A good story bears retelling, and the one about the family Kennedy is among the best. It has the elements and sweep of 19th century literature: great expectations, war and peace and, in recent years, the whiff of a cherry orchard. In their 1984 book The Kennedys, Peter Collier and David Horowitz describe a Thanksgiving at Hyannis that had taken place two years before. After dinner, Rose, then 93, gathered her strength to address the remnants of her tribe. "I want you all to remember," said the frail matriarch, "that you are not just Kennedys, you are Fitzgeralds too."
