The famous Lake Maidens of Wales, their name means ‘Otherwordly women’. While many fairies who make their homes in bodies of water are at best mercurial and at worst murderous, the Gwragedd Annwn have a good reputation for kindness and gentle ways. They appear as beautiful young women and are known to make good wives when they marry human men, although like many fairy wives they usually leave if the man violates a taboo relating to them.
In many stories of these Lake Maidens this taboo has to do with the husband striking the wife three times. Even if they are forced to leave their family such fairy women stay involved with their children, and one Welsh family renowned for their medical knowledge claimed it had come from a long-distant Gwragedd Annwn ancestor. The Gwragedd Annwn are strongly associated with cattle, both Earthly cows and Otherworldy ones, which may be seen as symbols of abundance and blessing.
