In 1392 Oct 24, Randulphus de Lomley, chivaler (Sir Ralph Lumley) was granted, by Richard II, (In year 16 of his reign) a Confirmation licence to crenellate Lomley (Lumley Castle)

"Licence for Ralph de Lomley, knight, to build a castle (castrum) at Lomley and crenellate it."

Granted at York, by King.

Apparently in the same terms of the bishops licence of 1389. King writes "Hutchinson very rightly points out that this licence from Richard II must have been 'intrusional or merely confirmatory'. [Bishop] Skirlaw had been forced upon the King by the Appellants in 1388, which may supply a clue to the reasons for this very unusual entry; but the exact narrative is likely to remain a mystery." [Lumley is in the County Palatinate of Durham]

(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.)
