 The survey states that numerous mills were erected around the Great Famine (Ireland) period to meet increased demand for the processing of Indian meal and it was thought Clonmoyle Mill was built for this reason as between 1847 and 1854.The exact year of construction was uncertain, but a grinding stone, said to be a replacement from another mill, bore the date 1856.Clonmoyle Mill was said to have first been operated by 'Charles Colthurst of Ballyvourney' and that methods introduced by him were still followed in 1944, and the mill independently operated, some ninety years later.
