I find historical photos fascinating, and this image in the Sargent Shriver slideshow got me wondering how many of these "third generation" Kennedys are still alive. A Wikipedia family tree reveals the answer: three (Ethel Kennedy, Jean Kennedy Smith and Joan Bennett Kennedy).
Sargent Shriver served as a campaign coordinator for John F. Kennedy. Here, President-elect John F. Kennedy, center, is surrounded by members of his family in the living room of the home of Joseph P. Kennedy, John's father, on Nov. 9, 1960. Standing, left to right: Ethel Kennedy; Steve Smith and wife, Jean Kennedy; Senator Kennedy; brother Robert Kennedy, campaign manager; sister, Patricia Lawford; Shriver; brother Ted's wife, Joan; and British actor Peter Lawford. In the foreground, seated are: sister, Eunice Shriver, left; mother Rose Kennedy; father, Joseph; Jacqueline Kennedy, wife of John and his brother, Ted Kennedy
