Herrys came from a long-established Essex family. His father, an Essex sheep farmer, was knighted in July 1603, served as a captain in the militia c.1608-20, and sat on the county bench from 1614 until his death in 1632.
Herrys’ surname is variously recorded in the Commons Journal as Herrys, Herris and Harrys. He made his most conspicuous contribution at Westminster during a debate on the conduct of the war with Spain on 27 Feb. 1626. Taking his cue from Sir John Strangways, who deplored the neglect of the country’s coastal fortifications, and undoubtedly well briefed by his father-in-law, who had recently taken charge of the defence of Harwich, Herrys told the House that the forces assembled at Harwich ‘had neither bullets, guns nor powder’ and that the new fortress at Landguard Point lacked both gunners and munitions. He added, quite correctly, that the king’s ships were too sluggish to defend merchant shipping against an enemy whose vessels were ‘quick of sail’.
Herrys was not named to a single committee in 1625, and was appointed to only five in 1624. Of these, perhaps only the committee for examining a coal patent (24 May) directly concerned his constituents, whose ships were heavily involved in the coal trade. His membership of the committee for the bill to enable Sir Toby Palavicino to sell a 600-acre estate near Ilford, Essex (among others) undoubtedly reflected a more personal concern, as his father’s property at Shenfield lay seven or eight miles to the north-east of Ilford. The same may probably be said of his appointment to the joint conference with the Lords concerning the conduct of the former rector of Shenfield, Samuel Harsnett, as bishop of Norwich (15 May). His remaining two nominations dealt with the sale of Rampton manor, Cambridgeshire (6 Apr.) and the naturalization of David Stanniere (24 April).
In 1626 Herrys was named to eight committees. One dealt with the bill to punish Sir Robert Sharpeigh for reviving a duty upon Newcastle coals, a matter which undoubtedly concerned Herrys’s constituents (1 June). His appointment to the committee for drafting a bill to increase the wages paid to mariners employed by the Navy (22 Mar.) may also have interested the Harwich corporation. It was presumably because he was an Essex resident that Herrys was named to the committee for the bill to permit Edward Altham to sell land (18 March). His remaining committees were concerned with the Vincent Lowe land bill (1 Mar.); the fees levied by under-sheriffs and bailiffs for outlawries (1 Mar.); clerical magistrates (10 Mar.); the Giles Sewster land bill (13 Mar.); and subscription by ministers to the Canons of 1604 (6 May).
It is impossible to state precisely the number of committees to which Herrys was named in 1628 because he is not distinguished in the Commons Journal from the Member for Liskeard, John Harris II. He may have been the Mr. Harris named to the committee to consider the petition against the charges levied by London in metage and portage, as its members included Sir Harbottle Grimston (25 June).
Herrys may have been the author of a diary of public events, which is now located among the State Papers. It has been plausibly argued that it was written by an Essex lawyer, and it is clear from internal evidence that whoever wrote it was a Member of the Commons in 1628.
Herrys did not live to inherit his father’s estate. The main provision in his brief will, apart from the appointment of his widow as his executrix, was to order the payment of £360 to James Butler, who had sold him 46 acres of land near Shenfield in the previous year for £760.
