  Notes	Conn Cétchathach legendary High King of Ireland Ireland Native Conn Cétchathach Ceadcatha was born in Ireland. Conn Cétchathach, the legendary 2nd century High King of Ireland is remembered as one of seven sons of the Ard Ri (king of Tara), Feidlimid Rechtaid,. The kings of Tara were the over-kings, or High Kings of Ireland. [1] His mother is sometimes said to have been "the daughter o the king of Denmark"[2] In Irish mythology, Conn's mother is remembered as Medb Lethderg, a legendary goddess of Sovereignty associated as the spouse of nine successive kings of Tara; the Medb of the Connachta of the Ulster Cycle. [3] [4] Conn Cétchathach was the ancestor of the Connachta. Conn's descendant, Niall Noigiallach was the founder of the Uí Néill dynasties, which dominated Ireland in the early Middle Ages. [5] Conn Ceadcathach, Conn of the Hundred Battles was so named for his many battles fought and won; sixty battles against Cahir Mór, King of Leinster (109th Monarch of Ireland) whom he slew and succeeded in the Monarchy; one hundred battles against the Ulsterians; and one hundred more in Munster against Owen Mór. Conn and Owen (Eogan) Mor divided Ireland between them; all the country north along the long ridge of hills, Esker Riada, running between Dublin and Galway, Leath Cuinn belonged to Conn; the southern portion, Leath Mogha to Owen Mór. [6] [7] [8] He had two brothers, Eochaidh Fionn-Fohart and Fiacha Suidhe, who, to make way for themselves, murdered two of his (Conn Ceadcathach's) sons named Conla Ruadh and Crionna; but they were by Conn Ceadcathach's third son, Art Eanfhear banished, first into Leinster, and then into Munster, where they lived near Cashel. They were seated at Deici Teamhrach (now the barony of Desee in Meath), whence they were expelled by the Monarch Cormac Ulfhada, son of Art; and, after various wanderings, they went to Munster where Oilioll Olum, who was married to Sadhbh, daughter of Conn of the Hundred Battles, gave them a large district of the present county of Waterford, a part of which is still called Na-Deiseacha, or the baronies of Desies. They were also given the country comprised in the present baronies of Clonmel, Upper-Third, and Middle-Third, in the co. Tipperary, which they held till the Anglo-Norman Invasion. From Eochaidh Fionn-Fohart descended O'Nowlan or Nolan of Fowerty (or Foharta), in Lease (or Leix), and Saint Bridget; and from Fiacha Suidhe are O'Dolan, O'Brick of Dunbrick, and O'Faelan of Dun Faelan, near Cashel. Conn of the Hundred Battles had also three daughters: 1. Sadhbh (or Sabina), who m. first, MacNiadh, after whose death she m. Oilioll Olum, King of Munster. 2. Maoin; and 3. Sarah (or Sarad), m. to Conan MacMogha Laine. Conn reigned 35 years; but was at length barbarously slain by Tiobraidhe Tireach, son of Mal, son of Rochruidhe, King of Ulster. This murder was committed in Tara, A.D. 157, when Conn chanced to be alone and unattended by his guards; the assassins were fifty ruffians, disguised as women, whom the King of Ulster employed for the purpose.[9] Children Conla Ruadh Crionna Art Eanfhear, the 112th Monarch of Ireland, in the second century of our era. Sadhbh (or Sabina), who m. first, MacNiadh, after whose death she m. Oilioll Olum, King of Munster. Maoin; and Sarah (or Sarad), m. to Conan MacMogha Laine.[10] Research Notes No dates associated with this person are directly known. A number of secondary sources have attempted to estimate chronologies of early Irish history, but they do not agree with each other and the estimates could easily be off by centuries.
