Madeleine Duncan Brown (July 5, 1925 – June 22, 2002) was an American woman who claimed to be a longtime mistress of United States President Lyndon B. Johnson. In addition to claiming that a son was born out of that relationship, Brown also implicated Johnson in a conspiracy to assassinate President John F. Kennedy. According to Brown, she was raised in a middle-class Catholic household in Dallas, Texas, where her father was a utility company supervisor and her mother was a housewife. was referred to in newspaper reports about the suit as "Jess C. Kellam". Tilson indicated that close associates of the Johnson family were not familiar with the name "Steven Mark Brown" nor was there any record of correspondence or visitation from him within the Lyndon Baines Johnson Library and Museum. Haun wrote that literary agent Scott Meredith had been enlisted to handle the book and film rights. He died in 1990, at age 39, In 1988, she briefly appeared in investigative columnist Jack Anderson's syndicated program, American Expose: Who Murdered JFK, and said: "In the fall of 1963 I was in the Carousel Club with other advertising people, and Jack Ruby was saying that Lee Harvey Oswald had been in the club and he had been bragging that he had taken a shot at Major General Edwin Walker".

Brown said that on New Year's Eve 1963, she met with Lyndon Johnson at the Driskill Hotel in Austin, Texas, and that Johnson confirmed the conspiracy to kill Kennedy, insisting that "Texas oil and ... renegade intelligence bastards in Washington" had been responsible. Brown alleged that Johnson did not attempt to stop the assassination because he hated Kennedy and had an intense desire to be President.

According to Perry, he and his wife met Brown at a social function a few years after she made her original allegations as to the JFK assassination but did not find her story to be believable. The conviction was overturned in 1994 when the appeals court determined she had not personally signed the original will. That suit was dismissed due to lack of evidence.
