Dear Pooja Regards.Thanks for your message. It is true that this cast is quite uncommon in India. Now ofcourse one comes across few references through net etc. In Chandigarh also I used to wonder if there is any one with this surname. But I was happy that suddenly one day I rceived a phone call from a dargan family and thereupon we met. It was a strange excitement.All these families I came across were displaced from Pakistan, which to me seems to have come from a common ancestory.
