 The local Hindus started calling them "nosto seikh" meaning "spoiled Shaikh".But as more number of people got converted to Islam with time these people came in contact with mainstream Muslims, and the term "nosto seikh" slowly got islamicised into "Nashya seikh".The Nashyas trace their origin to the indigenous communities of Koch Rajbongshi of northern West Bengal, though some of them are also from Mech community.
