(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'.)

Seagrave , Nicholas (d. 1321)’
Seagrave was one of Edward II's staunchest supporters at the outset of the reign. In the crisis of March 1308 he was appointed custodian of Northampton Castle, and even after the banishment of Piers Gaveston, he was one of four royal councillors singled out to be removed from the court by the Northampton parliament of August 1308. Despite this, there is little evidence that Seagrave played a major role at court. He is very rarely found among the witnesses to royal charters before 1312, and his vilification in 1308 may have had more to do with his adherence to Thomas, earl of Lancaster, still loyal to the king at this time, than to his own activities. On 12 March 1308 Seagrave had been appointed marshal of England. (Hamilton)
