The ten families of Goud Saraswat Brahmins were amongst the aborigine settlers of the Chorao Island. The island was said to be a place of learning and also boasts a Sanskrit University. According to the Hindu deities and Temples by Rui Pereira Gomes, the island had ancient temples of Ganesh, Devki, Ravalnath, Kanteshwar, Mallinath, Bhaukadevi, Bhagwati, Narayan, Santa-purush, Chandeshwar and Dadd-sancol. Also Vanadevata and Roulu on Caroi Vado. When the Portuguese began to force Christianity in the Goan islands, many Hindus fled from chudamani and shifted Hindu idols via Mayem to Naroa and Marcela. The main deity Devaki-Krishna and its associated deities of Bhumika Devi, Mallinath, Laxmi Ravalnath, Katyayani, Chodaneshwar and Dhada Shankar were taken to Mayemwadem in Bicholim and then moved to its present location at Marcel. The Jesuits Christianised the island as they also followed this the Island of Divar and salsette (Saxti).
Chorao Island constituted of three communidades, namely the Chorao - GSB Vangors, Ambelim - GSB and Daivajna vangors and Caroi- 3 Daivajna vangors. A seminary called the Real Colegio De Educacao De Chorao was established in April 1761. A temple of Shri Devaki Krishna Bhumika Mallinath was rebuilt on 11 January 1934.
