Just like Deeks, Nyron Asgarali was de person I was going to name. His mother, Gauri Sankar, was a Brahmin Hindu, and his father, Emmanuel Asgarali, was a Muslim.
He made 103 in the second innings of a match against Guyana in de Oval in February, 1952. His son, Gregory Asgarali, also represented T&T.
Now there's a Chiki Sampath (from Tunapuna) who scored 123 against Barbados in Kensington Oval in January 1949. I eh sure if he is Indian, but given that Roland Sampath is Indian, Chiki might be de one. Maybe somebody could confirm his ethnicity.
