Evelyn’s great-grandfather moved from Middlesex to Surrey in the early sixteenth century. The family’s fortune was made in the next generation when Evelyn’s grandfather George acquired the monopoly for making gunpowder.
Evelyn’s elder brother George made a fortune as a Chancery official, which he passed on to Sir John Evelyn*; but Evelyn himself entered the family business. It is difficult to distinguish him from his father until the latter’s death in 1627. Nevertheless, it seems to have been Evelyn himself who petitioned the Privy Council in 1617, as he referred to a patent granted by Elizabeth to his father and grandfather for making gunpowder. In this petition he complained that his family’s works had been rendered useless by the transfer of the monopoly to the 4th earl of Worcester in 1607 after complaints in the first Jacobean Parliament. Worcester surrendered his patent to a commission headed by Buckingham, who concluded a new contract with Evelyn and his father in 1621 to make gunpowder.
The contract was renewed at intervals against a background of continual difficulty and dispute, with the manufacturer unable to obtain either raw materials or regular payment from the Crown. In 1624 either Evelyn or his father was ordered to bring his patent before the Commons after the House passed a motion blaming him for the scarcity of gunpowder. He did not have one, however, and there were apparently no further proceedings in the matter.
The Evelyns were reluctant to pay prerogative levies in the 1620s. Either Evelyn or his father was called before the Privy Council in 1622 to account for his failure to contribute to the Benevolence.
In January 1628 the earl of Totness (Sir George Carew I*), the master of the Ordnance, wrote to Buckingham that there was little expectation of receiving more gunpowder from Evelyn because of the substantial arrears owed to him.
In February 1628 Evelyn secured his election for Bletchingley, two miles from Godstone. He was probably motivated by a desire to liberalise the trade in saltpetre, an important raw material in the production of gunpowder which was controlled by a commission consisting of Buckingham and Totness. On 13 Mar. the minutes of the Council of War referred to a bill preferred in Parliament by Evelyn concerning saltpetre.
Parliament presented dangers as well as opportunities for Evelyn. Speaking on 23 Apr. Edward Alford complained of the scarcity of gunpowder, and claimed that it was ‘all gotten upon into one man’s hands’ - presumably a reference to the monopoly which Evelyn enjoyed under licence from Buckingham.
On 4 June Evelyn again raised the issue of saltpetre in the Commons, calling for the power of the committee appointed on 25 Apr. to be augmented to enable it to call witnesses and carry out examinations. He outlined his family’s history in the production of gunpowder. Possibly hoping to distract attention from himself, he complained of Bludder’s selling of it ‘out of the Tower’, a practice which, he alleged, increased the price. Other Members complaining about the export of ordnance followed him, and both questions were referred to a new committee, to which Evelyn was appointed.
On 19 June the Privy Council agreed that Evelyn should be paid his arrears ‘out of the first monies that shall come in or be raised upon the first subsidies now given in Parliament’.
After finally losing his contract in 1636, Evelyn complained that the erection of mills had impaired his estate by at least £5,000, and it was several years before he was cleared of all responsibility for the failure to maintain the supply of powder.
