Plumleigh belonged to a merchant family which rose to prominence in Dartmouth in the second half of the sixteenth century. Like many of his kinsmen, he profited from the town’s lucrative trade with Newfoundland, France and Spain.
In 1624 Plumleigh was elected to represent Dartmouth in the Commons. His return was apparently unopposed, though he may have been viewed as a temporary replacement for the borough’s regular choice, Roger Mathew, who was currently the mayor, and therefore ineligible to stand. In marked contrast to his colleague Nyell, Plumleigh is not known to have contributed to the Commons’ debates, nor did he attract any personal nominations. However, he did attend the committees for the bills to enfranchise county Durham, and to reform corrupt customs officials. The latter issue was of particular concern in Dartmouth, and he and Nyell were both regular faces at the relevant committee. Plumleigh probably helped to procure for the town its lengthy copy of the trade grievances presented by the Commons to the king, many of which reflected Dartmouth’s complaints. He was paid £30, at 5s. a day ‘for his expenses at the Parliament’.
In 1625 Plumleigh was replaced in the Commons by a country gentleman, John Upton. Later that year he was again chosen as mayor, in which capacity he presided over the 1626 parliamentary election. On the day before the vote, the corporation passed a new by-law which aimed to reinforce the custom of electing only townsmen. However, this move failed to prevent the freemen from again choosing Upton.
Plumleigh’s cousin Richard was attacked during the 1628 Parliament as a Catholic convert, but he himself contributed generously to the rebuilding of St. Saviour’s church in 1631.
