No, Nymths are a pagan concept of fearies/fairys, that watched over nature with gaia herself. the image of the fearies with gauzy wings, and the look of a minature person wasnt given to fearies until around the 18th century, and the domination of the catholic religion almost whiped out totally the thought of nymths, fearies ect. for the simple reason that any wiccan (old english for witch) was burnt, as the catholic church wanted the country to be catholic, and to rid the country of the pagan religion.

Before then, and after the 18th century, beings like jack-o-lantern, and willo-the-whisps, where associated with fearies/fairies, even robin goodfellow, though given his father was 'king of the fairies'.
