Thomas Vipont (1255-1256). This bishop enjoyed the bishopric for less than a year. He died in October 1256.
Two years elapsed before the next appointment.
Robert de Chause (1258-1278), Archdeacon of Bath; Chaplain to Queen Eleanor.
Again there was an interval of two years before the appointment of
Ralph Ireton (1280-1292), Prior of Gisburne. He was elected by the prior and canons of Carlisle, in 1278, without royal licence; so the king (Edward I.) fined the chapter 500 marks, and refused his assent. Eventually Pope Nicholas III. quashed the appointment on the grounds that it had been technically wrong, and then nominated Ireton to the vacant see. Edward agreed to this, pardoned the prior on payment of £100, and restored the temporalities in 1280. Ireton was avaricious, and extorted money from the clergy. This he used for building a new roof to the cathedral. He died in 1292, and was buried in the cathedral; where, shortly after, his tomb and a great deal of his work was destroyed by the great fire which occurred in May that same year.
John of Halton (1292-1324), Canon and Prior of Carlisle; Custos of Carlisle Castle. He defended the city against Wallace. The diocese suffered so often from the ravages of the Scots that more than once he had to obtain remission of the Papal taxation levied on the clergy. He was employed many times in various negotiations with Scotland, his last embassy being in 1320. He died four years later, and was buried in the cathedral.
John de Ros (or Rosse) (1325-1332), Canon of Hereford. He was appointed by the Pope to Carlisle in 1325. During his episcopate he was frequently non-resident. He died in 1332.
John de Kirkby (1332-1352), Prior of Carlisle, was bishop during very troubled times, and took part in many raids made on the Scots. He helped to raise the siege of Edinburgh in 1337. Five years later he took part in an expedition to raise the siege of Lochmaben Castle. In 1345 the Scots made a raid into Cumberland, and were defeated. The bishop, while fighting valorously against them, was unhorsed and nearly taken prisoner. The following year he was one of the English leaders at the battle of Neville's Cross. He died in 1352.
