At Bryanmore in County Westmeath, one such annotation appears: the words "Lady Well", picked out in that distinctive lettering on the 1837 edition of the six-inch map. The name alone carries considerable weight. Lady Wells, traditionally dedicated to the Virgin Mary, were a fixture of pre-Reformation and post-Reformation devotional life across Ireland, often serving as sites of patterns, the communal gatherings combining prayer, pilgrimage, and socialising that took place on a saint's feast day or other appointed date.

The qualification "possible holy well" is telling. Holy wells in Ireland vary enormously in their physical form, from elaborately enclosed stone structures with carved niches and votive offerings to little more than a damp hollow in a field that locals once held sacred. Some have been lost entirely, their precise location forgotten, their waters absorbed into drainage works or simply dried up over time. At Bryanmore, the cartographic evidence from 1837 is the clearest record that survives, suggesting the site was recognised in the early nineteenth century even if its current condition or exact location on the ground remains uncertain. The gothic script convention used by the Ordnance Survey was not applied casually; surveyors reserved it for antiquities and places of established local note, which implies the well had a genuine presence in the community's memory at the time of mapping.
