In Grant's later years, his lover, the poet Paul Roche (1916–2007), whom he had known since 1946, took care of him and enabled Grant to maintain his accustomed way of life at Charleston for many years. Grant and Roche's relationship was strong and lasted even during Roche's marriage and five children he had by the late 1950s. Roche was made co-heir of Grant's estate. Grant eventually died in Roche's home in 1978
