The stone, a flag just eight inches square, was unearthed along with pieces of cut-stone at Garranamanagh, and recorded by the historian William Carrigan in 1905. By the time he wrote it up, it had already vanished. He noted its dimensions and the fact of its inscription, and then had to admit that its whereabouts could not be traced. It has not come to light since.

The site where the stone was found sits within an enclosure that may once have been a grange, an outlying farm or estate managed by a religious house, in this case possibly Jerpoint Abbey. Jerpoint, a Cistercian foundation a few kilometres away near Thomastown, was one of the most significant monasteries in medieval Leinster, and its network of agricultural lands stretched across the surrounding countryside. Granges were working parts of that economy, managed by lay brothers and producing food and income for the community. The cut-stone fragments found alongside the inscribed flag suggest some kind of built structure once stood here, though nothing in the surviving record explains what the inscription contained, who placed it, or what the structure was for. The stone was small enough to be easily moved or reused, which may explain why it disappeared so completely.
