Denne’s earliest known ancestor held lands in east Kent under John, and his son, Sir Alured, was seneschal of Christchurch Priory, Canterbury and escheator for Kent in 1234.
Shortly after attaining his majority, Denne underwent a legal training at the Inner Temple, culminating in his admission to the bar in June 1607. He may have received encouragement from another Thomas Denne, New Romney’s standing counsel and perhaps a kinsman.
Denne played little recorded part in the 1624 Parliament. On 25 Mar. he was nominated to the bill committee for the repeal and continuance of expiring statutes, and on 22 Apr. he reported a naturalization bill for the Norwich grain merchant Peter Verbeake.
Denne’s decision not to pursue Vincent through the courts may have been misguided. Shortly before their mother died in February 1634, Vincent allegedly persuaded her to leave most of her property to him, including the share of the Thanet estate reserved for Denne in their father’s will. In this way Vincent compensated himself for his impending loss of Denne Hill, which at long last passed to Denne. Vincent’s final act of spite was to settle most of his estate on Denne’s youngest son, Thomas, two months before his death in June 1642, leaving Denne only a single cottage and plot of land in Kingston, worth just £35.
During the First Civil War, Denne became recorder of Canterbury and chairman of the city’s ‘county’ committee. The assertion that he was a republican seems to be unfounded.
