Irunkōvēl
Irunkōvēl also Irungkōvēl, Irukkuvēl, Ilangōvēlar was a title of the Irunkōvēl line of Tamil Velir kings. The Irunkovel line of kings ruled over Kō nādu identified with the Kodumbalur and surrounding areas in ancient Tamilakkam. They trace their lineage to the clan of Lord Krishna; one of the inscriptions at Kodumbalur belonging to one of the Kings in the Irunkovel line, namely Tennavan Irunkōvēl, declares that he belonged to the race of Krishna.
