Step 1 : Introduction to the question "Who is the only U.S. President whose grandmother outlived him?"
John F. Kennedy's grandmother not only outlived him, but was never told about her grandson's assassination. John F. Kennedy's grandmother died at the age of 98 without learning that her grandson, the late President John F. Kennedy, had been assassinated. The tragic news of the late President’s death had been kept from her by relatives who feared the shock might kill her. Mrs. Josephine Mary Hannon Fitzgerald, maternal grandmother of President Kennedy was the widow of John F. Fitzgerald, former Mayor of Boston.
