The cylinder case, list, and the cylinders' holders were the first clues that these were the lost Francis O'Neill Cylinders. The initials next to the tune names on the list indicate the musician recorded: T for Patsy Touhey, McF for John McFadden, C for Edward Cronin, E for James Early, and D for Bernard Delaney.
The case was designed to hold thirty-six cylinders; three of the cylinders found in the case were commercial cylinders and one (labeled as "Stack of Barley") was a blank cylinder.
Tune names for the publication versions of the cylinders were based on the spoken introductions on the cylinders or the written documentation included with the cylinders. When these were not available, titles found in Francis O'Neill's publications were used when possible.
