19th century Ireland produced a proliferation of 'Oirish' literature and poetry claiming to be 'folklore', but which was in fact extremely patronising, and having nothing whatever to do with 'the folk' - to me, this sounds suspiciously like such a piece.
It spilled over into the 20th c. with many Hollywood production abounding with 'quaint' but somewhat 't'ick' Paddies, a prime example being 'Darby O'Gill and the Little People'.
There are plenty of examples of the genuine article; in 1991, Irish folklore journal Béaloideas devoted a whole edition to the subject entitled 'The Fairy Hill is on Fire'; well worth seeking out.
