The Kenney Curse refers to a series of unfortunate events that have happened to the famed Kennedy family. While these events could have happened to any family, some have referred to the continual misfortune of the Kennedy family as a curse. Several members of the Kennedy family have died from unnatural causes, most notably brothers John F. Kennedy and Robert F. Kennedy who were assassinated, and John F. Kennedy, Jr., who died in a 1999 plane crash.
