The High Middle Age          1000-1300 AD 


Dermot MacMurrough

His Irish name was Diarmaid Mac Murchadha and he was known later in his life as Diarmaid Nan Ghaill, which translates to mean Diarmaid of the Foreigners. His English name was Dermot MacMurrough and he was born on the first of May in 1110 AD.  He was unexpectedly crowned as the King of Leinster Province in 1126 AD after the deaths of his Father and Brother the Kingdoms ruling predecessors. He reigned as the King of Leinster until 1172 AD. His rise to the throne was opposed by many including the High King of Ireland Toirdelbaach Ua Chonchhobair because Ua Chonchhobair opposed any potential Murchadha who could ascend to the throne of Leinster and as a traditionally popular favorite of the people go on to become theHigh King of Ireland.

 Under the laws of the time Dermot could take two wives. His first wife was Mor Ui Thuathail, and together they had daughters Aoife and Conchobhar.  They also had two sons named Domhnall Caomhanch and Eanna Ceannsealach. His second wife was Sadhbh of Ui Fhaolain and together they had a daughter named Orlaith. High King Toirdelbaach Ua Chonchhobair was intent on undermining Dermot's reign andsent for a King from one of his allied Kingdoms to take his army into Leinster and attack the people, intending to destroy the economic base, slaughter the livestock, causing starvation and great hardship for the people and Dermots Government. 

The leader of the attack was King Tiernan O'Rourke who succeeded in driving Dermot off the Leinster throne in 1129 AD.  Dermot was able to regain the throne and drive O'ourke back and out of Leinster in 1132 AD with the help of loyal clans of the Ui Cheinnselaig tribes that were traditionally allied to the Kings of Leinster.  Dermot used the next twenty years of his reign to strengthen his military and political power. He apprehensively submitted to High King Toirdelbaach Ua Chonchhobair, winning his confidence and friendship while rebuilding his own Kingdom in the aftermath of O'Rourke attack on Leinster.  By 1152 O'Rourke seeing the change of his relationship with the High King fell from favor and became a problem for Toirdelbaach Ua Chonchhobaira.  Dermot recognized that O'Rourke had become a problem for the High King and developed a plan of attack with the help of O'Rourke brother In-law and with the aid of the High Kings armies attacked O'Rourke Kingdom.  Dermot captured O'Rourke wife and kept her Hostage at his Fern Castle to serve as reason for continued ongoing hostilities between a ruined O'Rourke and the now powerful King of Leinster.

 Another fifteen years passed and Dermot saw his daughter Orlaith wed Domhnall Mor the King of Munster.  Many of the clans with different tribal roots had ongoing disputes with their traditional enemies and with time they organized their skirmishes into better organized forays into each other territories.  This caused regional instabilities all over the Kingdoms of Ireland and eventually led to Nation-wide tribal warfare.  As the situation broadened it spread into Leinster and in 1167 AD, Dermot was once again ousted from the throne with little sign that he would be able to stop the warring parties and regain order or the throne of Leinster.  Determined to put an end to the chaos and end it permanently by restoring his position on the Leinster throne. Dermot traveled to England and asked King Henry II, King of England for help.  Dermot took an oath of allegiance to Henry II and was given an Anglo-Norman army under the leadership of a Regent named Richard Le Clare Fitzgerald, second Earl of Pembroke.  Le Clare was commonly known as Strongbow, and as an aggressive upwardly mobile regent who also had his own agenda that differed from Dermot and the expectations of King Henry II. 

Strongbow landed his Anglo-Norman army in Ireland in 1170 AD and Diermot helped the invaders capture Dublin- immediately ending tribal in-fighting in Leinster and restoring order. MacMurrough soon recognized that Le Clare was making unnecessary advances while amassing great reserves of pillaged gold and silver and large tracts of State forced land evictions taken from uninvolved land owners apparently intending to etch out his own domain in Ireland. In order to protect the future of Leinster as an Irish Kingdom and guarantee his part in Leinsters future, Dermot arranged the marriage of his daughter Aiofe to Le Clare.  MacMurrough was saved with order restored in his Kingdom albeit his Kingdom was now in the hands of his daughter and a foreigner, and shortly after in 1172Dermot died leaving Strongbow and Aiofe to rule Leinster.

The Rise Of The Kavanaugh  / Return Of MacMurrough  Power


Henry II soon heard of Le Clare many successes and concerned that Le Clare notoriety may draw the support of those subjects who opposed his rule Henry II put together another invasion force while discrediting the efforts of Le Clare invasion of Ireland as a failed attempt now needing his personal ntervention to correct the situation.  Henry took his army there to intervene in Le Clare expansionism and ordered Le Clare to take his army home to England and surrender all his gains as tribute for him.  Henry II warned that any soldier that did not leave would lose allrights of citizenship including forfeiture of their family lands and wealth in England. 

Le Clare withdrew his Army and restated his allegiance to Henry II, who now saw that the political situation was stable with the presence of MacMurrough at Le Clare side.  Henry returned to England leaving Strongbow installed as Regent of Ireland.  Shortly after Diermot MacMurrough death Henry II recalled Strongbow to his service at home to deal with revolts elsewhere in England during which Strongbow further established his loyalty to Henry II Crown. As a reward Henry II returned him to Ireland to serve as the Lord Protector of all Ireland where he served until his retirement in Wexford. Strongbow eventually died in June 1177AD.  His wife Aiofe immediately remarried Domhnal Caomhanach MacMurchada the son of her half Sister Orlaith and Donald Mor, The King of Munster. 

 Donhall Caomhanach MacMurchada served as the King of Leinster from 1171 to 1241.  He made contributions to the Catholic Church commissioning several Romanesque designed Church?s and Chapels at the Cistercian Abbey in Baltinglas,at St Mary?s Abbey in Fern?s at Monasteries in Glendalough and Kileshin.  He also sponsored several Convents at St Mary?s of Dublin, Aghade in Carlow and Kilculhen in Kilkenny. The marriage of Aiofe and Donhall Caomhanach MacMurdhada served as the means for the successful return and restoration of the MacMurrough blood line to the throne of Leinster and a MacMurrough having a chance to once again serve as the High King of all Ireland.

 The MacMurrough and Kavanagh relationship lasted for several centuries during which time the MacMhadoc Sept succeeded in climbing in status to a distinct branch of the MacMurrough.  The MacMhadoc became quite important and established in southern parts of Wexford in an area now known as the Country of the MacVadogs.  The Clan hereditary territory was continually encroached upon and threatened in later occupations and with land evictions and land seizures entwined with changes in law forcing them further north to its latest area of Patrimony, Gorey Barony. The MacMhadoc name evolved as family members spread out across Leinster into North Wexford to adjacent areas Westward and into the South of Wicklow, Arklow Town and Dublin were they are mostly located today under the names off Weadick, Waddock, Wadock, Wedock, Waddick, Weddick, Weadock, Waydock Waedock and sometimes Vaddock.
