Tyler was of obscure parentage. Born in West Hide, to the east of Hereford, his marriage brought him into a branch of the Scudamore family associated with moderate Presbyterianism.
Tyler was an active dean (later holding it in commendam with his bishopric), and he attended three out of every four audits held during his tenure of the office.
The death of William Beaw, bishop of Llandaff, on 10 Feb. 1706 provided an opportunity for Tyler’s elevation. Tyler was reluctant to accept ‘one of the poorest bishoprics in Christendom’ but Thomas Tenison, archbishop of Canterbury, ‘would not be denied’.
Tyler took his seat in the Lords on 3 Dec. 1706, the opening day of the parliamentary session. He attended on 80 days, 93 per cent of the total and was named to 37 committees. On 7 Jan. 1707 he was ordered to preach before the Lords on the 30th. On the 31st the House ordered publication of the sermon; it was in print and being circulated by 14 February.
Tyler was not present when the 1707-8 session began on 23 Oct., first sitting on 6 Nov. 1707 when the House got down to business. He attended on 87 days of the session, 81 per cent of the total. He attended the traditional dinner at Lambeth on 26 Dec. 1707.
Tyler was present on the opening day of the new Parliament on 16 Nov. 1708. He attended on 60 days of the session, 65 per cent of the total. Tyler joined the traditional dinner for bishops at Lambeth on 28 Dec. 1708.
Tyler did not attend the 1709-10 session and was thus listed as out of town at the time of the division on the Sacheverell verdict. In August 1710 he was again in Hereford.
As the political climate polarized even further within Convocation, Tyler was active in the Whig corner, especially in support of the beleaguered Tenison, under pressure from Francis Atterbury, the future bishop of Rochester, and his allies in the lower house, seeking to use the changed ministerial position to their advantage. Thus, on 23 Feb. 1711, Tyler attended a meeting at the home of Bishop Wake in Dean’s Yard to revise Convocation reports and negotiate with Philip Bisse, bishop of St Davids on the queen’s controversial new licence to the synod. Tyler was also involved in the committee of Convocation examining the Whiston heresy case.
With the Whigs mobilizing their resources for an attack on the ministry’s peace policy, Tyler’s name appears on a list compiled by Oxford, perhaps of possible supporters. If Oxford was hoping for Tyler’s support he was to be disappointed as Tyler entered his proxy in favour of Bishop Evans on 29 Nov. 1711 and was absent for the whole of the session which began on 7 December. He was in Hereford at the beginning of July 1712.
Tyler attended the St Stephen’s Day dinner at Lambeth at the end of 1712 and attended the prorogations of 13 Jan. and 17 Feb 1713. On 8 Mar. Tyler accompanied Wake to court for the queen’s birthday. He was not recorded as attending the prorogation on 10 Mar., but he dined that evening with Wake and the dean of Lincoln, Richard Willis†, the future Bishop of Salisbury.
In expectation of the parliamentary session, Tyler was in London by 3 Nov. 1713, being listed by Edmund Gibson†, the future bishop of London as one of the ‘bishops in town on our side’, along with John Moore, of Ely, John Hough, of Lichfield and Coventry, Richard Cumberland, of Peterborough, Charles Trimnell, of Norwich and Bishop Fleetwood.
At the accession of George I on 1 Aug. 1714 and the brief three week session that followed, Tyler attended on one day only (18 Aug.) to take the oaths. Clearly Tyler was now more in favour. On 25 Aug. Tyler visited Wake and on 1 Sept. when Wake visited Charles Montagu, Baron Halifax, he found Tyler there with Sir Peter King†, the future Baron King.
