Greene’s father was a prosperous Dorchester merchant, who rose to the rank of capital burgess in the borough corporation. His friends included the town’s puritan rector, John White, and the prominent lawyer Francis Ashley*.
Greene was actually serving as one of Weymouth’s bailiffs in December 1620 when he was elected to represent the borough in the 1621 Parliament. Accordingly, he not only signed his own return, but may also have helped secure another seat there for Christopher Earle, his colleague in King’s Bench.
In 1623 Greene’s claims to gentility were rejected during the heralds’ visitation of Dorset, perhaps partly because of his mercantile activities.
In around 1624 Greene was employed to defend the claim of Sir Thomas Myddelton II* to the royalties of Ruthin, Denbighshire, and presumably he backed Myddelton during the Weymouth by-election in May that year. Myddelton initially retained his seat in 1625, but when he opted to represent Denbighshire instead, Greene filled the Weymouth vacancy. He apparently met with some local objections, for on 4 Aug., prior to his election, he was bound in £100 to do the borough good service without requiring wages.
Greene was selected in late 1625 to contribute to the Privy Seal loan, but was then excused payment in the following March.
In February 1627 Greene was appointed to help record prize goods brought into Weymouth, while seven months later he was selected to inquire into the funds originally raised for the Algiers expedition of 1620-1. That suggests that his criticism of Buckingham had not caused lasting offence. At this juncture Greene was still occasionally trading at Weymouth.
In the aftermath of the 1629 session, Greene visited the Tower in the hope of taking a message from Denzil Holles* to the latter’s wife, the daughter of Francis Ashley. Despite this apparent show of sympathy for a prominent opponent of the Crown, Greene was on friendly terms in the early 1630s with Edward Nicholas*, Buckingham’s former secretary, and he successfully obtained a surveyorship in the new salt manufacturing monopoly granted in 1636.
