Marylou Whitney
Who
The widow of Cornelius "Sonny" Vanderbilt Whitney, Marylou Whitney inherited an estimated $100 million when her husband died in 1992. A social staple, philanthropist, and horse aficionado, Marylou now has a husband who could easily pass for her grandson: She remarried tennis pro John Hendrickson in 1997 when she was 71 and he was 32.
