The Irish Tourist Association survey of 1944 confirms Clonmoyle House as the residence of Mrs Young, who also 'owned nearby Clonmoyle Flour Mills'. A separate survey entry is contained for Clonmoyle Flour Mills, giving the company name of 'John Young and Sons Limited, Clonmoyle, Coachford', which company appears to exist to this day. 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. Wheat was kiln dried in the loft, heated through a perforated floor, and then ground into flour by stone rollers driven from the mill wheel. The older milling method employed was said to be preferred. Oats and barley were also ground for the feeding of cattle, pigs and poultry. Visitors were admitted to the mill, free of charge, but at their own risk.
