From this instrument (of which there are two summaries iu the Extracts from 

 the Duiske Registers which we call E) the seal has disappeared.' Its date can be 

 fixed with some precision, as we know something of nearly all the persons 

 mentioned, and we shall find that it must be placed between 1162 and 1165. 



Dermot MacMnrroiigh, King of Leinster, died in 1171. 



Dermot O'Ryan (Diarmait L'arrian), Chief of Idrone (Uanronai), a liegeman of 

 King Dermot, was slain in 1171.' Idrone is now a barony in co. Carlow, but at 

 this time included that part of the dioceses of Kildare and Leighlin which is to 

 the west of the river Barrow. Killenny (Ceall Lainne) was in the O'Ryan country, 

 in the townland of Old Abbey, now Barrowmount, in the civil parish of Grange 

 Silvoe^ and the diocese of Leighlin. No remains of the abbey buildings can now 

 be traced, but they were probably of no great magnitude or consequence at any 

 time. 



Only a few of the lands granted by Dermot O'Ryan for the purpose of the new 

 monastery can be identified. Dun inni is Doninga, a townland in the parish of 

 Grange Silvae ; Druim ro is now Mount Loftus in the parish of Powerstown. 



The first witness to the Charter, Laurence, archbishop of Dublin, was the 

 famous St. Laurence O'Toole (1162-llHO). He was King Dermot's biother-in- 

 law, which accounts for his presence. 



Donat, bishop of Leighlin, the date of whose accession is uncertain, but 

 probably prior to 1152, died in 1181. Inasmucii as KilLnny was situated in the 

 diocese of Leighlin, the attestation of the bishop of that diocese was specially 

 desirable. 



Felix, abbot of Ossory, is Felix O'DulIany, who was the first abbot of Jerpoint, 

 before he became bishop of Ossory in 1178. He died in 1202, and was buried at 

 Jerpoint Abbey, where his altar-tomb, with his effigy in relief, is still to be seen. 



Murchad filius Murchada, i.e. Murrougli mac Murrough, was King Dermot's 

 brother; his son Muirclierlach died in 1193. 



Domnall Caemanach, i.e. Donnell Kavanagh, was King Dermot's illegitimate 

 son. He was brought up at Kilcavan, near Gorey iCill-Cdenihaini, and hence was 

 surnamed Caemhan-ach or Kavanagh. He is the eponymous ancestor of the Clan 

 Kavanagh. He was killed, according to the Annals of Ulster, in 1175. 



Paidin Uaheda, or O'Hea, who is described in the AnnaU of Ulster as " the 

 candle of all O'Kinselagh," is said by the same authority to have been killed in 

 1165. 



' Tliis charter h.is been rejirodiiccd in Gilbert's FarmnUtt of Natunuil Mtinuacripts of 

 Irdand {Pi. II, plate Ixiii), but the editor, by the unfortunate insertion in his printed 

 text of the name DuUke after ' monasterio,' in 1. 24," instead of the wordB 'si ibi fuit,' 

 was lead to misinterpret it as the Foundation Charter of Duiske Abbey. This is a 

 mistake which has been reproduced in many Itooks. As we shall see, the abbey of 

 Duiske was nut founded for nearly forty years after the date of this charter, in which 

 the name ' Duiske ' or ' Graigue na managh ' does not occur. 



' Orpen, Irelatid utider the Kormans, i, 231. 



' The exact position of KUIenny wa.s first determined by Carrigan (iv, 279).
