Carrie C. White ("née" Joyner; August 1888 – February 14, 1991) was an American woman whom "Guinness World Records" recognized as the oldest person in the world in 1988, the year she allegedly turned 114.
 This claim was based on documents from the Florida State Hospital, where she was institutionalized from 1909 to 1984, that listed her birthdate as November 18, 1874.
