Throckmorton’s forbears first settled in Warwickshire in the early fifteenth century. The Haseley branch of the family was established in the 1550s by his grandfather, Clement, who twice represented his county at Westminster. His father, Job, enjoyed the dubious distinction of having been imprisoned for his fiery outbursts over religion and foreign policy during the 1586 Parliament, though his principal claim to fame was his suspected authorship of the seditious Martin Marprelate tracts. Job endeavoured to inculcate the same puritan sympathies in his son, and in 1596 Throckmorton was sent to Emmanuel College, Cambridge, a recognized centre of radical Protestantism. More scholarly than most of his gentry contemporaries, he completed his bachelor’s degree, though for reasons which are unclear he transferred to Oxford for the final phase of his studies. Dugdale later noted him as being ‘not a little eminent for his learning and eloquence’, while Archdeacon Hinton of Coventry commended ‘his settled judgment in religion and his integrity of practice’.
Upon his father’s death in 1601, Throckmorton inherited an ostensibly moderate estate of some 600 acres and three-and-a-half manors, mostly located to the north and west of Warwick. As he was still a few months short of his 21st birthday, his mother purchased his wardship from the Crown.
Throckmorton finally entered the Commons in 1624 as a knight for Warwickshire, the third member of his family to represent a county during this period.
Re-elected by the Warwickshire freeholders in 1625, he was named on 21 June to the committee for privileges. On 23 June he condemned ‘the infinite confluence of priests and Jesuits into this kingdom’ as a prime cause of the spread of popery, and called for a petition to the new king requesting the expulsion of ‘these locusts’. He was appointed later that day to the committee stage of a bill against recusants, and on 27 June to the committee for the subscription bill.
In the 1626 elections Throckmorton was once more chosen knight of the shire. Appointed a second time to the committee for privileges, he was also included in a select committee to examine the conduct of the Leicestershire election (9 Feb. and 26 April). Now a relatively experienced Member, he was added on 25 May to the committee for drafting the subsidy bill preamble.
Throckmorton was critical of the conduct of the impeachment proceedings against Buckingham, and on 24 Apr. was one of the Members who voiced disquiet that evidence was being assembled in private by a select committee. During the debate on 4 May on the charge that the duke was responsible for the increase of popery, he referred the House back to debates several months earlier on the government’s attitude to recusancy, apparently implying that there was nothing new in the latest allegations. He was appointed to the select committee to determine how the Commons should request the Lords to confine Buckingham, and helped to gather the testimonies of sick Members in defence of Sir Dudley Digges, who had been arrested over comments made during the presentation of the impeachment charges (9 and 15-16 May). Nevertheless on 13 June he was scathing about the Remonstrance calling for the duke’s dismissal: ‘upon our conceits and conjectures, which are uncertain, we in this declaration desire a certain punishment: the removal of the duke from the king. This course I never heard of in any court and desire it may not be used by us who are judges’.
In the following months Throckmorton appears to have co-operated with the Forced Loan, but his role in local government was in decline. Although he remained a j.p. until his death, he was removed from the oyer and terminer commission sometime prior to 1629, probably because of financial difficulties. The cause of his problems is difficult to establish, but by 1632 he had sold off one-and-a-half of his manors, while between 1628 and 1629 his subsidy assessment was dramatically halved from his usual rating to just £10. When he died intestate in December 1632, administration of his estate was granted to one of his creditors. His grandson, Clement Throckmorton, regularly represented Warwick in Parliament from 1654 until his death in 1663.
