Thomas Breinton was from the leading family of Hereford, and, almost certainly, the son of another of the city’s MPs, George Breinton. This is implied by his first appearance in the records: on 15 July 1447 an attorney was named to give him seisin of property in Hereford put in feoffment by George’s father, William.
In a pattern typical of lawyers, Breinton’s single recorded election to Parliament came early in his career, perhaps when he was attending one of the Inns of Court. On 16 May 1450, during this Parliament’s last session, he joined another Herefordshire lawyer, William Wykes*, in offering surety for a third, Thomas Fitzharry*, MP for the county, in a royal grant; three days later, he and Fitzharry offered surety in a grant to Wykes.
Further evidence of Breinton’s Lancastrian sympathies is provided by attendance at the Hereford election to the Coventry Parliament of 1459; his appointment to the Lancastrian commission of array at the end of this assembly; and, more significantly, by the issue in August 1460, when the Yorkists were in control of government, of a commission for his arrest, along with those of Fitzharry and the mayor of Hereford, John Chippenham, to answer for spreading false news.
Breinton’s reappointment to the bench during the Readeption demonstrates that the Lancastrians had not forgotten his earlier allegiance; yet with Edward IV’s restoration his administrative appointments multiplied. He was named to several ad hoc commissions, including one of oyer and terminer within a few months of Edward IV resuming the throne; in 1472 he was on the pricked list for appointment as sheriff, a rare distinction for a citizen of Hereford; after a brief exclusion, he was routinely appointed to the county bench from 1473; and he was named as escheator in 1479.
Breinton’s prominence in local administration encouraged others to employ him. From early in his career he had acted as steward and clerk of the local courts of Hereford cathedral, and on 20 Sept. 1475 Thomas Myllyng, the new bishop of Hereford, nominated him as under steward of the episcopal lands in Herefordshire and Gloucestershire. Better records would no doubt reveal other similar appointments. With service came reward. On 28 Dec. 1482 the bishop gave him the wardship and marriage of his tenant, Robert, son and heir of Hugh Amondesham, and soon after Breinton married this ward to his daughter, Joan. The Amondeshams ranked among the county gentry, albeit the lesser ones, and the marriage served to confirm the social advance of a lawyer who had turned himself from a citizen of Hereford to a royal officer in the county.
Breinton’s administrative role survived the usurpation of Richard III and the accession of Henry VII. He maintained his place on the bench through this troubled period, and the family made a further social advance in the early part of Henry VII’s reign. In November 1485 he was named for his second term as escheator of Herefordshire, and, more significantly, his son John, a lawyer of Lincoln’s Inn, was appointed as feodary of the manor of Fownhope. Soon afterwards the latter contracted a marriage that firmly established the Breintons among the county gentry. On 4 Jan. 1487 John was dispensed to marry Sibyl, widow of Richard Hakeluyt of Eaton Gamage and one of the daughters of the influential Simon Milborne of Tillington.
During the course of this long career, Breinton acquired a landed estate in Herefordshire, but the process of acquisition can only be dimly grasped in the surviving records. From his mother he appears to have inherited property in Yarpole and Orleton in the north of the county, and by early in his own career he also had land at Wellington, a few miles to the north of Hereford, for he was described as a gentleman of that place when offering surety in 1450.
