"Magna Britannia" says of Derby School -

Whilst Richard Peche, who succeeded Walter Durdant in 1162, was Bishop of Lichfield, Walkelin de Derby and Goda his wife gave the mansion in which they dwelt, and which Walkelin had purchased of William Alsin, to the canons of Derley, on condition that the hall should be for ever used as a school-room, and the chambers for the dwelling of the master and clerks.
