                   ANCIENT IRISH PROPER NAMES. 

AT this stage it may be well to give for the reader's information the 
following Irish proper names and adfixes: Aodh [ee], anglicised Hugh, 
was one of ths most frequent names of Kings and Chiefs among the Irish, 
the word signifies fire, the Vesta of the Pagan Irish, and was probably 
derived from the religious worship of the Druids.  This name has been 
latinized Aedus, Aedanus, Aidus, Aidanus, Hugo, and Odo, and is the 
root of Hughes, MacHugh, Hodson, Hudson, etc.

   BRIAN is derived from bri, strength, and an, very great, meaning a 
warrior of great strength, or brian may be derived from bran, a 
mountain torrent, which implies powerful strength.  Bran, in this

Bryan, Bryant, Byrne, Byron, O'Brien, O'Byrne, etc. 
   CAIRBRE, from corb, a chariot, and ri, a king, signifying the "ruler

   CATHAL [cahal] signifies "a great warrior:" and is derived from

   CATHBHAR [cah-war] signifies a "helmeted warrior:" from cathbhar, a 
helmet; but some derive it from cath, a battle, and barr, a chief.  
This was a favourite name with the chiefs of the O'Donnells of 
Tirconnell; because, it is thought, of their lineal descent from Conn 
of the Hundred Battles (in Irish called, Conn Ceadcatha), the 110th 
Monarch of Ireland, who lived, in the second century.  It is, however, 
probable that they assumed the adfix cath, in commemoration of that 
illustrious ancestor.

of cu, a hound (as applied to a swift-footed warrior), and from all, 
great, or mighty.

or con, as above, and cobhair [cowir] aid.  The name has been 
angliciaed "Conn," and latinized "Cornelius" and "Conquovarus;" and the 
root of the sirname Connor, O'Conor, and O'Connor.  Wherever cu, a

sometimes inflected Ullain: Irish "Ulster"), Cumidhe (Midhe [mee]: 
Irish, "Meath"), Cu-Ulladh: meaning, respectively, "the warrior of 
Connaught," "the warrior of Meath," "the warrior of Ulster," etc. It 
may be here observed that Ulladh, meaning the  province of Ulster, but 
now represented by the counties of Down and Antrim, was so called 
because it was the territory into which the ancient Ulla, were driven 
by the three Collas, in A.D. 333.  The name Cuchonnacht has been 
anglicised "Connor" and "Constantine." 
   CONN (latinized "Quintus," and anglicised Quinn) is derived from

swift-footed warrior.
