The Thynne family traced its roots to the Botfield family of Church Stretton, Shropshire, but were settled by the mid-sixteenth century in Wiltshire. Sir John Thynne (1513-80), the father of this Member, became steward to Edward Seymour, later Protector Somerset, under whose patronage he acquired a substantial estate, including the former priory at Longleat, which he rebuilt as an Italianate mansion. Four years before his death, Sir John married his son to the 17-year old Joan Hayward, the daughter of a wealthy London merchant, Sir Rowland Hayward. Though Joan was rather plain looking - even her father admitted that her ‘face was not so beautiful as some other’ - the marriage proved highly satisfactory.
Thynne was well connected at Court, as his brother-in-law was the courtier Sir Thomas Knyvett*.
Thynne had a reputation for irascibility. Indeed, even his friends criticized his ‘choleric outbursts’, and the Privy Council once condemned him for imprisoning a poor widow tenant and seizing her farm after failing to pay rent.
Improved relations with certain of the county gentry, and the support of his step-father Sir Carew Raleigh*, Sir James Ley*, and the lawyer Lawrence Hyde I*, may have helped Thynne, who had last sat for the county in 1589, secure the honour of representing Wiltshire a second time in 1604.
Many of the bill committees to which Thynne was appointed were concerned with the Church. They included measures on London tithes (10 May), the sale of episcopal lands (19May), pluralism (4 June), the import of popish books (6 June), scandalous ministers (12 June), the multiplicity of episcopal leases (13 June), the abuses of ecclesiastical courts (16 June), and non-attendance at church (27 June).
Following the end of the first session, on 11 Nov. 1604, Thynne was ordered by the Privy Council to release ‘an old gent whom he holdeth as a prisoner without cause’.
