The mill serviced the local area, including neighbouring Cregg Castle, and served as a feeding centre for the poor of Corrandulla during the Great Famine.

[1] The mill is on the Cregg River, which rises from a spring a half mile to the north and flows into Lough Corrib.

In the finalised 1853 edition of Griffith's Valuation, only the latter mill is mentioned as functioning at Cregg (in the townland of Drumgriffin), with Patrick Wade listed as the miller.

[7] In 1918 a newspaper article noted that "efforts are being made to re-establish the Cregg Corn Mills, Annaghdown, on a co-operative basis" to service the local farmers.

[12] In 1953 the ESB had its local headquarters at the mill for the Rural Electrification scheme, with the notice stating that 325 houses in the area were ready for wiring.

In 2014 Cregg Mill and cottage were advertised for sale, with the advertisement noting that the property comprised three individual residential units (the mill, the former miller's cottage, and an apartment) totalling 1,114.8 m2 (12,000 sq ft), with 27 rooms in total including a top floor loft style gallery of 139.35 m2 (1,500.0 sq ft).
