That annotation survives on the Down Survey parish map of Mucully and part of Desert Parish, surveyed between 1655 and 1656, where the cartographer placed a small drawn house beside a watermill in a townland recorded as Galstowne, now Gaulstown, in County Kilkenny.

The Down Survey was a vast Cromwellian mapping project, carried out in the mid-1650s to catalogue Irish land in preparation for redistribution after conquest. Each map came with a written terrier, a supporting document that recorded landholdings in plain text alongside the visual survey. The terrier for this area names the proprietor of the Gaulstown mill as Henry Archer, described as an "Irish papist", the standard designation applied at the time to Catholic landowners, whose properties were under scrutiny or threat of confiscation. The mill sat on the north bank of the Douglas River, at a point where three townlands converge: Muckalee to the west, Drumerhin to the south, and Gaulstown itself. Watermills by their nature required a reliable flow, and the junction of townland boundaries on a riverbank often marks a long-contested or carefully shared resource. Nothing above ground is known to survive, and the riverbank at this location is today heavily tree-covered, the kind of dense riparian growth that tends to colonise sites where stone and earthwork have gradually given way to vegetation over centuries.
