The story that has been doing the rounds for centuries now is that the first Costa settler in India had sailed to the subcontinent in the company of Vasco da Gama. But there is also information that the Costas are Brahmins, and so Indians by origin. We have no documentary evidence in support of either statement; we only know that, at the close of the sixteenth century, the Costa family lived in the fortress of Rachol and several of its members held posts that were the preserve of blue-blooded Brahmins only. How can one reconcile these two theories?
