Jane Clark died in 1976. Her death was expected, but left Clark devastated. Several of his female friends hoped that he would marry them. His closest female friend, across many years, was Janet Stone, wife of the engraver Reynolds Stone; in common with Clark's daughter and sons, she was dismayed when he announced his intention to marry Nolwen de Janzé-Rice (1924–1989), daughter of Frederic and Alice de Janzé. The family felt that Clark was acting precipitately in marrying someone he had not known well for very long, but the wedding took place in November 1977. Clark and his second wife remained together until his death.
