What they do carry are crosses cut in what observers have called an ancient pattern, the kind of decorative incised work that places them somewhere outside the ordinary run of datable memorial stones.

The slabs were recorded by William Carrigan in 1905, who noted them as "two uninscribed ones, with crosses of ancient pattern". Graveslabs of this type, flat or gently tapering stones marked with a simple incised cross rather than carved lettering, were common throughout medieval Ireland, often associated with ecclesiastical sites. Carrigan's brief description was revisited by Buggy in 1969, who found what are likely the same two pieces still present, describing them in almost identical terms. The near-verbatim repetition across more than sixty years says something about the slabs themselves: they had not moved, had not been identified more precisely, and remained stubbornly anonymous. Whether they are early medieval, later medieval, or something else entirely, no one has firmly established.
