a quest recounted as Oidheadh Chlainne Tuireann (The Tragedy of the Sons of Tuireann), one of the Three sorrowful tales of Erin. After Lugh had taken his elaborate revenge, Tuireann died of grief over their graves.
He is stated in various portions of Lebor Gabála Érenn to be the same person as Delbáeth mac Ogma, who is also credited as the father of Brian, Iuchar, and Iucharba. He is likely related to the Gaulish deity Taranis and thence to Thor of the Germanic people.
