We named our daughter, Annwyn, from the King Arthur myth about his travels to Annwfn. I haven't found it on any name sites, but think that it is very pretty. In researching other 'Annwyns' in the world, I've only managed to find twelve. It doesn't seem to be a common name, probably because of it's meaning. I believe that 'Annwfn' refers to the 'otherworld' which many people would take to mean hell. But I'm not sure. Does anyone else know anything about the orgin of Annwyn or Annwfn?
