Indian (as in East, for you North Americans) surnames.
I have a character in a short story who is of Indian descent (3rd generation immigrant, vaguely observant Hindu) whose first name is Devesh. I am seeking a surname for him, or to find out if his name is from an area where surnames are not used, in which case I would go with the first initial convention. Problem is, I don't know whether or not Devesh has a general locale associated with it, so I can't give him a proper surname. Help? Anyone?
