It appears on Ordnance Survey six-inch maps from as far back as 1842, and again on the 1901 revision, each time marked plainly as a burial ground. By those designations alone, it has been known for the better part of two centuries. What it has not been, for much of that time, is visible. The ground is heavily overgrown, and only one possible headstone remains apparent to anyone who looks closely enough.

The site belongs to a category of burial ground that appears throughout rural Ireland, often without a church affiliation or a clear founding date, sometimes associated with early Christian communities, sometimes with the practice of burying unbaptised infants in unconsecrated ground, and sometimes simply with the accumulated habit of a local community over generations. At Farranamanagh, the historical record does not specify which of these it was. What it does confirm is continuity of recognition: the same field, the same function, mapped and noted across six decades of nineteenth-century surveying, and then watched over, however loosely, ever since.
