Martin of Ramsey (1226-1233), one of the monks, was chosen to succeed Alexander. He remained only six years. After his death another monk, Walter of S. Edmunds (1233-1245), was elected. He was a great builder. It was during his time that the minster was solemnly re-dedicated. This abbot made no less than three visits to Rome. On the third occasion he was summoned in consequence of some irregularity in an appointment to the living of Castor; but he seems to have managed his case very adroitly, and to have escaped all censure by assigning an annuity of £10 a year to the Pope's nephew. Another account, however, represents the abbot as being so distressed at the indignities he suffered at the Papal Court, that, being unwell before he went there and his infirmities being increased by his journey, he died very soon after his return to England. "He left the abbey abounding in all good things; stored with horses, oxen, sheep and all cattle in great multitudes, and corn in some places for three years." He died in 1245.

William de Hotot (1246-1249), another monk of the house, succeeded Walter. He held the office only three years, when he resigned and was assigned a residence at the manor of Cottingham, afterwards exchanged for one at Oxney, a few miles only from Peterborough. It is said that his resignation was caused by complaints being made of his enriching his own kinsfolk, "whereof he had great multitudes swarming about him," at the expense of the monastery. But the injury he did could not have been very considerable, for his body was brought to Peterborough to be buried, and he had an honourable commemoration in the Church's calendar.

John de Caleto (1249-1262), that is, of Calais, came here from Winchester, where he was prior. He was related to the queen. As one of the Chief Justices he went on circuit. But he seems to have taken the side of the Barons in the civil war, and is said to have held the office of treasurer to them for the last two years of his life. He was seldom in residence at Peterborough, but appointed a very efficient deputy, who afterwards succeeded him as abbot.

Robert of Button (1262-1274) fought in the battle of Northampton against the king. The king, coming to assault the town, "espied amongst his enemies' ensigns on the wall the ensign of the Abbey of Peterburgh, whereat he was so angry that he vowed to destroy the nest of such ill birds. But the town of Northampton being reduced, Abbot Robert, by mediation of friends to the king, saved both himself and church, but was forced to pay for his delinquency, to the king 300 marks, to the queen £20, to Prince Edward £60, to the Lord Souch £6, 13s. 4d." When the fortune of war changed and the Barons were victorious at Lewes, "then did the other side fleece the Abbot of Peterburgh for his contribution to the king." After Evesham again the king repeated his exactions, and the unfortunate abbot had to pay enormously. The total amount that he paid on these several occasions is put down at a sum which seems almost impossible, being upwards of £4320. This abbot attended the Council of Lyons in 1273, and died abroad as he was returning to England. He was buried abroad; his heart, being brought to Peterborough, was interred before the altar in one of the chapels in the south transept.

Richard of London (1274-1295) is said to have been born in the parish of S. Pancras. He was a monk of the house, and while sacrist had erected the Bell-tower and given two bells. A great deal of litigation was carried on in his time, and he and the abbey were fortunate in having in one of the monks, William of Woodford, a man of great skill and judgement, to conduct the different cases before the courts. So uniformly successful was he and so wisely did he act as coadjutor of Richard when he became very old and infirm, that he was elected to the abbacy on the death of Richard of London in 1295.

William of Woodford (1295-1299) only lived four years after he became abbot. After him came Godfrey of Crowland (1299-1321), the celerarius of the monastery. He is very highly praised in the chronicles for the various services he rendered to the abbey. More than once he was at the heavy charge of entertaining the king and his court, and he contributed largely to the expenses of the war with Scotland.

Adam of Boothby (1321-1338), one of the monks, was a man of great "innocence and simplicity" His revenues were much employed in contributions to the king's expenses and in royal entertainments; and his energies devoted to divers legal difficulties connected with manors, wardships, repairs of bridges, rights of hunting, and the like. Of the last eleven abbots, whose rule extended over a period of 124 years, all but one had been monks of the place.

Henry of Morcot (1338-1353) in all probability was also one of the monks, but this is not so recorded. And the same may be said of all the remaining abbots, but the historians do not say so until the time of William in 1471. At the same time it is never said that any of them came from elsewhere.
