In 1410, John de Macclesfield, clerk was granted, by Henry of Monmouth (later Henry V), a Chester licence to crenellate Macclesfeld (Buckingham Castle, Macclesfield)

"licence to kernellate his mansion in the town of Macclesfeld"

A repeat of the 1398 licence. This licence is sometime confused with a licence of 1410 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.)

Significant later source are;
