Mary Elizabeth McHughes Ferrell (26 October 1922 – 20 February 2004) was an American historian and independent researcher who created a large database on the John F. Kennedy assassination. Born in Memphis, Tennessee, she married Hubert Afton "Buck" Ferrell in 1940 and had four children. In 1957 the family moved to Dallas, Texas, where Ferrell found work as a legal secretary. She began collecting materials on the Kennedy assassination immediately after the event. Her assassination database was originally written on over 40,000 cards and included details of over 8,200 people involved in the case. These data were eventually entered into a computer. Ferrell also created a four-volume set of chronologies, covering all aspects of the assassination. More information...
