The Trenthams came from Shrewsbury, which borough Trentham’s great-grandfather Thomas represented in 1512 and 1515. Thomas’ son Richard, elected for Shropshire in 1536, relocated to north Staffordshire when he acquired the dissolved monastery of Rocester, close to the Derbyshire border. Trentham’s father was a client of the earl of Leicester (Sir Robert Dudley†) and represented Staffordshire in Parliament in 1571, while his eldest sister was a maid of honour to Queen Elizabeth and subsequently wife of Edward de Vere, 17th earl of Oxford.
Trentham was probably the 16-year old Francis Trentham of ‘Northumberland’ who matriculated from Trinity College, Oxford on 29 Jan. 1580. He was certainly the man who entered Gray’s Inn four years later, when he was described as being of Rocester. In 1586 he accompanied his father’s patron, Leicester, to the Netherlands as part of the earl’s train. He may have been abroad when his father died the following year, but had returned to England by 1592, when he married and was pricked as sheriff.
Trentham inherited a small amount of property in Shrewsbury in addition to his Staffordshire holdings, but by the time he died his estates were confined to Staffordshire, and were mostly in and around Rocester,
Trentham was elected to Parliament in November 1610 in place of Staffordshire’s junior knight of the shire, Sir Edward Littleton, who was too ill to serve any longer. However, he had little opportunity to play any part in the Commons’ proceedings, for not long after he was elected the session was prorogued (6 Dec.) and then dissolved (9 Feb. 1611). Unsurprisingly he left no trace on its records. In May 1615 Trentham was summoned before the Privy Council ‘concerning His Majesty’s service’, and in July he was removed from the bench.
Trentham’s father-in-law, Ralph Sheldon, was a notorious recusant, and, perhaps as a result, Trentham’s eldest son Thomas, knighted in 1617, inclined to Catholicism.
In November 1619 Trentham, correctly fearing he was losing his memory and reason, drew up his will. According to his bailiff, George Henshaw, he spent the final years of his life entirely under the control of his wife, during which time his estate was neglected.
