Jay’s family may have originated in Dorset, where his father had property in Cranborne.
Jay matriculated at his father’s Oxford college before progressing to Lincoln’s Inn. Once in London he behaved with reckless abandon, marrying a widow within a few months. His father so disapproved of this match that he terminated his son’s £60 annuity, obliging Jay to live off his wife’s maintenance. Jay found lodgings at a scrivener’s in Fleet Street where his landlord’s servant, Thomas Coke, sold him a watch and sword for £20. As Jay later claimed that these items were ‘not worth above 90s.’ it seems likely that this transaction was actually a disguised usurious loan. At any rate, Jay’s desperate financial condition meant that he was in no condition to pay Coke, or to meet his obligations in the form of bonds and counter-bonds amounting to £200 which had been taken out to guarantee his debt. In frustration, Jay took his case to Chancery, where he claimed to have been swindled. By the end of his first year in London, Jay’s total debts amounted to above £700. His father agreed to pay these on the condition that Jay and his new wife return to live with him at Fittleton ‘in hope of his reformation and to try if he could to draw him into a better course of life’.
At Fittleton, Jay continued to lead a life ‘of excess and great expense’. In his will of April 1623 Jay’s father, fearing the waste of an estate comprising three manors and £3,000 in goods, stipulated that his son should receive only a life annuity of £80.
Jay’s inheritance, although diminished, sufficed to procure him both a knighthood and elevation to the county bench in 1625.
Jay had an address at Blackfriars by 1627, and his involvement in the Île de Ré expedition during the summer, when he travelled to France, perhaps suggests that he held a minor office in the Armoury at this time.
Jay’s later life remains obscure. He was granted livery of seisin of lands in February 1638, but died the following year. Neither will nor letters of administration have been found.
