Marie Laveau

Marie Catherine Laveau (September 10, 1801 – June 15, 1881) was a Louisiana practitioner of voodoo, herbalism and midwifery. She was well-known in 19th century New Orleans. 
Her daughter, Marie Laveau II, (1827–c. 1862) also practiced rootwork, conjure, Native American and African spiritualism and Louisiana voodoo.
An alternate spelling of her name, Laveaux, may be from the original French spelling.
