In the genealogical line of Turvasu, the second son of Yayāti (Yayati), Marutta was without a son. So he adopts Duṣmanta (Dushmanta) of Puruvaṁśa (the hereditary line of Puru), as his son. According to Vāyupurāṇa (Vayupurana), this adopted son is Duṣkṛta (Dushkrita).
According to Brahmāṇḍapurāṇa (Brahmandapurana), Sarupya is the son of Duṣmanta. Āndīra (Andira) is the son of this Sarupya. Andīra had four sons, namely –Pāṇḍya (Pandya), Kerala, Cola (Chola), and Kulyā (Kulya).
According to Matsyapurāṇa (Matsyapurana), Duṣmanta’s son is Varūtha (Varutha). Ḍīra(Dira) is the son of Varūtha. The four sons of Ḍīra are: Pāṇḍya, Cola, Kerala, Karṇa.
In Vāyupurāṇa (Vayupurana), the name of Duṣkṛta (Dushkrita) is mentioned as the son of Marutta. There it is said that Duṣkṛta’s son is Śarūtha, and Sarūtha’s son is Janāpīḍa (Janapida) whose sons are : Pāṇḍya, Kerala, Cola, Kulya and so on.
Though there are variations among the Purāṇas (Purana, Mythological Scriptures), F.E Pargiter has argued that Āndīra is the grandson of Duṣmanta of Puruvaṁśa (Puruvamsa). He points out that Duṣmanta’s son is Śarūtha (Sarutha), and Āndīra is the son of this Śarūtha. Āndīra had four sons named Pāṇḍya(Pandya), Kerala, Cola (Chola), and Kulyā (Kulya). It is possible that the kingdoms occupied by them came to be named after them.
