'The Kennedy Curse' Strikes Again With Death of Mary Kennedy, A Timeline Of Family History And Misfortune

The death of Mary Richardson Kennedy, an apparent suicide, is another instance to add to the timeline of the Kennedy family history, which many believe is under a curse of misfortune.

Richardson Kennedy, the estranged wife of Robert F. Kennedy Jr., was found dead on Wednesday in what police called an apparent suicide.

Despite their political fame and fortune, the family has been ridden with tragedy for decades, even years before the late-former President John F. Kennedy was assassinated in 1963. After this event, and the death of Robert Kennedy five years later, many began to believe the Kennedy family was under some sort of ominous curse, causing its members to die young from illness, assassinations and accidents, once they delved deeper into the history. Some even say troubles for the Kennedy family, an Irish-American clan originally from Massachusetts, began when the patriarch and father-of-nine Joseph Kennedy became an ambassador to Britain in 1937.
