ネルソン・ロックフェラー
Happy and her husband divorced on April 1, 1963, for reasons "The New York Times" called "grievous mental anguish" and her former husband's lawyer classified as "irreconcilable differences". One month later – on May 4, 1963 – at the home of Laurance S. Rockefeller in Pocantico Hills, New York, Happy married Governor Nelson Rockefeller, who had taken office in 1959 and was eighteen years her senior. She had worked as a member of his office staff until her resignation in 1961. Nelson divorced his first wife, Mary Todhunter Clark, on March 16, 1962. Happy and Nelson Rockefeller had two sons together: Nelson Rockefeller Jr. (born 1964), and Mark Rockefeller (born 1967).
