Kiltrustan is near Strokestown, Co. Roscommon. The account of the sighting of the Black Pig also corresponds with some traditional fairy lore: "Crowds, full of awe, are visiting the place and the children of the parish are in a state of terror. Two men who cut a tree on an old rath or fort are ill, and many attribute their illness to the appearance of the pig."
