Upton belonged to a cadet branch of an old Cornish family which acquired Lupton manor by marriage in about 1480.
Upton took no known part in Dartmouth’s affairs until 1625, when he was unexpectedly returned to Parliament for the borough. The beneficiary of a dispute between the merchant oligarchy and the lesser freemen, he was elected against the corporation’s wishes, the only outsider to win a seat there during this period. He left no trace on the proceedings of the first Caroline Parliament, but was evidently willing to serve without wages, and retained his Commons’ place for the rest of his life.
During the winter of 1625-6 the borough repeatedly sought Upton’s help with the intractable problem of billeting the troops returning from Cadiz. Despite this collaboration, on the day before the 1626 parliamentary election the corporation reaffirmed the traditional practice of returning only townsmen, and decried the choice of ‘foreigners ... such as are in no way acquainted with the town ... [and] its customs, nor experienced in its trades, nor what may tend to the benefit thereof’.
In 1627 the corporation again requested Upton’s assistance, this time in coercing certain townsmen into taking up municipal duties.
Upton’s puritan leanings became more pronounced during the following decade. In 1632 he bought a quarter of John Pym’s share in the Providence Island Company, for which he later acted as agent in the west of England.
Upton was elected for Dartmouth to both the Short and Long Parliaments, but died in September 1641. His fellow Members greeted the news of his demise with an outpouring of sorrow ‘for the loss of so worthy and useful a Member’.
