 To the archbishop of Armagh. Mandate to decide the matter between 
 the bishop and chapter of Derry and the heirs of Richard de
 Burgo, earl of Ulster. As appears by the petition of bishop
 Michael, his predecessor, Geoffrey, and the chapter had a dispute
 with Richard touching the right of patronage of certain churches
 and lands and rights belonging to the bishopric, and the earl relying
 on his temporal power got the better of the bishop and chapter, who
 suffered heavily, but verbally agreed that the earl and his heirs
 should hold the portion and temporal jurisdiction which they had
 in the city of Derry, and also the advowson in certain places, and 
 divers tenements belonging to the church of Derry, paying a very
 small yearly pension to the bishop. The said earl has held
 these for twenty years, to the great injury of the see, and as he
 is now dead, bishop Michael has petitioned the pope to compel the
 earl's heirs to make restitution. Witnesses are to be summoned 
 and necessary orders made and enforced." [Theiner, 237]

 1971/72 CLOGHER RECORD, in an article entitled "The Register of 
 Clogher" by K.W. Nicholls:
 
 "....Then the church of Clogher was ruled by Nicholas MacCathassayth, 
 archdeacon of Clogher, who was elected in the monastery of SS. Peter 
 and Paul at Clones on the vigil of St. Matthew the Apostle 1319 
 [February 24, 1320, NS] and consecreted in the monastery of Lisgoole 
 by the venerable Fathers Michael [MacLachlainn], bishop of Derry, 
 Thomas, bishop of Raphoe, and Patrick, bishop of Tir Briun. ...."
 
 (The Register was compiled between 1520 and 1525, and then updated 
 sporadically until about 1575. It disappeared in the 17th Century, 
 but numerous extracts of it survive, and Nicholls was able to 
 reconstruct most of it.)
