At Dromahaire Abbey, in County Leitrim, many years ago there was a man saying his prayers in a part of the sacred enclosure. It is said that, when he rose from his knees, he took an iron spoon that lay under a slab covering a grave and put his hand into a hole up to the shoulder and drew up a spoonful of the clay. This he wrapped up in paper and told people it was for a sick person who subsequently mixed it in water, and he drank it for a remedy. he declared that this was the grave of Father Peter and that he had been a very holy man.
ARDMORE
There are many legends and superstitions that surround these beautiful ruins of Ardmore Abbey and its round tower. It was said to be Saint Declan who founded the original abbey and its tower, building the base course in one night, while on the second night he built it up to its second level, carrying it to the third level on the third night. But an angry old woman scolded the saint and asked, “Will you never be done?” Saint Declan immediately completed the final part of the structure finishing it off with a conical cap.

It was also said that Declan went on a pilgrimage to Rome, and on his return, as his ship approached Ardmore some gigantic pagans tried to prevent his landing and ran out to sea threatening him. But Declan transformed them into rocks, and they stand there to this day, forming a reef. At this time also, it is reported, that a large glacial boulder floated behind Declan’s ship all the way from Rome. It followed in the ship’s wake and lodged itself safely on a ridge near the ship and cried out, “The clerk forgot the bell,” whereupon they found the bell and his vestments on the rock although they had been left behind in Rome. The stone lies there until this day, resting upon an outcrop of local rocks on the shore, and it is said to work miraculous cures to those who rub their backs against it, or creep under it in the hollow between two supporting rocks. There is a warning, also, that anyone attempting to gain a cure with a stolen garment or having unabsolved sins on their soul will have the stone press down upon them and prevents their passage through.
At Ardmore, County Waterford, in the churchyard of the ancient and most interesting ruined abbey, they show the spot where it was said Saint Declan, the founder, was buried. It is walled around, but inside the soil has been excavated to a considerable depth in past times and the custodian of the place was selling the earth as a cure for sick people.

Also, in the graveyard the practice of creeping beneath stones is seen when a childless woman creeps under a tombstone in their quest to become mothers. (from ‘Notes on Irish Folklore’, Folklore vol.27, No.4, 1916, pp419-426: JSTOR, www.jstor.org/stable/ 1255596)
