Of obscure origins in Berkshire, More left Oxford without a degree to enter the service of Sir Ralph Winwood, a fellow of his college. When his master became a diplomat in 1604, More acted as his London agent, investment counsellor and newsmonger on a salary of £80 a year.
In August 1614 More acquired a quarter share in the lucrative salt monopoly headed by Charles Thynne* for £160, which he would not sell for £800; but, on behalf of one of his partners, he offered another quarter to John Packer*, Trumbull, and his own brother George.
Winwood died in 1617, leaving his affairs seriously embroiled, and his widow, suspecting malversation, brought More into Star Chamber. On 29 Apr. 1618 the letter-writer John Chamberlain informed (Sir) Dudley Carleton* that ‘our friend little John More is in a peck of troubles ... about a juggling deed of gift (as is pretended)’. Although Chamberlain feared an immediate adverse decision, litigation continued for another 12 years.
More’s third marriage to the great-niece of (Sir) Hampden Paulet† gave him a connection with the Hampshire gentry, and may, together with his interest in the salt monopoly, have assisted in his election as a freeman of Lymington in 1620.
More defeated Campion by three votes at the 1624 election, possibly with the support of his landlord, the earl of Southampton, who was anxious to strengthen the representation of the Virginia Company in the Commons.
More was re-elected at Lymington in 1626 without a contest. He is again difficult to distinguish from Poynings More in the records of this Parliament. In the debates on the embargo of the French merchant vessel St. Peter of Le Havre, it was doubtless he who argued on 23 Feb., and again on 1 Mar., that the French were at fault rather than the lord admiral, Buckingham, an early indication of his sympathy for the beleaguered royal favourite, and he proposed on 25 Feb. that impositions should be raised by parliamentary authority to finance coastal defence.
More’s outburst and the loss of his salt patent probably undermined his interest at Lymington, and he does not seem to have stood at the next election. After three decisions in Chancery, Lady Winwood lost her appeal to the Privy Council in 1632.
