In 1398 Aug 30, John de Macclesfield, clerk was granted, by Richard II (as Earl of Cheshire), (In year 22 of his reign) a Chester licence to crenellate mansion en v're ville de Macclesfeld (Buckingham Castle, Macclesfield)

"John de Macclesfield, clerk, petition of, to the King, for licence "de batailler et kerneller de pere et de caux ses chambres de novel comencees en sa place ou mansion en v're ville de Macclesfeld," and to hold the same so kernellated to himself and his heirs for ever; also for a grant of six oaks from the wood of Lyme for the same building."

The petition, dated July 1 was granted Aug 30. This licence is sometime confused with a licence of 1399 granted to the abbot of Chester (Who was Henry de Sutton)

(In fact, the original source given is usually a transcription/translation of what are precious medieval documents not readily availably. It should be noted that these transcription/translations often date to the nineteenth or early twentieth centuries and that unwitting bias of transcribers may affect the translation. Care should also be taken to avoid giving modern meaning to the medieval use of certain stock words and terms.)
