There is insufficient evidence to be certain about this possible licence to crenellate. (Some licences may be lost from record and others may have wrongly presumed to have been granted or may be total inventions.)

Original source is;

• National Archives C143/2/43 (Chancery: Inquisitions Ad Quod Damnum, Henry III to Richard III c1216-c1485)

(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. Licentia is best translated as 'freedom to' not 'permission'.)
