Well we still do not know what they started with for Turobunsingh. The Indians I have asked so far do not recognize Turobun. The above was just a guess. In looking at the garbling of British and Danish virgin Islands surnames in Puerto Rican civil records I got the impression that some of the results might have been influenced by the absence of teeth. An example of an attached honorary prefix can be found in Seepersad which I think is taken from Sri Prasad
