Like his elder half-brother Thomas, Martin was trained up by his father as a cloth merchant. It is difficult to distinguish him in Exeter’s earliest Jacobean customs records from a cousin of the same name, but during the 1610s he apparently operated as Thomas’ junior partner, exporting Devon cloth to France, Spain and the Low Countries.
In 1626 Exeter corporation’s virtual monopoly over the choice of the city’s parliamentary representatives was challenged by the commonalty, who opted to elect their own nominee, Ignatius Jourdain. In 1628, in a bid to discourage such behaviour, the corporation offered the commonalty a choice of four candidates, including Martin. Unimpressed, the commonalty once again backed Jourdain, precipitating an election dispute. Two returns were sent up to Westminster, one for Jourdain and John Lynne, another corporation nominee, and the other for Martin and Lynne. The case was reported to the Commons on 26 Mar., and, given the clear evidence that Jourdain had attracted more votes than Martin, the latter’s election was overturned. Martin had travelled to London in the hope of obtaining a successful verdict, and the corporation’s displeasure at the outcome was signalled by its decision on 22 May to pay his expenses of £7 8s.
By 1628 Martin’s known trading activities were restricted to a handful of voyages to France and Ireland, and in the following year he was assessed for subsidy at the comparatively low figure of £7. However, his circumstances improved again thereafter, and by 1631 he was governor of the city’s company of merchants trading with France.
Martin made his will on 29 Aug. 1634, apparently still in good health. Childless, he bequeathed £600 and the bulk of his property to his younger brother John, while reserving a life interest in certain designated lands for his wife Susanna, to whom he also left £3,000. Assorted other relatives stood to inherit over £400 in total, and he donated £200 to an Exeter charity, St. John’s hospital. Martin died in the following October, and was buried, as he had requested, at St. Petrock’s, Exeter.
