_Lancaster King of Arms_ was, as the same author informs us, so created by Henry IV. in relation to his own descent from the Lancastrian family, and the county of Lancaster assigned to him as his province; but _Edmondson_ contends "that that monarch superadded the title of Lancaster to that of Norroy, or King of the North, having, as it may be reasonably conjectured, given this province north of Trent, within which district Lancaster was situated, to him who had been formerly his officer of arms, by the title of that dukedom, and who might, according to custom, in some instances of former ages, retain his former title and surname of heraldship, styling himself _Lancaster Roy d'Armes del North_." {32} _Leicester King of Arms_ was a title similar to that of _Lancaster_, and likewise a creation to the same Sovereign, Henry IV., who was also Earl of Leicester before he assumed the crown, and was given to a person who was before that time a herald. It appears that _Henry Grene_ was _Leicester Herald_, 9th King Richard II., and in the 13th of the same reign is called a _Herald of the Duke of Guyen and Lancaster_, but prior to the coronation of Henry IV. he was certainly a King of Heralds, and so styled in a privy seal dated antecedent to that ceremony. A similar instrument of the tenth year of that monarch's reign also mentions _Henry Grene_, otherwise _Leicester King of Arms_. As it is evident that, during the reign of Henry IV., _Lancaster King of Arms_ has under that title the province of the north, _Mr. Edmondson_, with good reason, supposes that the southern province, or part of that which is now under Clarenceux, might at that time be under this _Leicester_, especially as the title of _Clarenceux_ was not in being till after the 3rd of Henry V., when, or soon after, the title of _Leicester_ might have become extinct by the death of that officer; for although _Leicester King of Arms_ went over into France with Henry V. in the third year of his reign, yet he is not mentioned in the constitutions made by the heralds at Roan in the year 1419-20.
