A scion of what was technically the senior branch of the family of the dukes of Somerset, Conway had extensive connections and it is this that explains his elevation to the peerage as one of the four creations of 1703, rather than his own particular merits. Through the marriage of his cousin Alexander Popham to Lady Anne Montagu, Conway was related to Ralph Montagu* , duke of Montagu, and he was also a distant cousin of Robert Harley, earl of Oxford. His most influential relative by far was his father, the former Speaker of the Commons, and although their relations were at times far from amiable, Seymour was probably responsible for Conway’s return at Bramber in 1701.
While his promotion was largely due to his father’s manoeuvrings on his behalf, Conway was more than able to support his new quality, having inherited the estates (and acquired the surname) of the long-deceased earl of Conway when his brother Popham Seymour Conway was killed in a duel in 1699.
In the midst of these negotiations, Conway was elevated to the Lords as Baron Conway. Rumours of his expected elevation and that of a number of others had been current since the previous summer.
Although absent for the first two months of the session of November 1703, Conway was estimated by Charles Spencer, 3rd earl of Sunderland, in both of his forecasts to be a supporter of the Occasional Conformity bill. It was noted that his proxy was employed in support of the measure in a division of 14 Dec., though the proxy register has not survived. Conway resumed his seat on 12 Jan. 1704, after which he attended on just over a third of all sitting days. Despite being listed as present on the attendance list for 17 Feb., he was married to Lady Mary Hyde that same day.
Conway returned to the House at the opening of the following session in October. He was again named to eight committees in the course of the session but his rate of attendance declined and he was present for less than a quarter of all sitting days. Absent from the House from 18 Dec. he registered his proxy with his kinsman John Granville, Baron Granville, that day, which was vacated by his return to the House on 16 Jan. 1705.
Although absent from Warwickshire during the elections of the summer of 1705, Conway employed his interest on behalf of the sitting members and, following their successful re-election, he was assured by his agent that he had ‘carried in all the tenants according to your lordship’s commands’.
Although absent for much of December, he registered his proxy with his father-in-law, Rochester, on 8 Dec., which was vacated by his resumption of his seat the following month on 8 Jan. 1706. Three days later, the House took into consideration Conway’s petition to bring in a bill enabling the exemplification of the late earl of Conway’s will granted by the Irish courts to be used as evidence in trials at law there. Conway’s Irish relations, the Rawdons, had always disputed the earl’s will and he now found himself embroiled in a series of actions questioning the dispersal of the estates. His bill received its first reading on 15 Jan. and was committed the following day. The committee was chaired by Rochester and little over a fortnight later the House resolved to pass the measure and send it down to the Commons. On 22 Feb. Conway was nominated a manager of the conference considering Cary and Hatley’s bill. Six days later the House debated certain amendments proposed by the Commons to his own bill, after which it was resolved to hold a conference with the Commons to discuss their differences. Following the conference held on 2 Mar. agreement was reached and the bill received the royal assent later the same month.
Conway was missing at a call of the House on 29 Jan. 1707. On 1 Feb. he registered his proxy with his father-in-law once more, which was vacated by the close of the session. He then took his seat two months into the new Parliament on 17 Dec. but was thereafter present for just 9 per cent of sitting days in the session. He was listed as a Tory in an assessment of party classifications in May of the following year, the month that also witnessed the opening salvoes in a bitterly contested dispute when Buckingham exhibited a bill in chancery against Conway. At the heart of the case was the earl of Conway’s desire that after his death his half-finished mansion at Ragley should be completed.
Conway returned to the House on 18 Nov. 1708 but sat for just seven days before again quitting the chamber for the remainder of the session. His absence may have been owing to the loss of his wife in January 1709. If so, his period of mourning proved brief and at some point later that year he married again. He also had the embarrassment of having one of his former servants, Thomas Sheppard (‘about 5 foot 6 inches high, and great lips’), being sought after by local constables, having committed ‘notorious crimes’ that spring.
In common with a number of Warwickshire peers, he was presumably spurred into action by the prospect of the trial of Henry Sacheverell. A consistent supporter of the embattled doctor, on 14 Mar. 1710 he entered his dissent at the resolution not to adjourn the House and the same day subscribed the protest at the resolution not to include the particular words supposed to be criminal in articles of impeachment. Two days later he protested again at the resolution to put the question whether the Commons had made good the first article of impeachment against Sacheverell and subscribed a further protest at the resolution that the Commons had indeed made good the first article. On 17 Mar. he protested again at the resolution that the Commons had made good the second, third and fourth articles and the following day at the resolution to limit peers to a single guilty or not-guilty verdict. Predictably enough, Conway found Sacheverell not guilty of the charges against him on 20 Mar. and entered his dissent in response to the guilty verdict. The following day he registered his dissent at the censure passed against Sacheverell and acted as one of the tellers on the motion whether Sacheverell should be barred from receiving benefice for three years. The ending of the Sacheverell trial did not bring to a close Conway’s involvement in the session. On 30 Mar. he was named one of the managers of the conference concerning the amendments to the Eddystone lighthouse bill and on 1 Apr. he was one of the tellers in a division on the bill concerning the dispute between the inhabitants of Hammersmith and Henry Compton, bishop of London.
Conway returned to the House at the opening of the new Parliament on 25 Nov., after which he was present for almost 42 per cent of all sitting days. The following month it was reported by John Verney‡, Viscount Fermanagh [I], that Conway had commissioned a new carriage in preparation for his marriage to one of the maids of honour (a Miss Wyvell). Fermanagh must have been mistaken but the incident may indicate that Conway’s marriage to Jane Bowden was not yet widely known.
Further inaccurate rumours about Conway’s marriage circulated in November: this time a ‘Mrs Kingdom’ was believed to be the new Lady Conway.
Conway’s support for Oxford was said to be wavering at the beginning of 1712. On 2 Jan. he voted with Nottingham and a clutch of other Tory peers against adjourning.
Conway’s failure to compel Buckingham to finance the completion of Ragley may have been the catalyst for his decision to purchase Sandywell in Gloucestershire in 1712. Two years later he added the neighbouring manor of Whittington to his new estates.
Conway was granted an additional Irish barony in the autumn of 1712, perhaps as part of Oxford’s efforts to retain his loyalty to the ministry. News of the grant was published in the newspapers three months prior to the award being finalized, when it was also reported that he was to be added to the Irish privy council.
Conway was present for just seven days of the first session of the new Parliament. In May 1714 Nottingham forecast him to be in favour of the Schism bill. Following the death of Queen Anne, he attended just two days of the brief August session. He was present again on 21 Oct. but was afterwards absent from the House for almost three years. During his absence he suffered the death of his second wife, Jane, in childbirth and shortly afterwards the death of their two-month-old son, viciously reported by a Captain Moore to his Rawdon relations as ‘agreeable news’.
The reason for Conway’s complete retirement from the House is uncertain. A close friend and, by his third marriage, brother-in-law of Sir Robert Walpole* , later earl of Orford, Conway certainly does not appear to have been opposed to the new Hanoverian regime at all. It seems likely that after 1717 interest in his Irish estates may have predominated but during the 1720s he was also engaged in extending the house at Sandywell, so there is no reason to believe that he decamped from England altogether.
Conway died at Lisburn, co. Antrim, in February 1732. In his will, he left considerable bequests to his wife and seven surviving children, with the exception of Mary Conway, who was restricted to a legacy of £5 as a punishment for marrying without his permission.
