Gilbert Welton (1353-1362). The chapter of Carlisle had, with the king's leave, elected John de Horncastle, but the Pope annulled the election, and made Gilbert Welton bishop. He was a very busy official of the king; amongst other matters he was one of the commissioners who treated for the ransom of David of Scotland, and was also a warden of the western marches.
Thomas Appleby (1363-1395), Canon of Carlisle. More than once during his episcopate he was a warden of the western marches. In 1372 he was required by the king, in conjunction with the Bishop of Durham, and others, to be ready to repel any invasion by the Scots. He was also one of the commissioners, in 1384, to treat with the king of Scotland for a renewal of the truce, and, in 1392, to execute that part of a treaty with France which concerned Scottish affairs. He died in 1395.
Robert Reade (1396-1397), a Dominican friar. In 1394 he was appointed by the Pope to the bishopric of Waterford and Lismore, and, in spite of the election of William Strickland by the canons, translated to Carlisle, whose temporalities he received in March 1396. In October, however, he was translated (by Papal bull) to Chichester, receiving the temporalities of that see May 1397.
Thomas Merke (or Merkes) (1397-1400). Educated at Oxford. The Pope, at the king's request, compelled the chapter of Carlisle to elect him in 1397. He is said to have been a boon companion of Richard II., and remained faithful to that king. He was one of the eight whose safety Richard demanded when surrendering to Bolingbroke. He is said to have made a strong protest in Henry IV.'s first parliament (October 1399) against the treatment which Richard had received. The following January he was tried for high treason, and, after being deprived of his bishopric, was committed to the Abbey of Westminster (23d June 1400). Pope Boniface IX. intervened in his favour, and, by translating him to a titular eastern see (ad ecclesiam Samastone), prevented his being degraded and handed over to the secular arm. He died in 1409, having, after his deposition, held benefices at Sturminster, Marshall, and Todenham, his eastern see affording him no revenue.
William Strickland (1400-1419), whose election (after the death of Bishop Appleby) had been annulled, was now made bishop. He rebuilt the tower of the cathedral, and provided the tabernacle work in the choir. He also furnished Penrith with water from the Petteril. He died in 1419, and was buried in the cathedral.
Roger Whelpdale (1420-1422). Educated at, and Fellow of, Balliol College, Oxford; Provost of Queen's College. He founded and endowed a chantry in the cathedral, and made various bequests to his old colleges at Oxford, dying in London 1422.
William Barrow (1423-1429), Chancellor of the University of Oxford; translated from Bangor. In 1429 he was one of the commissioners for the truce with Scotland which was concluded at Hawden Stank. He died in 1429, and was buried in the cathedral.
Marmaduke Lumley (1430-1450). Educated at Cambridge; Chancellor of the University of Cambridge and Master of Trinity Hall. In 1447 he became Lord High Treasurer of England. Queen's College, Cambridge, was indebted to him for gifts of money towards its building, and books for its library. He was translated to Lincoln in 1450, and died in December of that same year.
Nicholas Close (1450-1452), Fellow of King's College, Cambridge; Chancellor of the University; Archdeacon of Colchester. Translated to the bishopric of Coventry and Lichfield 1452, and died two months after his translation. He was a great benefactor to King's College.
William Percy (1452-1462), Chancellor of the University of Cambridge. Died in 1462.
