A marriage between Chinnappa Nadar of Megavarnam group and Parvathi Ammal , sister of Sulochana Nadar - Naattanmaikarar group took place. As they had no children they ( Chinnappa Nadar and Parvathy ) adopted Kumarasamy who belonged Megavarnam group.

Kumarasamy married  Sivakami the daughter of Sulochana Nadar ( Parvathy Ammal brother's daughter) .  Kumarasamy - Sivakami Ammal gave birth a male child in 15th July of 1903. The child was first named as Kamatchi by its grand mother Parvathy Ammal. Since she worshipped Goddess Meenakshi she named the child as Kamatchi . Though  all called the child as Kamatchi with love and affection Sivakami Ammal used to call the child as Raja. Then all became to call the child as Raja. Kumarasami , who thought that the name of the god should also be  in the name of his son mingled both the names ( Kamatchi + Raja) and named him as KAMARAJA.  Four years after the birth of Kamaraja his sister Nagammal was born.
