She was traveling with Peter Wentworth-Fitzwilliam, the eighth Earl Fitzwilliam, with whom later biographies describe her as being romantically involved and hoping to marry. The aircraft encountered heavy rain, turbulence, and strong winds; all four people aboard were killed.
Although she is widely remembered as “Kick Kennedy,” her name at the time of her death was Kathleen Cavendish, Marchioness of Hartington. She was John F. Kennedy’s sister—not his wife—and her death came after a brief marriage, widowhood, and a relationship that crossed both religious and social boundaries.
Who was Kick Kennedy?
Kathleen Agnes Kennedy was born on February 20, 1920, in Brookline, Massachusetts. Known within her family and to the public as “Kick,” she was the fourth child and second daughter of Joseph P. Kennedy Sr. and Rose Kennedy. Her older brother Joseph P. Kennedy Jr. and younger brother John F. Kennedy would also become central figures in the family’s public history.
Kick’s life changed when her father became the United States ambassador to Great Britain in 1938. The Kennedy family moved to England, and the young American ambassador’s daughter quickly became a prominent figure in London society. She later worked for the Washington, D.C., Times-Herald and returned to Britain during the Second World War as a Red Cross volunteer.
#1 Best Overall
Her position gave her access to British political and aristocratic circles, but it also placed her Catholic family within a society governed by different religious and class expectations. Those tensions shaped both of her major relationships.
Her marriage to William Cavendish
On May 6, 1944, Kick married William “Billy” Cavendish, Marquess of Hartington. Cavendish was the Protestant heir to the Cavendish family and the son of the Duke of Devonshire. The marriage crossed the religious expectations of Kick’s Catholic family and connected her to one of Britain’s most prominent aristocratic houses.
The marriage lasted only a few months. Cavendish was killed in combat in Belgium on September 10, 1944. Kick became a young widow while still in her twenties, but she remained in England and continued moving within British aristocratic and political circles.
Because she had married into the Cavendish family, Kick’s formal title at the time of her death was Marchioness of Hartington. “Kick Kennedy” remains the most recognizable name for biographical purposes, but “Lady Hartington” or “Kathleen Cavendish” is more precise when describing her final years.
Who was Peter Fitzwilliam?
After her husband’s death, Kick became romantically involved with Peter Wentworth-Fitzwilliam, the eighth Earl Fitzwilliam. Later biographies and archival commentary describe him as her lover and, in some accounts, her fiancé. The pair were reportedly planning to marry if circumstances—including Fitzwilliam’s existing marriage and the objections of Kick’s Catholic family—could be resolved.
The exact status of their relationship needs careful wording. A 2008 John F. Kennedy Presidential Library and Museum forum transcript says that Kick and Fitzwilliam were traveling to Paris in an effort to obtain Joseph Kennedy Sr.’s approval. Some later biographies describe Fitzwilliam as her fiancé, while other accounts are more cautious. It is safest to say that they were a romantic couple who intended to marry if circumstances permitted, rather than treat a formal engagement as an uncontested fact.
Contemporary newspaper reports were also more discreet than many later biographies. They did not always identify Fitzwilliam as Kick’s romantic partner. The phrase “with her lover” reflects the later historical and biographical record, but it should not be mistaken for the language used in every contemporary account.
The final flight on May 13, 1948
On May 13, 1948, Kick and Fitzwilliam boarded a chartered de Havilland DH.104 Dove. This was not a scheduled commercial airline flight. It was a non-scheduled charter flight that departed from Croydon, traveled to Paris, and then continued toward Cannes on the French Riviera.

At approximately 5:30 p.m. local time, the aircraft crashed near Saint-Bauzile in the Ardèche region of southern France. Accounts place the wreck in or near the mountainous Plateau du Coiron area, also referred to in some descriptions as Mont Le Coran. All four occupants died.
What caused the crash?
The available crash-record summary identifies difficult weather conditions before the loss of control: heavy rain, turbulence, and strong winds. The mountainous terrain and poor visibility made the flight especially hazardous. The documented account supports describing the crash as a weather-related loss of control, not as a confirmed act of sabotage or a mysterious disappearance.
Rank #3
Later biographies and retrospective reports add a frequently repeated detail: the pilot allegedly advised delaying the flight because of the storm, and Fitzwilliam supposedly insisted that they continue. That story may derive from testimony or biographical reporting, but it should not be presented as an independently established official finding without consulting the underlying source directly.
A careful summary is therefore: later biographies reported that the party proceeded despite warnings to wait and that the aircraft then encountered severe weather. It is less responsible to state as proven fact that Fitzwilliam personally overruled the pilot.

No. The crash occurred in France, near Saint-Bauzile in Ardèche. Confusion may arise because Kick’s first husband, William Cavendish, was killed in Belgium during the Second World War. Those are separate events: Cavendish died in combat in Belgium in 1944, while Kick died in a plane crash in southern France in 1948.
Why was Kick traveling to France?
The flight had a practical travel destination: Paris and then Cannes. Later accounts also connect the Paris stop with Kick and Fitzwilliam’s reported attempt to secure Joseph Kennedy Sr.’s approval for their relationship or possible marriage.
That family-approval story is supported by later accounts and by a Kennedy Library forum transcript, but it should not be presented as the flight’s sole or definitively documented purpose. The itinerary itself included travel toward the French Riviera, and the evidence does not justify reducing the journey to one simple motive.
Where was Kick Kennedy buried?
Kick was buried in the Cavendish family burial grounds at St. Peter’s Church in Edensor, near Chatsworth, England. Her burial reflected her status as a member of the Cavendish family despite her American origins and her continued public identification with the Kennedys.

Her death compounded a series of tragedies for the Kennedy family. Her husband had died in wartime combat, and her older brother Joseph P. Kennedy Jr. had been killed during the Second World War. In 1957, Kick’s parents and siblings dedicated a physical-education building in her honor at Manhattanville College.
Did Kick Kennedy’s death prove a “Kennedy curse”?
The “Kennedy curse” is a later cultural interpretation, not an explanation for the crash. Kick’s death followed a chain of unusually painful family losses, which helped make the phrase compelling in popular memory. But there is no historical basis for treating a supernatural curse as the cause of the 1948 accident.
The evidence points to a specific aviation tragedy: a charter aircraft flying in severe weather crashed in the mountainous Ardèche region, killing everyone aboard. The family mythology grew afterward.
Further reading
Short institutional biographies establish the basic chronology, but later biographies provide much more detail about Kick’s London life, marriage, widowhood, relationship with Fitzwilliam, and death. Kick Kennedy: The Charmed Life and Tragic Death of the Favorite Kennedy Daughter by Barbara Leaming is a focused Kick Kennedy biography that the publisher describes as drawing on firsthand accounts, conversations with key participants, and previously unseen sources. It is a biography—not an official accident-investigation report.
Readers particularly interested in Kick’s connection to the Cavendish family and Chatsworth may also compare Paula Byrne’s Kick: The True Story of JFK’s Sister and the Heir to Chatsworth. The two books offer different emphases, so consulting both can help separate the well-documented chronology from disputed or cautiously reported details surrounding the final trip.

The John F. Kennedy Presidential Library and Museum provides the core biographical facts: Kick’s identity, family connections, marriage, wartime loss, death date, location in France, and burial. The National Park Service offers additional public-history context about her life and marriage. A crash-specific aviation record supplies the aircraft type, route, occupants, approximate time, and weather circumstances, but it should not be described as a national accident-investigation report.
Best Value
Details about Kick’s relationship with Fitzwilliam, the reported marriage plans, and the alleged warning to delay the flight come primarily from later biographies, retrospective journalism, and archival commentary. Those details are historically important, but the strongest writing distinguishes documented facts from claims that depend on later sources.
