The influence of the Somerset earls of Worcester in Monmouthshire was pervasive and authoritative. Their huge estates in south-east Wales, and their status as the only resident aristocratic family, gave them a considerable sway over county elections. The 4th earl was a crypto-Catholic, and Somerset was also interested in the old faith, befriending a seminarist, William Tayler, while at Magdalen in the 1590s.
Somerset’s father secured a place at Court after the fall of Robert Devereux, 2nd earl of Essex, and was probably responsible for obtaining his son’s post in the queen’s Household at about the same time. Through the earl of Worcester, a privy councillor, Somerset was dispatched to Scotland along with Charles Percy to notify James VI of the queen’s death and to present him with jewels.
Somerset was re-elected for Monmouthshire in 1604, doubtless with the encouragement of the king, who wished for loyal men in the House to advance his cherished design for Union with Scotland. Indeed, although not a dynamic Member, several of Somerset’s appearances in the parliamentary record certainly relate to Union. On 14 Apr. 1604 he was one of the 100 Members who attended the king’s initial speech about the Union, and he was among those delegated to discuss the Instrument of Union with the Lords (24 Nov. 1606).
Somerset was named to few committees, which is hardly surprising, as he had no legal training; he may also have found committee service uninteresting. His nomination to the committee for restoring the earls of Southampton, Essex and Arundel to their lands (2 Apr. 1604) probably reflects his family’s aristocratic interests and suggests that his father’s political agenda was just as important as his own. The same may be true regarding Somerset’s appointment to the committee to consider the Henrician Union statutes for Wales (21 Feb. 1606): as Worcester had recently acquired the lieutenancy of Monmouthshire and Glamorganshire, Somerset may have been briefed to ensure his powers were not circumscribed.
Somerset left for the continent in July or August 1610, shortly after the Parliament was prorogued, to join the English forces besieging Jülich in the Rhineland.
Somerset’s quest for a wife began in earnest at around this time, and though he was said to be ‘not worth above £500 a year’, in September 1613 it was reported that Anthony Browne, 2nd Viscount Montagu was considering him as a match for one of his daughters.
Somerset’s vigorous exploitation of the Barry lands and his hard bargaining over the wardship may have been occasioned by his awareness of Anne of Denmark’s declining health.
In 1621 Parliament scrutinized a patent for market tolls, in which Somerset held a share of the profits, but no action was taken against Somerset himself.
Somerset, who became Viscount Somerset in the Irish peerage in 1626, did not busy himself greatly with public life after 1623. In 1638 he petitioned for a grant of 4,000 acres of disafforested lands in the Forest of Dean ‘in consideration of his long and faithful service to Your Majesty, as also to your father and mother’.
