The Ponnambalam-Coomaraswamy family was an immensely powerful family in Sri Lanka which many say was responsible for the 20th century rise of the Tamil Vellala caste of the island. Many members of the family have received knighthoods from the British Sovereign in the past. To this day, the family continues to be respected across the island and its members continue to hold positions of power.
The ascendance of the Ponnambalam-Coomaraswamy family commences with a Coomaraswamy (1783–1836) from Point Pedro joining the seminary that Governor North started for producing interpreters. Coomaraswamy passed out and served as an interpreter from 1805. He was rewarded by the Governor with a Mudaliyar position at the age of 26 and became the Jaffna Tamil with the highest government appointment. He played a critical role as the Tamil-English interpreter when the Kandyan king Sri Wickrama Rajasinghe was captured in 1815. He was rewarded with a gold chain and medal by Governor Brownrigg in 1819 for loyal service to the British crown. (Vythilingam 36-43) There were allegations that he was not from the Vellala caste. (Jayawardena 209). James Rutnam's research has shown that Coomaraswamy's Father was Arumugampillai, a South Indian, who had migrated to Gurudavil in Jaffna. (Tribune 1957)
Arunachalam Ponnambalam’s (1814–87) step Father Ariyaputhira was Coomaraswamy’s brother-in-law and in 1844 Ponnambalam married Coomaraswamy’s daughter Selachchi. Ponnambalam was appointed cashier of the Colombo Kachcheri in 1845 and deputy Coroner for Colombo in 1847. Many leading Englishmen were his friends and it transpired in the 1849 Parliamentary Commission that he used to lend money to government officials. (Vythilingam 58)
His three sons P. Coomaraswamy (1849–1905), P. Ramanathan (1851–1930) and P. Arunachalam (1853–1926) were national figures and two of them, P. C. and P. A. married two daughters of Namasiyayam, an extremely successful Broker. This closely related and endogamous clan emerged as the pre-eminent Tamil family of the country and rose to national elite status. (Jayawardena 210-212)
Despite their anglicized background which propelled their rise, the family presented a staunch Hindu appearance and assumed the role of ‘Patrons of the Vellalas in Colombo. However many of its members; Muttu Coomaraswamy, P. Coomaraswamy, P. Ramanathan married western women. Ananda Coomaraswamy was married four times to western women.
They helped many young Tamils to secure employment in English Banks and Mercantile establishments. On the death of Mudaliyar Coomaraswamy’s wife in 1897, the leading daily, ‘The Ceylon Independent’ wrote “to her and her husband, almost every important Hindu family in the city owes its rise”.
