Descended from a family settled at Milborne St. Andrew, Dorset, Morton was the youngest son of an impoverished soldier who lived near Canterbury and twice represented Hythe in Parliament. Despite his father’s limited means, Morton was educated at Eton and perhaps also at Westminster. He was subsequently refused admittance to Trinity College, Cambridge, despite a testimonial from the king, but obtained a scholarship at King’s.
Morton was awarded his BA in 1607, and by June 1609 he was back in Venice, when he was again dispatched to England, this time with testimonials addressed to the king, Prince Henry and Robert Cecil†, earl of Salisbury.
On returning to England, Morton was almost killed at Charing Cross when, on 21 May 1613, the coach’s horses suddenly bolted. Attempting to leap clear, he became entangled with ‘one of the pins of the boot, from whence struggling to get loose, he broke the waist-band of his hose behind, and so fell with the greater violence on the ground’. He briefly lost the power of speech, and the left side of his body suffered partial paralysis.
Morton was not recalled to diplomatic duty until March 1616, when he was appointed secretary to James’s daughter Elizabeth, the Electress Palatine, though he did not leave until October.
Morton remained in England until at least mid-June, ostensibly to receive the proceeds of a Benevolence intended to pay the cost of raising 4,000 troops for the Bohemian cause.
Morton resigned his clerkship in January 1623 in protest at being excluded from sensitive negotiations over the Spanish Match. He nevertheless continued to expect employment, and indeed hoped to succeed Wotton at Venice, a country he greatly admired.
Before Morton left England a Parliament was summoned. Not being a peer, Morton was obliged, as a secretary of state, to seek election. He looked both to his alma mater, Cambridge University, which was rapidly becoming established as a safe constituency for holders of his office, and his former home county, Kent. In the run-up to the Kent election he enjoyed the support of Buckingham, who as lord admiral ordered the navy’s servants at Chatham and Rochester to be mobilized on his behalf, and the county’s lord lieutenant, the earl of Montgomery (Sir Philip Herbert*).
While en route to France Morton was appointed extraordinary ambassador to the United Provinces, and on the conclusion of his business in Paris he travelled to The Hague, where he was instructed to clarify the arrangements for the forthcoming Anglo-Dutch naval expedition against Spain and begin negotiations for a concrete military alliance. However, though fluent in Italian Morton knew little Dutch, and made such a poor impression that he was soon recalled, ostensibly to allow the negotiations to continue in London.
