A younger son from a long established Devonshire family, Reynell became a courtier and a soldier. A gentleman pensioner by 1593, he was prevented from serving on the 1597 Azores expedition by a sudden illness, but nevertheless subsequently commanded a company in Ireland, where he distinguished himself by his courage and was knighted by the lord lieutenant, Robert Devereux, 2nd earl of Essex, in July 1599. Though associated with Essex, he took care to cultivate Sir Robert Cecil†, to whom he may he may have owed his return for Callington in 1593. Consequently, although he was imprisoned after Essex’s rising in 1601, he was promptly released and suffered no apparent impairment to his career. It was almost certainly Cecil who was responsible for his election for Lancaster to the Parliament held later that year. Two years later Reynell attended Elizabeth’s funeral in his capacity as a gentleman pensioner.
In 1603 Reynell was granted the reversion to the lieutenancy of Portland, Dorset, but he was never to hold the office.
In 1614 Lord Knollys (William Knollys†), treasurer of the Household and Reynell’s neighbour in Charing Cross, nominated him as a Member for Wallingford, where Knollys was high steward.
On 7 May Reynell spoke on the Sabbath bill, probably in favour of it as he had approved a similar measure in 1601, and was thereby entitled to attend the committee.
On 17 May Reynell was highly critical of Richard Martin* for his speech, as counsel, on the Virginia Company: ‘the more his knowledge and experience, the more his error worthy of punishment’. When John Osborne†, remembrancer of the Exchequer, asked to be heard on the bill for regulating the fees of certain Exchequer officers three days later, Reynell pointed out that Osborne had ‘produced an ancient patent, confirmed by an Act of Parliament, last Parliament’. In the debate on subsidy on the last day of this Parliament he spoke ‘against giving now’.
In 1615 Reynell and his brothers were the dedicatees of the published version of the sermon preached at the funeral of their sibling Josiah by John Preston, not the famous puritan minister of that name, in which they were described as ‘lovers of true religion, and favourers of all true professors’.
Reynell was returned for Cricklade to the third Jacobean Parliament probably at the nomination of Knollys’ father-in-law, Thomas Howard, 1st earl of Suffolk. In addition, Reynell was related by marriage to Sir John Hungerford*, who had represented the borough in 1604. He was appointed to seven committees and made two speeches. On 22 Feb. he was added to the sub-committee of the committee for courts of justice to receive petitions, and named to consider bills on recusants’ lands (2 Mar.), free trade in Welsh cloth and cottons (16 Mar.), the waste of gold and silver in clothing (21 Apr.), and the abatement of usury (7 May), as well as to two private bills (16 Mar. and 17 May). On 7 May he proposed that the House should command two quarrelsome Members, Sir Charles Morrison and Clement Coke, ‘not to meddle’ while their case was under consideration. A week later he was one of the three Members who spoke in grand committee in favour of the glass patent held by Sir Robert Mansell*, apparently on the ground that the king had power to prohibit imports and that drinking glasses had not been made in England before.
In his will of 12 Jan. 1624, Reynell provided £100 for his burial. He bequeathed his Charing Cross lease to his ‘loving wife’ and residuary legatee. While leaving rings to various close relatives, he gave the 3rd earl of Essex ‘one tablet jewel’ set with diamonds, his father’s picture, and £30 ‘to be bestowed upon the making of the said jewel fit to receive the said picture’. He explained that this was in remembrance of the favours he had received from the 2nd earl, but gave no explanation of a bequest of £30 to a schoolboy, William Hyde, which was not to be put into his parents’ hands without good assurances. Although he made no reference to his physical health it is possible that he had been prompted to draw up his will by illness, which would explain why he was not elected to the 1624 Parliament. He died on 7 Sept. 1624, in his 61st year according to his funeral monument, and was buried a week later at St. Martin-in-the-Fields.
