Oh My God! The Statutes of Kilkenny!
In order to bring Ireland under control, the Duke of Clarence gathered a Parliament in Kilkenny last year to pass several laws called the Statutes of Kilkenny, forcing the English-Irish living in Ireland to maintain their English heritage. Apparently many of them speak Irish better than any Irishmen so as a condition of keeping their lands, they must learn English and they are forbidden to marry the Irish. Ireland is the wilderness from the point of view of England. Their remote location has contributed to the assimilation of the English-Irish (also called the Hiberno-Normans). Enforcement of the Statutes has failed, so the Duke of Clarence has given up and has gone back to England in disgust.   
Black Death: King Edward III's Plot
During the Plague years, King Edward III of England bought a cemetery near the Tower of London and supported a chapel dedicated to the Virgin Mary in gratitude of being delivered from his many close calls and probably in anticipation of further saving required from the Black Death. It was quite common at the time to make such contributions to the Church for this purpose. Now King Edward's original efforts have grown into a monastery. He has upped his contributions to about a thousand pounds sterling annually. In near present day dollars that is over 4 million dollars.

On his deathbed Edward made further grants on the scale that he had originally promised."
