Having seemingly found peace and contentment after years marked by turmoil, Jackie's death from non-Hodgkins lymphoma in 1994 at the age of 64 was all the more heart-rending.

Red Gate Farm passed to her daughter Caroline, who eventually put it up for sale with Christie's International Real Estate in 2019 for $65 million (£49m).

A year later, it was partially sold to two land conservation agencies for $27 million (£20.7m). The Martha Vineyard's Land Bank Commission then purchased a further 32 acres (13ha) for $10 million (£7.6m) in 2021, with Caroline retaining 95 acres (38ha), including the main residence, guesthouse and three-bedroom caretaker's house.
