Churchill had several nervous breakdowns. In 1962, she began working with the Samaritans, an organisation created for the prevention of suicide.[8] On 20 October 1963, she died at 58 Chester Row, Westminster, S.W.1, leaving an estate valued at £59,259.[9] The cause of death was an overdose of barbiturates, and a coroner later concluded that it was a case of suicide.[8] She is buried with her parents (who both outlived her) and her siblings (Marigold originally was interred in a tomb at Kensal Green Cemetery in London, but her remains were relocated in 2019 to join the rest of her family) at St Martin's Church, Bladon, near Woodstock, Oxfordshire.
