As a Trini, I do not believe there are these 'races' that others may see as distinct.
As of mixed ancestry (mezclado) I may look Indo but I do have African and European ancestry also with an Anglo surname (more or less) and I only identify as Trini.
I love Diwali, Eid, Ramadan, my parang music (navidenas) love my roti, pelao (food).
If anything, I want to find out more about Carib and Arawak culture as the base culture, which is practically extinct except in recent years some sister tribe in Venezuala who visits T&T for ciltural exchage.
There are a few but most are mestizo or mixed with Carib/Arawak, Indian (from India), European and African!
Do you know what is the main tribe of Warao? I do not know whether they are Carib or Arawak or a separate tribe. I am sure that remnants of language spoken by the surviving indigenas can be traced to either one!
