Udaiyar
Nathaman are the descendants of Meiporul Nainar.Moopanar & Suruthiman are the descendants of the two wives of Kulasekaran.Malayaman are the descendants of Narasinga Munaiyar Nainar.
Kulasekaran, Meiporul Nainar and Narasingha Munaiyar are the sons of Thaervann Malaiyamaan (who ruled the regions around Thirukovilur), from his wives Senbagamaalai (daughter of a Chola king), Kanchanamaalai (daughter of a Pandya king) and Padmavati (daughter of a Chera king) respectively.
Thaervan Malaiyamaan is also sometimes referred in literature as Thaerveegan/Deiveegan, and is some times mentioned that he had a brother named Thirukkannan. Thaervann first married[3] one of the daughters (Angavai) of King Paari (Paari-Velir or Vel-Paari), but did not have any children with her (a minority contest this claim by saying that her lineages were absorbed along with that of the other wives).
Thaervann was the son of the more-famous Malaiyamaan Kaari who had also ruled the regions around Thirukovilur c.90- 122 C.E. Mukkulathor claim that Malaiyamaan Kaari belong to the Malayaman descendants of the Kallar clan, one of the three clans of the Mukkulathor confederacy.
Another claim is that Malaiyamaan Kaari, along with the other Kadai Ezhu Vallalkal (The Seven Great philanthropists), belonged to the Velirs, who originated from the Yadu Kshatriya clan that had migrated southward from Dwarka.
