[3] After the birth of her son, Arthur Twining Hadley III, in February 1945, her 18-month marriage ended in divorce in 1947.
[1][4] Hadley obtained employment in public relations, first working for cartoonist Al Capp and was described in a 1950 article in Look magazine as "the chic, high-level, in-the-know, celebrity-surrounded career girl that millions of young women dream of becoming in New York."
[8] After returning to America and marrying Smitter on 24 January 1953, she lived in South Africa, then in Jamaica, West Indies.
She co-wrote the 1966 book Manners for Young People with John Barclay, who gave dancing lessons to children at the Pierre Hotel.
In March 1978, for two months, she visited her daughter, Victoria Barlow, who was living in Dharamsala, India, where she had been studying Buddhism at the Library of Tibetan Works and Archives and in Manali, in meditation retreat.
The trip became the inspiration for her book A Journey with Elsa Cloud, which provided a fictionalized account of her own experiences.
[12] Caroline claimed that Henry "Hank" Luce III had repeatedly tried to rape her when she was a teenager, and had sexually abused her over a six-year span in the 1970s.
She also lived on Fishers Island, New York, where she is buried next to Henry Luce III at the Union Chapel.
She was survived by her eldest son, Dr. Arthur T. Hadley III, Matthew Eliott (who had changed his last name from Smitter in the 1970s), Caroline Smitter Nicholson, Victoria California Van Duzer Barlow, stepson Henry Christopher Luce, stepdaughter Lila Luce, and seven grandchildren.
