Suetonius Grant Heatly (sometimes spelled as Heatley; 1751–1793) was a judge employed by the British East India Company and, with John Sumner, established what is considered to be the first coal mine in India. Heatly was born in Newport, Rhode Island, in what is now the United States, to a family that had a Scottish heritage.and was loyal to the British Crown. That loyalty caused them to move to England around the time of the American Revolution. His connections and ability were useful in his career with the East India Company, which he joined in 1766 and for which he held various offices.
