Coventry’s paternal grandfather was a distinguished judge under Elizabeth and James, while his father was a prominent London lawyer, who became attorney-general in 1621. In 1623 Coventry was specially admitted to the Inner Temple, where his father was then serving as treasurer. The latter took considerable pains over his son’s marriage. According to Sir Simonds D’Ewes†, he initially considered marrying his son to Anne Clopton, but he lost interest on realizing that his prospective daughter-in-law would not gain control of her inheritance until after her stepmother’s death.
Coventry was too young in 1621 to replace his father as Member for Droitwich when the latter was obliged to surrender his seat. He first sat for the borough in 1625, but made no impression on the surviving records. He was re-elected in 1626, when he was named to a conference with the Lords on 7 Mar. to discuss preparations for war.
In 1634 Coventry’s wife died in childbirth. According to a contemporary newsletter, her brother-in-law, (Sir) Percy Herbert*, tried to bring a Catholic priest into her bedchamber ‘to have perverted her religion in her greatest extremity’. It seems unlikely that Coventry himself was then present, as it was left to his father’s purse-bearer to prevent Herbert and the priest from entering ‘by main force’.
Coventry succeeded his father in January 1640. He initially supported the king but made his peace with Parliament in October 1642.
