Gewen is periodically referred to in contemporary documents as Guen, Gewine or Gowen.
Gewen probably entered Exeter College, Oxford in 1601, as he took his BA there three years later. In 1603, giving the college as his address, he contributed to a book of verses commemorating Elizabeth I. From Oxford he proceeded to the Inner Temple, following the plan laid down for him by his paternal grandfather in the 1602 will, which provided sufficient resources to educate him until he came of age. Clearly, the family’s hopes for the future rested squarely on Gewen who, in 1606, began to assume control of his inheritance even though his father was still living.
Gewen was therefore effectively an outsider when he was elected to Parliament at Bossiney in 1624. The borough came under pressure that year to accept duchy nominees, and Gewen’s election indenture described him as ‘auditor to Prince Charles’.
One of Gewen’s responsibilities as duchy auditor was the preparation of particulars for the award of leases, and in 1625 he apparently exploited his position to obtain for his mother a grant of Bradridge barton, one of the long-disputed properties. In the following year he had the lease transferred to himself, and then in 1628 renewed it on more favourable terms.
Gewen’s auditorship was renewed in both 1627 and 1630, while his elevated status in Cornwall was reflected in 1628 by his appointment as a j.p. However, the holding of office did not prevent him from emerging as a critic of arbitrary government, a stance which perhaps reflected the influence of his radical brother-in-law, Benjamin Valentine*. In 1629 he apparently obstructed militia reforms in Cornwall, and shortly afterwards he refused to compound for knighthood.
Gewen declined to contribute to the king’s northern expedition in 1639, and when the Civil War broke out he sided enthusiastically with Parliament, becoming one of its principal organizers in the West Country.
