Lord Harcourt Sr. was the father of Rafe Harcourt. Lord Harcourt had a strained relationship with his son: Rafe felt controlled by him. He died himself at some point after October 2022. In May 2023, Rafe learned that he had inherited £35 million from his father, under the condition that he was married. In September 2023, Dilly took it upon herself to plan the Harcourts' first charity bonfire night since her father-in-law's death.
