Wirt Sikes, British Goblins: Welsh Folk-lore…
“ I find no resemblance in the Welsh fairy to our familiar mermaid, beyond the watery abode, and the sometimes winning ways. The Gwragedd Annwn are not fishy of aspect, nor do they dwell in the sea. Their haunt is the lakes and rivers, but especially the wild and lonely lakes upon the mountain heights. These romantic sheets are surrounded with numberless superstitions, which will be further treated of. In the realm of faerie they serve as avenues of communication between this world and the lower one of annwn, the shadowy domain presided over by Gwyn ap Nudd, king of the fairies. ”
