Although the younger son of the Caroline lord treasurer, Sir Richard Weston, this Member became his father’s heir-apparent sometime after 1622, when his elder half-brother ‘fell distracted’, as Chamberlain put it. On the ennoblement of Sir Richard in 1628, provision was made that the title of Lord Weston should descend to the children of Sir Richard’s second wife. This provision, which was repeated five years later when the lord treasurer became earl of Portland, ultimately proved unnecessary, however, as the elder brother, who had been confined at Coventry, died about a year before his father.
Weston was returned at Gatton in 1628 by William Copley, the Catholic lord of the manor, who claimed the sole franchise in the borough. However, two indentures were returned and the Commons declared Weston’s election void on 26 March.
Weston left no further mark on the records of the third Caroline Parliament until its end, when he was reportedly ‘much commended for a modest speech’ during the tumultuous events of 2 Mar. 1629 in defence of his father, who had become the target of (Sir) John Eliot and other disgruntled leading Members of the Commons.
In the autumn of 1629 Weston received a licence to travel for three years. He had returned by 1632, when he married Frances Stuart, cousin to the king, who gave her away, with ‘the queen looking on’, and Bishop Laud officiating.
Shortly after Weston succeeded as 2nd earl of Portland in 1635, George Garrard reported that his father had, before his death, ‘endeavoured with all his arts and power’ to get him a place at Court. This seems to have been true, for in December 1633 Edward Rossingham relayed rumours that Weston would shortly be appointed secretary of state, and in October 1634 it was said that Weston would soon be either secretary or master of the Court of Wards. However, the best that his father could do was to secure for him the captaincy of the Isle of Wight.
Weston won a temporary reprieve, but on the outbreak of hostilities in August 1642 he was detained and removed from office by the parliamentarians.
Weston drew up his will on 4 Nov. 1657, making his brother Benjamin Weston† executor, and added codicils on 27 Oct. 1660 and 8 Oct. 1661. He was buried on 22 Mar. 1663 at Walton-on-Thames. None of his descendants sat in the Commons. His only son was killed in the second Dutch War two years later, and the earldom of Portland passed to his Catholic brother Thomas, who died without issue in 1688, the last of the male line. His four daughters became nuns in Poor Clares’ convent at Rouen, which had been founded by his wife.
