Obviously there are Portuguese influence in Goan region and some hindus including brahmins perhaps got mixed with the Portuguese , but you have to understand they would have had to relegate their religion and caste after getting mixed with the Portuguese .Sir,
Don't get upset. If it makes you happy, you can disparage on my self, or community or family.

Your assumption will have some substance only if we consider the wholly corny idea that those fair and light eyed Konkan Brahmins are actually bastards of the Portuguese. Impossible.
