also showed that moccu in Old Irish was represented by mv.coi or mac[i m-ucoi 

 in the Ogham inscriptions, and that the corresponding people-name, where it 

 could be identified, belonged to the class of collective names which I have 

 ventured in this paper to designate as the second order. With a xievt to 

 testing these deductions more fully, I have brought together all the examples 

 of mucoi and 77ioccu. which since then I have been able to collect. The result 

 has been to confirm the deductions of my paper in Eriu. I have found no 

 conflicting instance. In many cases, the corresponding people-name has not 

 yet been discovered ; but since it appears fairly certain that the formula always 

 testifies to the existence of an ancient population-group whose name must 

 have embodied the eponym found after mv.coi or moccu, I give here the whole 

 list of examples. 



43. If I am correct m referring mocni Mich to Eli, and moccu Echctch 

 {Eckdacli) to Dal Echach = Fothau't, these instances, together with moccu Baird, 

 appear to indicate that the formula was also applicable in the case of people- 

 names of the first order. The rarity of the instances is a matter of course, 

 considering that but few names of the first order were preser-\'ed, and that of 

 these few a number, like Erainn, Lagin, eompi'ised subdivisions of the second 

 order. It is even probable, as Corcu Sogin beside Sogin suggests, that the 

 collective formula could be appUed to the older names treated as eponyms.

- This identificiition is hardly doubtful. The inscription belongs to the barony of Trughanacmy, 

 Co. Keny. The Altraige were a subdiTision of tlie Ciarraige, their eponymous ancestors being (gs.) 

 Alta, a descendant of Ciara, also named Mug Taeih, eponymous ancestor of the Ciairaige, according to 

 the genealogists. The Altraige inhabited part of the lands of CiaiTaige Luachra and Corcu Duibne. 



' Dal Coirpri, one of the four primary dirisions {cethri primsloiniite) of the Lagin. They seem to 

 have been situated in East llunster, of which a large part had once, it was believed, belonged to 

 Leinster. Of DSl Coirpri were the families of TJa Eiain (Ryan) and Ua Diiibidir (Dwyer), noted 

 East Munster surnames. The inscription, however, belongs to East Miiskerry barony, Co. Cork. 



' Conaille (cp. Coualneos fines. L. Arm.) = *Ciinovalinion. The Conaille of Muirthemne may be 

 regarded as neighbours of the Isle of Man, where the inscription is found. 



= This and the three following inscriptions are from the barony of Corcaguiny = Corcu Duibne.
