at places along the whole coast from near Bray to Arklow. 1 From another 

 great-grandson were descended the Ui Loppin or the Ui Lapen of Cell 

 Kannairech, now Kilranelagh, to the west of the Wicklow Mountains near 

 Baltinglas. 2 In other cases a later sept, claiming descent from Nia Corb, 

 intruded, as, for instance, the Ui Briuin Cualann near Bray, 3 the 

 Ui Mail, who have left their name in the Glen of Imaile, the Ui Enechlais 

 (i FortuatJudb Laigen) in the southern part of the barony of Arklow, 4 and 

 still later, after the expansion of Ui Cennselaigh, the Ui Fedlimid and Sil Elaigh 

 in the district about Eathgall. 6 But the greater part of the territory ruled 

 by the descendants of Messi Corb was from an early time known as the 

 Fortuatha Laigen, and this name, in our present quest, is very significant. It • 

 means " the stranger tribes of Leinster." 6 These were unfree tribes seated at 

 both sides of the "Wicklow Mountains, including, at any rate, the valleys of 

 Glendalough and Imaile 7 ; and as the free septs of Ui Garrchon and Ui 

 Enechlais are stated to have been in the Fortuatha, we must suppose that at 

 one time the Fortuatha included the larger part, if not the whole, of southern 

 Wicklow. Moreover, we have authority for saying that these " Stranger 

 Tribes " included the remnants of the Galians, and that they were ruled in 

 historical times by kings whose descent was traced from Messi Corb. For, in 

 the first place, the Galians appear to have joined in the revolt of the Aithech 

 Tuatha, or vassal peoples, and on its temporary success to have received 

 Leinster as their share. Cairpri " Cat-head," the leader, was perhaps a Galian ;

5 Dergne or Deilgne Moghoroc, i.e. Delgany (Ann. Ulst. and Four Masters, 1021), 

 and Tech ConaiU, i.e. Powerscourt (Mart. Oengus, 26th May), were in Ui Briuin 

 Cualann. 



1 Inis Mocholmoc, now Inch, was in Ui Enechlais (Mart. Oeng. November 14), and 

 Ui Enechlais was in the Fortuatha Laigen (ibid., ed. 1880, p. 77). 



' Rathgall in the thirteenth century was in the deanery of Offelimy, which included 

 not only the parishes of Tullowjihelim, Rathvilly, and Clonmore to the north, but also 

 those of Aghowle and Ardoyne to the south (Cal. Docs. Irel., vol. v, p. 251). It is now 

 included in the barony of Shillelagh, and the name Offelimy is preserved only in the 

 parish of Tullowphelim. 



So O'Donovan, Book of Bights, p. 207, n. Hennessy, indeed, renders hi fortuathaib 

 Laigen, " on the borders of Leinster," Ann. Ulst., 708. But Glendalough and Imaile 

 were not on the borders of Leinster, and there were many other Fortuatha who were not 

 on the borders of any territory, but who always seem to have been unfree tribes, not 

 descended from Milesians ; e.g., the Fortuatha near Fermoy descended from Mog Ruith 

 the Druid, Book of Rights, p. 78 n. ; the Fortuatha of Ailech, to whom significantly 

 would seem to be ascribed the original erection of the Griandn Ailigh, ib. 120 n. ; the For- 

 tuatha of Uladh, ib., p. 173 n. ; the Fortuatha Connacht in Irrus Domnon, also a Firbolg 

 tribe ; and the Fortuatha Breg, or Luagni of Tara, again an unfree tribe.
