General Notes

Duach Dalladh-Deadha (Duach, King of Ireland) was the 91st Monarch of Ireland
and (except for Crimthann, the 125th Monarch) was the last of 33 Monarchs of
the line of Heber that ruled the Kingdom, and only one more (Brian Boroimhe)
came to the Monarchy as the 31st generation from this Duach. The
Clan-na-Deaghaid settled in Munster a short time before the Christian Era.
They were named "Degadians" from Deagadh or Deadha, their chief, and "Ernans"
from Olioll Earon, being expelled from Ulster by the race of Ir (or the
Clan-na-Rory) went to Munster, where they were favorably received and had
lands allotted to them by Duach. According to various historians, the
Clan-na-Deaghaidh or Ernans, became very powerful, and were the chief military
commanders of Munster, as well as masters of nearly the entire country. Some
of them became kings of Munster, and three of them also Monarchs of Ireland: 1.
Edersceal; 2. Conaire No'r; 3. Conaire the Second who were respectively the
95th, 97th, and 111th Monarch of Ireland. This King Conair the Second (known
as Conair Mac Mogha Laine) was married to Sarad, sister of King Art Eanfhear,
his successor to the monarchy. From this marriage came Cairbre Riada, from
whom were descended the Dalriadians, Princess of Dalriada in Ulster, and who
was also the first King of Dalriada in Scotland, of which Loarn, the maternal
grandfather of Fergus Mo'r Mac Earca - the Founder of the Milesian Monarchy of
Scotland, was the last.

Born before 178 BC in Ireland. Died about 158 BC in Ireland. Duach's reign
ended in the year 158 Before Christ, as the reign of Fachna Fathach began as
92nd Monarch of Ireland.
