The pilot episode took place in winter 1961. In the pilot episode, Nick, a millionaire, who adopts six orphaned girls. The sixth girl is Nina, who appears in the pilot episode, was written out of the show explaining that Nina reunited with her birth mother. I remember the series finale ended, where it took place during the Cuban Missile Crisis in October 1962, when Diane celebrates her sweet 16th birthday party. It started when I was six years old and a kindergartner and it ended when I was seven years old and a first grader in grade school.
