A New York Times obituary for C. Wyatt described Nancy and C. Wyatt as “wealthy bons vivants who witnessed history over candlelight at dinner parties, inaugural balls, and even 1970s discotheques.”
Nancy passed away first, in 1997, due to complications from a stroke. She’s buried at Arlington National Cemetery next to her second husband, former Navy commander John C. Whitehead, whom she married in 1989.
