He left his second wife Susannah Elizabeth a life interest in the Ford estate, after which it was to pass to his granddaughter Susan, and bequeathed his estates of Seaton Delaval and Doddington to his brother Edward Hussey Delaval (1729-1814). On the death of Edward in 1814, Doddington passed to Edward's wife and then to his daughter Sarah. Seaton Delaval passed to Jacob, the son of his deceased sister Rhoda, who had been married to Sir Edward Astley of Melton Constable in Norfolk.
