Long established in Essex, the Herrys family had achieved gentry status by the dissolution of the monasteries.
Although unacquainted with most of the members of Maldon’s corporation, Herrys wrote to the town’s bailiffs in November 1619 to recommend the clerk of the Commons, John Wright, following the death of their recorder (Sir) Charles Chiborne*.
During the course of his first Parliament, Herrys never addressed the House and played only a minor role in its affairs. On 3 Apr. he was named to attend a joint conference with the Lords concerning recusancy. He was subsequently appointed to six legislative committees, two of which dealt with bills permitting particular landowners to disentail part of their estates (24 Apr. and 19 May). Herrys is not known to have been connected with either of the intended beneficiaries of the legislation, Sir Richard Burneby and Sir Toby Palavicino, but among the properties that Palavicino wished to sell was a 600-acre estate near Ilford, Essex.
Herrys proved the popular choice for Maldon’s first seat in April 1625, but sat as junior knight of the shire for Essex, having received the support of the earl of Warwick, who endorsed him as one ‘whose understanding and integrity well deserves that employment’.
Herrys was relegated to Maldon’s junior seat in 1628, doubtless because his constituents were eager to favour Sir Henry Mildmay of Wanstead, whom they hoped would use his Court connections to rid the town of a company of Irish soldiers which had been billeted upon them. Despite his lack of parliamentary stature, Herrys was named to the committee for privileges (20 March). Maintaining his customary low profile in the House - he is never recorded as having spoken - he was appointed to just two legislative committees, on 6 May 1628 and 12 Feb. 1629, concerning bills to enable Vincent Lowe of Denby, Derbyshire and Edmund Hamond of Essex to sell entailed land.
Following the ending of the third Caroline Parliament, advancing age induced Herrys to retire from active service on the county bench, although he was one of two Essex magistrates who apprehended the ringleaders of a riot at Burrow Hill, near Maldon, for which he was congratulated by the Privy Council.
