The Fianna

Fenians were founded in 300 bc by Fiachadh the High King. Wile the tales of Arthurian Knights and their code of chivaley clearly belong to the midieval concept of an armed and mounted warrior of nobility or land holding class. With knight-hood only being bestowed by the King. the basis for the "Knights of the Round Table" does have a foundation in Celtic culture. It is argued that the tales of Arthur and his knights have more parralles with Fionn Mac Cumhaill and his Fianna. Irish myths not only have the Fianna but the Red Branch of Ulster, Simi-Larly, Gamhanrhide of Connacht and the Degad of of Munster. So the idea of elite bands of warriors was well established in Celtic Myth when the midieval Round Table Knights began to adorn the tales of Arthur. Art is a common Irish Kings name it has never been an English Kings name.
During the 2nd century ad the High King Conn Cead Crtchsthach established the Fianna. The Fianna being the elite body guard of the King. consisted of 25 battalions. These included: Bascna, Morna, Mican-Smoil, O'Navnan, Ronan and others from Connacht, Leinster, Munster and Ulster. The two dominate clans were the Bascna from Linster and Morna from Connacht.
In a short time the two dominate clans Bascna and Morna became rivals. Crumhaill, the Chieftain of clan Bascna and the Fiannauigeach (Fianna Captain) was challenged by Goll the Chieftain of clan Morna. During the clan war, fought at Chucha, Crumhaill was killed. Goll claimed the Fiannauigeach and led the Fianna until Finn Mac Cumaill son of Cumaill, reached the age of majority. High King Cormac Ulfhada Mac Airt, who was son of Art and grandson of Cetchathach, awarded the Finnuigeach to Finn. During the reign of Cormac Airt and the leadership of Finn Mac Cumaill, the power of the Fianna reached it's pinnacle.
The Fianna Maintained it's power from 176 to around 280 ad. It had survived through eight High Kings. Conn Crtchathach (176-211), Conaire (211-219), Art II Aionfheam (219-249), Lughaid (249-252), Fearghus (252-254), Cormac Ulfhada Mac Airt (254-277), Eochaidh (277-279) and Caribe II Linochair (279-296)
Caribe, Grandson of Cormac Mac Airt, the new High King became jealous of the power of the Fianna. He set two rival clans against one another. In the battle of Gabhra, Finn Mac Cumhaill and Clan Bascna was defeated. The Fianna was disbanded
Whether or not you are a believer in the myth some basic facts remain. These stories were passed down verbally from generation to generation. Granted the deeds were embelished, the names remain intact.

Caoilte Mac Ronan was a Fian Bard-Warrior and the Chieftain of Clan Ronan. Caoilte was the son of Ronan (Ronain) and the nephew of Finn Mac Cumhaill. He and Finn were the only two clan leaders to survive the battle of Gabhra. He was known for his skills in poetry and fleetness of foot.
There are several different spellng variations to Caoilte's name, Caolte, Kylta and Keelta. He was best known in the Acallam na Senora (Colloquy of the Ancients), Where the aged hero met Saint Patrick. The two traveled all of Ireland. St Patrick performed his ledgendary miracles as Caoilte recounted the various brave deeds of Finn and their Comrades.
It is strange that in all the extent mass of the Ossianic Literature there is no narritive of his death. Caoilte and his comrades seem to have vanished into the magic mist which encompasses their lives, Yet a popular folklore states, that Caoilte, Finn, Olson and Oscar never died. But, lie spell-bound in an enchanted cave where they wait the time to reappear and redeem their land from tyranny and wrong.
Caoilte the nephew of Finn Mac Cumaill was Stewart to the Royal house of Crtchsthach. Cheiftain of Clan Ronan and Fian Bard-Warrior.

Clan Ronan had survived two milena, as the members scattered so did the deeds of the name. History is not clear when Clan Ronan disbanded. The only account I can find is a midland sept in the Barony of Granard. This sept was dispossed by the O'Farrells in the 13th century. It was so completely scattered that, as of a century ago the name Ronan was unknown in the region.
