Sincha and Duncha Khan - these names appear muslim to me, so why on earth would these muslims try to escape marauding tribes of their own kind?????????????? According to Nepaltara555, Sincha and Duncha Khan ran away from Rajasthan and entered India. Now where is this Rajasthan today- inside India. In those times of Muslim invasion (9-10th centuryAD) too Rajasthan was a part of India. So what nonsense is this guy writing. MY SLEUTH WORK: who were Sincha and Duncha Khan? They were Nepaltara555's great-great(100 times) grandfathers. They were Genghis Khan's issues. Recently DNA testing was done on Nepaltara..'s public hair and it was proved that he has Genghis khan's genes in his blood.
