The Cailleach Bheur lives in the Highlands of Scotland. She is seen as a seasonal deity or spirit, ruling the winter months between Samhainn (1 November or first day of winter) and Bealltainn (1 May or first day of summer). She carries a hammer for shaping the hills and valleys, and is said to be the mother of all the goddesses and gods. The Cailleach displays several traits befitting the personification of Winter: she herds deer, she fights Spring, and her staff freezes the ground.
The family bloodlines of the Tuatha Dé Danann as they come to us from mythology, and there are many stories their relationships can be confusing. I'm not altogether certain about this family tree, there seems to be some inconsistencies...!!!
