Originating in a new name for the abbey at Medeshamstede, and not the town, the name Burh was adopted for the abbey in the late 10th century, see Garmonsway (p. 117), also Mellows, William Thomas (ed.) The Chronicle of Hugh Candidus a Monk of Peterborough (pp.38 & 480) Oxford University Press, 1949, OCLC314897451; the addition of Peter, the name of the abbey's principal titular saint, parallels development of e.g. the name Bury St. Edmunds and will have served to distinguish between the two places. Exemplified in mediaeval records in the Latinised form Burgus Sancti Petri, this gave rise to the modern name Peterborough.
