ensign. He landed in Ceylon in 1783 with the
73rd Regiment. In 1795, he was appointed
Fort Adjutant of the

In 1799, Lieutenant Turnour was dismissed from command following an inquiry instituted by the Governor on irregularities in the Mannar Pearl Fishery which found "gross and incalculable fraud". Thereafter, Turnour Snr tried his hand in trading business between Indian and Ceylon which failed, prompting him to return to Jaffna insolvent in 1807. He was able to gain appointment as Revenue Agent of the Wanni, Assistant Collector of Jaffna in 1813 and served as Sitting Magistrate and Fiscal. He died in April 1813.
