Here is a link to the site for the Bell Witch Cave. The illustration to the left is of Betsy Bell, who with her father, John Bell, were tormented by "Kate." There appear to be a lot of references to the Bell Witch story available. Here is another account of the legend with emphasis on future president Andrew Jackson's visit to the farm; and the State of Tennessee also has a page, with clickable larger illustrations, about "America's greatest ghost story."
You can read the text from Martin Van Buren Ingram's 1894 "Authenticated History of the Bell Witch" online.
