Are Gotras basically clans? Why do some people claim Gotras off of the Rishis? like Bharadwaj? or Kashyapa? like i met a rajput who was of the sisodia clan, and said his gotra was kashyapa. and i met a janjua rajput who said his gotra was bharadwaja.
also where can i find the books called "bharat ka anjana" and "modern history of jats"?
