In popular medieval legend, a White Lady is fabled to appear by day as well as by night in a house in which a family member is soon to die. According to The Nuttall Encyclopaedia, these spirits were regarded as the ghosts of deceased ancestresses.
Castle Huntly, Scotland, is said to be haunted by a young woman dressed in flowing white robes. There are various stories concerning her history, one of which is that she was a daughter of the Lyon family who occupied the castle in the 17th century. When her affair with a manservant was discovered she was banished to a tower on the battlements. Unable to endure her suffering, she threw herself to her death from the tower. The ghost of the White Lady has been seen a number of times over the years, often on the grounds surrounding the castle. She has also been seen in the room in which she was imprisoned.
