Kathleen Agnes Cavendish, Marchioness of Hartington was an American socialite. She was the fourth child and second daughter of Joseph P. Kennedy, Sr. and Rose Fitzgerald.
Kathleen was Marchioness Of Hartington, 
when Kathleen came to London with her father, she met a wealthy, titled aristocrat. He was William Cavendish, the Marquess of Hartington — the powerful 10th Duke of Devonshire's son and heir not only to the title, but to the palatial Chatsworth House estate, among other rich properties. He was such a catch that the British royal family apparently had their eye on him for their own Princess Elizabeth, the future queen.
Kathleen, nicknamed "Kick," married Billy, as he was called, when she was 24, on May 6, 1944. A World War II romance, they were very much in love-despite their different faiths, which raised great conflict within their families: His family, for hundreds of generations, was very much Church of England, and hers was devout Roman Catholic. In fact, Rose Kennedy noted that she was "disturbed, horrified, heartbroken" that her daughter Kathleen had married a Protestant — and in a civil ceremony at that (Kathleen's brother, Joseph, was the only family member to attend). Rose didn't have contact with her for nearly two months after the wedding.

Today, visitors can see the tiny Protestant churchyard in the charming village where Kathleen is buried in the Cavendish family plot, with a plaque by her gravestone noting the June 1963 visit of JFK just months before his own death. And, about a mile away, is Chatsworth House, the gorgeous 297-room estate where, prior to her marriage, Kathleen had celebrated her 24th birthday.
