A brief history of the Clann Chaomhánach
The outstanding historical leaders of our illustrious Clan are, in chronological order, Diarmaid Mac Maol na mB?(early 1000s ?1072), Diarmaid McMurrough (MacMurchadha) (1110 ?1171), his son Domhnall (1128 ?1175), Art Óg McMurrough Caomhánach (1357 - 1417) and Domhnall Spáinneach Caomhánach (1550 - 1632).
The stronghold of the U?Cheinnsealaigh (Hy Kinsella) Clan which subsequently adopted the Caomhánach name was in South East Leinster, encompassing the modern counties of Wexford and Carlow, with parts of Counties Wicklow, Kilkenny and Laois.
The U?Cheinnsealaigh initially rose to power in Leinster under a chieftain called Diarmaid Mac Maol na mB?who became king of Leinster and also of Viking Dublin, in 1032. He subsequently ruled over the Isle of Man and exercised influence in Western Scotland and Wales, as well as assisting the future King Harold of England. Subsequent to Harold’s defeat by the Norman William the Conqueror his sons fled for help to Mac Maol namB? He was the most powerful King in Ireland of his time up until his death in battle in 1072.
Following Mac Maol na mBó’s death, the U?Cheinnsealaigh were embroiled in various conflicts involving the quest for overall power in Ireland initially by the by the O’Briens and subsequently by the O’Connors.
Mac Maol na mBó’s greatgrandson, Diarmaid McMurrough (1110 ?1171; see separate article under 'Origin' on Home Page) was no sooner elected chieftain of the clan at 16 years of age in 1126, than his territory was invaded and ravaged by the power-hungry O’Connor clan of Connacht together with the malevolent Tiarnan O’Ruairc, King of Breffni, who was thereafter Diarmaid’s bitter enemy. Some years later these enemies decided to destroy him and Diarmaid was forced to seek assistance from overseas in 1166.
Diarmaid hired Norman-Welsh mercenaries, under a leader known as Strongbow, Earl of Strigoil (and Pembroke). Strongbow was offered the hand of Diarmaid’s daughter Aoife and Diarmaid further promised the mercenaries territory in South Wexford, which belonged partly to the Norse and partly to an Irish clan which had betrayed him earlier.
The main body of these mercenaries arrived in 1169, and having recovered his ancestral territory with their assistance, Diarmaid was about to expand his conquests, probably with a view to replacing O’Connor as High King, when he was struck down by a mortal illness in 1171.
Following the death of Diarmaid
McMurrough (MacMurchadha) the Norman barons began to strike out and seize Irish
territories for themselves, whereupon the Norman King Henry II came over with a major army principally to
ensure that his barons did not carve out an independent Norman kingdom.
Domhnall’s successors were recognized as the leading family in Leinster by the other Irish clans and continued to claim the Kingship of Leinster right up to the beginning of the 17 th century. However, their ancestral territories were under continual threat, initially from Norman, and later English, settler aggression. Preserving their hold on their birthright meant a struggle for survival over the succeeding centuries with varying degrees of success against a ruthless enemy who used every means possible, including regular resort to murder, in order to seize Caomhánach ancestral territory.
Art Óg Caomhánach (1357 - 1417) succeeded his father Art Mór (who died mysteriously in English custody) in 1377 and began a series of campaigns which enabled him to recapture Caomhánach ancestral territory which had been lost.
King Richard II of England, attempting to restore his control over the Caomhánachs and other Irish
Clans, landed with one of the largest armies ever seen in Ireland at Waterford City in 1394.
Upon Art Óg’s death, his son Domhnall received the Carlow lands west of the Blackstairs mountain range, while his other son Gerald received the lands in Wexford, east of the mountains. The descendants of Gerald's son, Domhnall Reagh, became the senior ruling line of the Caomhánach Clan. Domhnall Reagh's son, Art Bui, and grandson Murtagh, succeeded in maintaining the Clan's independence despite continuing settler encroachment.
The Chieftainship of the Clan continued in the senior line through the descendants of Domhnall Reagh.
The protection of Clan lands was only achieved at the expense of continuous warfare, with Cahir Carach Caomhánach being killed in 1538
and his son Donnchadh executed in 1583. Donnchadh's son, the famous Domhnall Spáinneach, was regularly in rebellion and was an ally of
the Great Hugh O’Neill during the Nine Years War (1594 -1603). Though Domhnall was finally forced to come to terms with the English
administration after the Battle of Kinsale in 1601, he retained a substantial part of his lands and was feared by the settler foes up
until his death of old age in 1632.
Domhnall Spáinneach's son, Sir Morgan, continued the fight for his ancestral territory as a leader
in the 1641 Rebellion during the course of which he was slain in battle in1643. Sir Morgan's sons, Domhnall Óg and Charles, continued
the fight with their father's regiment for the Catholic Confederacy until the rebellion was finally crushed by the armies of Oliver
Cromwell in the early 1650s.
