[5] He probably was a member of the Irumporai/Porai line, a collateral branch of the Chera family (dominating the Kongu country with Karuvur/Karur as their headquarters).

Chelva Kadungo Vazhi Athan, father of Perum Cheral, was praised for his possession of Kodumanam (present-day Kodumanal) and Pandar (Koyilandy?)

[6] Perum Cheral is famous for the conquest of the fortified Thagadur, the stronghold of the Adiyaman chieftain Ezhini (who was aided by the Chola and Pandya).

[5] Perum Cheral also seems to have defeated a minor Idayar chief called Kazhuval or Kazhuvul [and emptied his city Kamur/Kazhur].

[1][7] The inscriptions record the construction of a rock shelter for Chenkayapan, a Jain monk on the occasion of the inauguration of Kadungon Ilam Kadungo, son of Perum Kadungon, the son of king Athan Chel Irumporai/Irumpurai as the heir apparent ("Ilamgo").
