What are the most common Indian surnames (last names)?
I've read the Wikipedia entry for Indian names (http://en.wikipedia.org/wiki/Indian_name) so there's no need to cite it or explain to me how surnames are formed, used or not used.
What I'm wondering about is what that article doesn't explain: The prevalence (or lack) of surnames (last names) in India, which are most common, and [if possible] the meanings of the most common surnames, if appropriate.
Thanks in advance! I always pick a best answer, so this is a sure 10 points for the person with the best answer.
