California, and often socialized with actress Judy Garland and her family. Garland gave birth to her son Joseph at the same hospital, and on the same day, Kennedy gave birth to her son Christopher. Patricia and Peter (who was a member of Frank Sinatra's "Rat Pack") held lavish parties at their Malibu mansion during the 1950s and early 1960s with guests such as Marilyn Monroe. The Lawford's mansion was a popular venue for the Kennedy brothers to meet with Monroe. The couple had four children, all born in Saint John's Health Center, Santa Monica: Christopher Lawford (1955-2018), Sydney Maleia Lawford (b. 1956), Victoria Francis Lawford (b. 1958), and Robin Elizabeth Lawford (b. 1961). Despite the glamorous persona Lawford presented, their relationship suffered strains as early as their brief engagement. Lawford had difficulty adjusting to Kennedy's steadfast Catholicism and her family's larger-than-life image. Kennedy could not tolerate Lawford's heavy drinking, extra-marital affairs, and gradual addiction to drugs. Shortly after her brother Jack's death in 1963, she filed for a legal separation, and the couple was officially divorced in February 1966. She never remarried. Later years After her divorce, Kennedy battled alcoholism, and suffered from tongue cancer. She worked with the John F. Kennedy Library and Museum, as well as with the National Center on Addiction, and was a founder of the National Committee for the Literary Arts, for which she arranged a series of author lectures and scholarships. Death Kennedy died of pneumonia at age of 82 on September 17, 2006, in her Manhattan home. She was buried in Southampton Cemetery.
