According to the Somerset antiquarian Thomas Gerard, who was a friend of Kirton’s nephew Edward*, the Kirtons originated in Essex.
Two of Kirton’s brothers followed their father into Hertford’s service, as did other members of the family. Kirton, the fourth of six sons, may have been intended for the same course from a young age, but during the second half of the 1580s, when he was at the Middle Temple and travelled abroad, he evidently contemplated alternative employment. Nevertheless, he entered the earl’s service in around 1592, and from 1599 was being employed ‘on matters of the greatest trust’. It was probably at this time that he became the earl’s steward, the position he held during Hertford’s embassy to Brussels in 1605.
Kirton undoubtedly enjoyed Hertford’s support in the parliamentary election for Ludgershall in 1601, and his continuing service with the earl explains his re-election to the borough in 1604 and 1614. The Commons Journal does not differentiate between Kirton and his cousin, James Kirton II, who also sat in James’s first Parliament. The latter, a barrister, was also connected with Hertford, but not as closely as this Member. It was therefore presumably Kirton who was named on 21 Apr. to consider the bill for assuring property to the dean and chapter of Windsor, which also confirmed a lease of tithes belonging to the dean and chapter to Hertford. The bill was passed and the lease was subsequently conveyed to Kirton as Hertford’s trustee.
Kirton’s principal concern in the 1604 session was the bill promoted by his patron’s nephew, Edward Seymour*, to secure possession of property in Devon that had formerly belonged to the duke of Somerset, but which Hertford desired for himself. It was probably this Member, rather than his namesake, who successfully moved on 27 Apr. for counsel to be heard concerning the measure. It was certainly this Member, described in the Journal as ‘servant and officer to the earl of Hertford’, who secured an order of the House for Seymour to leave the chamber for the second reading debate on 12 June. In response, Seymour’s allies moved that Hertford’s officers should also depart but this was rejected as they were ‘no parties themselves’. Kirton was therefore among those named to consider the matter, which was never reported.
Other references in the parliamentary records are harder to attribute to Kirton rather than his namesake. One or the other was named to the delegation to present an address on the abuses of purveyors on 27 Apr., and on 7 May he was one of the Members listed as being able to provide proof of the House’s articles on that subject. A week later a ‘Mr. Kirton’ spoke in the debate concerning the case of Sir Thomas Shirley I*, who had been arrested for debt shortly before the session. He suggested that Parliament should legislate to disable the warden of the Fleet, who had refused to release Shirley, from holding office. In addition, one or other spoke on the Form of Apology and Satisfaction of the Commons at its second reading on 20 June, though to what effect is not known.
Kirton received one committee appointment in the 1605-6 parliamentary session: both this Member and his namesake were added to the committee to consider the Marshalsea bill on 21 March.
After 1608 Kirton was ‘employed on less weighty matters but still enjoyed his [Hertford’s] favour’, which suggests he ceased to be the earl’s steward at that date, but remained in his service.
In his service as Hertford’s steward, Kirton had been frequently bound for his employer’s debts and had made extensive purchases on the earl’s behalf. According to his later account, Kirton became worried that he would not be paid what the earl owed him, and in 1611 he persuaded Hertford to convey certain lands to him. These may have included an estate in Sopworth, Wiltshire, and a house in Smithfield, London, both mentioned in Kirton’s will as having formerly been Hertford’s property.
Kirton was re-elected in 1614, presumably with Hertford’s support, when his only recorded contribution to the work of the House was to suggest that the issue of undertakers should not be put to the question (2 May), arguing that ‘one accusation will beget another’.
The following year saw a significant breach between Hertford and Kirton, when the former tried to challenge the 1611 conveyance of property.
In his will of 20 July 1620, Kirton asked to be buried without ‘vain and unnecessary pomp’. He left his interest in Almsford Park to his mother, and then after her death to his nephew Edward Kirton*, who also received property in the neighbouring parish of Castle Cary. He set aside £210 to clear a debt of his recently deceased brother-in-law (Sir) Edward Morley*, while his own debts were to be satisfied by the sale of land he had been granted in Sopworth and Smithfield. Another Wiltshire property was to be sold to a great-nephew for £500. He further ordered the distribution of £680 in gifts and annuities to various relatives, but made a plaintive reference to £750 in pension arrears due from the Crown. Edward was appointed executor and heir to the remainder of the estate, provided he gave security to John Wightwick*, Sir Henry Berkeley* and William Chaffin that he would faithfully execute the will.
