In some cases, families have been apprised of an approaching death by some strange spectre, either male or female, a remarkable instance of which occurs in the MS. memoirs of Lady Fanshaw, and is to this effect: "Her husband, Sir Richard, and she, chanced, during their abode in Ireland, to visit a friend, who resided in his ancient baronial castle surrounded with a moat. At midnight she was awakened by a ghastly and supernatural scream, and, looking out of bed, beheld by the moonlight a female face and part of the form hovering at the window. The face was that of a young and rather handsome woman, but pale; and the hair, which was reddish, was loose and dishevelled. This apparition continued to exhibit itself for some time, and then vanished with two shrieks, similar to that which had at first excited Lady Fanshaw's attention. In the morning, with infinite terror, she communicated to her host what had happened, and found him prepared not only to credit, but to account for, what had happened.
"A near relation of mine," said he, "expired last night in the castle. Before such an event happens in this family and castle, the female spectre whom you have seen is always visible. She is believed to be the spirit of a woman of inferior rank, whom one of my ancestors degraded himself by marrying, and whom afterwards, to expiate the dishonour done his family, he caused to be drowned in the castle moat."
This, of course, was no other than the Banshee, which in times past has been the source of so much terror in Ireland. Amongst the innumerable stories told of its appearance may be mentioned one related by Mrs. Lefanu, the niece of Sheridan, in the memoirs of her grandmother, Mrs. Frances Sheridan. From this account we gather that Miss Elizabeth Sheridan was a firm believer in the Banshee, and firmly maintained that the one attached to the Sheridan family was distinctly heard lamenting beneath the windows of the family residence before the news arrived from France of Mrs. Frances Sheridan's death at Blois. She adds that a niece of Miss Sheridan's made her very angry by observing that as Mrs. Frances Sheridan was by birth a Chamberlaine, a family of English extraction, she had no right to the guardianship of an Irish fairy, and that therefore the Banshee must have made a mistake.
