Biographer Kitty Kelley's new book, "The Family: The Real Story of the Bush Dynasty," hits newstands today. Profiling three generations of the powerhouse political Bush family -- Sen. Prescott Bush, his son George Herbert Walker Bush and his son President George W. Bush -- the book is more about current events than family history, but there is some interesting insight into the characters and stories which make up the Bush family tree, including Flora Sheldon and Samuel Prescott Bush, the great, great, great grandparents of President George W. Bush.
