What makes the site quietly unusual is not just that bones were found, but that each discovery sparked just enough official interest to produce a file note and a few artefacts before the trail went cold, leaving the site essentially unexamined and its origins still a matter of inference rather than fact.

The first discovery came in July 1941, when substantial quantities of human remains were reportedly turned up. Two hones, one of them perforated, and a bone pin were recovered and assigned National Museum of Ireland accession numbers (1941:725, 726, and 727). The archaeologist Joseph Raftery visited, but the landowner refused permission for any excavation, and the matter rested there. Then in June 1955, a second report reached the National Museum: more remains had been found in the same sandpit, this time lying just beneath the topsoil at around 0.2 metres deep. The man who reported it was Michael Dwyer, a local who had previously worked on excavations with Professor Seán P. Ó Ríordáin at the important nearby prehistoric complex of Lough Gur. Dwyer sent a small quantity of bone, along with charcoal and iron slag, to the museum, and in his accompanying letter he described and sketched two distinct layers of bone visible in section through the mound, at depths ranging from roughly 0.23 to 0.61 metres. Cahill and Sikora, writing in 2011, noted that the location, the finds, and the associated sites in the area suggest the burial ground has its origins at least in the early medieval period, broadly the fifth to twelfth centuries, and may once have been connected to a nearby settlement.

Bohergar lies close to Caherconlish in east County Limerick, and the site has not been formally excavated in the decades since Dwyer's letter. The iron slag is a detail worth pausing on: its presence alongside human remains can indicate proximity to early medieval craft activity, though without proper investigation it remains suggestive rather than conclusive. Visitors to the area will find no marker or formal access; the site's significance exists largely in museum records and a hand-sketched letter from a man who knew enough to recognise what he was looking at.
