The mill, dating back to 1865 as a corn mill, was subsequently leased by James Rowlie and Robert Davis, who transformed it into a
flax spinning mill known as the
Tandragee Flax Spinning Company. This enterprise was unsuccessful, leading to the business entering liquidation in 1871. Following this,
Thomas Sinton acquired the property, including its machinery, as part of the expansion of his company from its original location in nearby
Laurelvale. In the 1880s, it stood as the predominant employer in Tandragee, providing jobs for over 600 individuals, with nearly every household in the town depending on it for their income. A horn would sound across Tandragee, signalling the workers to begin work at 6:00AM. This sound was able to be heard in
Acton, located four miles away from the mill. == 21st century ==
