A Goan Catholic in the world of business, he was a pioneer in the opium trade in China, long before the British thought of entering this branch of commerce.
Abbé Cottineau's Journal describes Sir Rogerio Faria's house as "commanding a most lovely view of the sea, the ramparts, the suburbs, the city, the Colaba island, and the West coast as far as the so-called Malabar Point.
De Souza[4] says that Faria made his fortune in "opium-peddling", and writes: "We are not able to fully collaborate the statement, but we are told by the otherwise critical Indo-Portuguese administrator-historian, J.H.
da Cunha-Rivara, that Sir Jamsetjee Jeejeebhoy, the most glamorous Parsee figures of the mid-nineteenth century in the annals of Bombay, started his prosperous career as a simple clerk in the firm of Rogerio de Faria.
The Goan journalist-editor A.M. da Cunha wrote a 30-page booklet [6] which Souza says "gives more details about the numerous progeny of Sir Roger than about him."
