No stone, no mound, no marker. Yet this was, within living memory, the location of a small but deliberate memorial: a grave mound ringed by upright stones, like a miniature version of the kind of kerbed cairns found elsewhere in Ireland, with two whitethorn trees planted roughly two and a half metres apart to mark the spot.

The place was recorded in 1934 by Bowman, who noted it as the burial site of two Catholic priests martyred during the Penal Laws, the series of statutes enacted from the late seventeenth century onwards that severely restricted Catholic worship, education, and land ownership in Ireland. Priests who continued to minister during this period did so at considerable personal risk, and clandestine Mass sites in remote valleys were not unusual. The name of the valley itself, Gleanntan an Aifrinn, quietly records that history. By around 1910, the mound and its circle of stones were still present, though the site had never been marked on the Ordnance Survey six-inch maps of either 1842 or 1904, which suggests it was maintained through local knowledge and quiet observance rather than any official recognition. One of the two whitethorn trees survived into the 1980s, and was apparently removed around 1985. After that, nothing remained above ground to indicate the site existed at all.
