I live in Clifton Virginia. This tale was obtained from another website and is riddled with inaccuracies. However I think it makes a great Halloween ghost story so I am including it here with some grammar and spelling corrections.
The avenging spirit goes by many names: Bloody Mary, Bloody Bones, Hell Mary, Mary Worth, Mary Worthington, Mary Whales, XXXX XXXXXXX, XXXX Lou, Mary Jane, Sally, Kathy, Agnes, Black Agnes, Aggie, Svarte Madame.Summoning Mary requires the right chant. "I believe in Mary Worth" is the key phrase according to one version, but others require the shouting of "Kathy, come out!" or the repetition of "Bloody Mary" into the mirror as many times as the ritual demands. (Sometimes Bloody Mary gets more of a script and is summoned by calls of "Bloody Mary! I killed your baby!")
