Their traditions assert that their ancestor Mahta Chandu Rai came from Mathra to Delhi and entered the Mughal service under Babur, who employed him with Raja Mal Janjua to drain the eastern Dhanni tract in the Salt Range, Gharka Kassar and Sidhar Manas afterwards aided them to colonise the tract and Babur granted Chandu Rai a percentage in the revenue of the Dhanni and other tracts of the Salt Range. Humayun granted Kali or Kalki Das, son of Chandu Rai a Sanad (dated 1554) of 30000 takas for the improvement of the tract and the family also received Sanads from Akbar to Aurengzeb. In the latters reign one branch of the tribe was converted to Islam, but most of its members are still Hindus and Sikhs.
