At the age of 11 Hungerford inherited the estates of his great uncle, Sir Edward, having spent part of his childhood as a member of the latter’s household at Farleigh Hungerford.
Hungerford was returned on the strength of his family’s local standing for Wootton Bassett in 1614, while still under-age. He left no trace on the records of the Addled Parliament. In 1620, by which time he was resident in the parish of St. Martin-in-the-Fields, he married the daughter of William Halliday, a wealthy London alderman. Her dowry comprised £14,000, together with the manor of Corsham and properties in Chippenham, Stanton St. Quentin, and Monkton Farleigh.
By 1624 Hungerford was both a magistrate and deputy lieutenant for Wiltshire, and was returned for the county at the general election for James’s last Parliament. Although not appointed to the privileges committee, Hungerford closely followed the Chippenham election controversy, in which John Pym* had secured the votes of seven burgesses for the junior seat, and Sir Francis Popham* had won the support of the bailiff, five burgesses and up to 30 townsmen, resulting in a double return. The case sparked a franchise dispute; but Hungerford, seconded by Sir Robert Phelips, successfully moved on 25 Feb. 1624 that Popham should be admitted to the House.
Hungerford’s ownership of a house in Bath presumably facilitated his election for the borough in 1625. He was appointed to one committee, to examine Exchequer debts (25 June), but left no other trace on the records.
In 1634 Hungerford became embroiled in a protracted lawsuit involving the marriage of his mother-in-law Susan Halliday to the 2nd earl of Warwick (Sir Robert Rich*). Hungerford, along with (Sir) Henry Yelverton* and Susan’s brother Sir Henry Roe, had been executor to William Halliday’s estate, and he was also a signatory to an indenture allowing Warwick a marriage portion of £7,000 for her maintenance in the event of his death. Hungerford and Yelverton had each been entrusted with £1,500 of this portion, and sued Warwick after discovering that he had given the money to his son and daughter without consulting the trustees.
Throughout the Civil War, Hungerford used Corsham as a base for his activities as the commander of parliamentary forces in Wiltshire.
