“ CHESNEY, CHARLES CORNWALLIS (1826–1876) , brevet-colonel royal engineers, was a nephew of General Francis Rawdon Chesney [q. v] , in whose house he was born, and to whom he owed his first advance in life. He was the son of another Charles Cornwallis Chesney, who had been a captain in the East India Company's Bengal artillery until ill-health obliged him to return to England, where he died in 1830. The younger Charles Cornwallis was born near Kilkeel, in county Down, on 29 Sept. ”
