Maloney married Clifton Maloney, a millionaire investment banker, in 1976. The couple had two daughters, Christina and Virginia. Her husband, who ran the New York City Marathon 20 times, was believed to be, at the time, the oldest American ever to summit an eight-thousander, the world's 14 mountains that surpass 8,000 meters in altitude. He died on a climbing expedition on September 25, 2009, after descending over 4,000 feet from the summit of the world's sixth-tallest peak, Cho Oyu in Tibet. Saying, I've just climbed a beautiful peak, these were apparently his last words as he went back to sleep and never woke up. Maloney is a member of The Junior League of the City of New York.
