Pollexfen was born around 1638, the second son of Andrew and Joan Pollexfen of Sherford, Devon. He died in London early in 1715, and was buried on 15 February in St Stephen, Walbrook. Pollexfen was obviously educated, though he does not seem to have been to university. He moved at some point to London, where he married Mary Lawrence on 10 May 1670 and became a highly successful merchant. He is mentioned in 1675 as attending the Committee for Trade and Plantations, and in 1680 as ‘an agent appointed by the Western towns to attend the Lords in the business of Newfoundland’ (Calendar of State Tapers (Colonial) 1677–80: 612)). He was MP for Plympton Erie, Devon, in 1679, 1681, 1689–90 and 1690–95. Despite standing down from parliament on grounds of ill health, he then sat on the Board of Trade (also known as the Commissioners for Trade and Plantations) from its creation in 1696 until 1707, drawing an annual salary of £1,000.
