Chaliyan

The honorific plural "Karanavar" is used for the community point man in the Bhagavathi temples. In old days, Koil Thampuran(a Namboothiri ruler) would nominate him.

Nair

The senior most maternal uncle was the head of the matrilineal joint families, known as Tharavadu, and was called Karnavar. The authority of the Karnavar in a family is unquestionable. Even after the decline of Matrilineal system, the word is used to denote authority, and elderly person.

Besides this, Karnavar is also a surname for some aristocratic Nair families in and around Budhanur, Chengannur, Kerala, India, all branches of the same original family at Budhanur. One legend is that it was conferred by Marthanda Varma the King of Travancore. While consolidating his newly found Kingdom of Thiruvithamkur (Travancore), the nephew(later Dharma Raja) and sister of Marthanda Varma were passing through the said area under the protection of Vattaparambil Valiathan and were attacked by the people of the Ettuveetil Pillamar. Marthanda Varma's brother in law and other fighters lost their life but the sister, the Rani of Attingal, and her son escaped and ran through the fields ("Budhanoor padam")where they met an elderly Nair man who was farming in the field. He addressed the old man as "Karnavar" and asked for his help. The old Nair helped him by hiding him and informed the nearbly feudal Lords known as Aaruveetil Madampimar who in turn informed the Vakkavanjipuzha Madhom, the head of which, known as the Vanjipuzha Thampuran, was an ally of Marthanda Varma. Eventually Marthanda Varma endowed him with riches and the hereditary surname of "Karnavar" when he became the Maharajah.
