Okehurst’s family had probably held land at Oakhurst in the parish of Billingshurst in west Sussex for several generations before 1397, when John, father of our MP, did homage to the bishop of Chichester for lands at Ham in Sidlesham, to the south of the city. A lawyer, John built up the family’s landed holdings in the Arun valley, and he associated William with him in transactions relating to them in 1400. William would appear to have inherited his father’s lands by 1414, and three years later his brother John formally quitclaimed to him certain properties in Rudgwick. In April 1419 he received from his mother Cecily, who by then had married William Walton, her life-interest in the manor of Ham, in return for an annual payment of £4.
From an early point in his career Okehurst was closely attached to Thomas Fitzalan, earl of Arundel, in whose retinue he served on Henry V’s first campaign in France in 1415. The previous year, Earl Thomas had granted him for life the Sussex manor of Nutbourne, and in his will (made after his voyage home from the siege of Harfleur), he left him an annuity of £5. Clearly, Okehurst had been regarded warmly by his lord.
Meanwhile, in 1428 Okehurst had been asked to execute the will of Sir John Wiltshire, who had himself been named as an executor of the late earl of Arundel,
Okehurst acquired other landed interests in his native county during the course of his career, including property in the Pallant and East Street in Chichester.
It would appear that Okehurst had a son named William, who predeceased him before July 1448. It was then that the MP arranged the marriage of his grand-daughter and heiress, Elizabeth, to Thomas Bartelot, the son of his friend John, and was party to the settlement on the couple of lands in Sullington and Storrington. Accordingly, it was to the Bartelots that his manor of Ham passed after his death.
