Krishnamachari, Suganthi (30 April 2020). "Inscriptions talk of fascinating Kongu connection". The Hindu. Retrieved 17 April 2021.:"Krishna Menon of the Valluva Nadu royal family had five sons, of whom the fourth was Sankunni Valiya Mannadiyar, born in 1832. Sankunni Mannadiyar held a judicial post in Cochin. His son was Gopala Menon, born in 1884. Gopala Menon's wife, Satyabhama, belonged to a family in Mathur, which was referred to as Vadavanur Vellalar in copper plates. To Gopala Menon and Satyabhama, a son was born in 1917, who was to become famous not only in Tamil films, but in the political scene in Tamil Nadu. That son was M.G. Ramachandran! So M.G.R. had Kongu Vellala ancestors, both on his father's side and mother's side!"
