Gawen was descended from a Catholic family which had been settled at Norrington, Wiltshire, since at least the early sixteenth century. One of his cousins became a nun in France, while another was repeatedly cited for recusancy.
Gawen was returned for Heytesbury, less than five miles from Imber, in 1604, presumably with the backing of the borough’s main patron, Sir John Thynne* of Longleat. Before 1602 Gawen had been granted an annuity of £30 charged on the estate of Sir Walter Ralegh†, the brother of Thynne’s step-father, (Sir) Carew Ralegh*, but no more substantial link between the two men has been established.
Gawen spoke again at the second reading of a bill to relieve imprisoned debtors on 27 Mar. 1606. He warned that if the bill passed many would ‘lie in prison and live one year on the alms basket: and afterwards when they are confined to reside within five miles they will remain in London, and their work shall be to stir up suits and to solicit against them at whose suits they were imprisoned’. His objection was clearly based on painful experience, for he went on, ‘myself have been so used therefore I pray you either pass not the bill or confine the parties five miles from London’.
Re-elected to sit again for Heytesbury in 1614, Gawen is not recorded as having made any contribution to the work of the House during the brief Addled Parliament. Little has been ascertained of his later years. In 1626 he settled his property on his daughter at her marriage; he was dead by 1633 when an inquisition of his estate was taken.
