Fearghal Ó Taidg an Teaghlaigh Fearghal Ó Taidg an Teaghlaigh , Chief of the Name , Marshal and bodyguard of King Cathal Crobhdearg Ua Conchobair of Connacht and his successor , Aedh , died 1226 . Background . Ó Taidg was a descendant of King Tadg mac Cathal of Connacht ( reigned 925 – 956 ) , and was thus distant related to the Ua Conchobair ( O ' Connor ) ruling dynasty . His family were one of a number of septs of the Síol Muireadaigh , which included clans such as Geraghty ( Mac Airechtaig ) , Moran , Flanagan , Mulrooney , and MacDermot . Two early members of the family are listed in the Annals of the Four Masters " sub anno " 965 and 1048 : The Ó Taidg family ruled an area in mid - County Galway , which was called Clann Taidg after them . It appears to have come into existence during a wave of expansion by the Uí Briúin in the middle decades of the 10th century . Previously part of Uí Briúin Seóla , the Ó Taidg ' s are believed to have become its lords sometime in the mid - 11th century . However , by the end of the 12th century it was said to have been seized by Donn Cathaig Mór Mac Airechtaig of Síl Muiredaig . By 1241 much of the area was seized by Meyler de Bermingham , who made Athenry the seat of his lordship . An Teaghlaigh . By the early 12th century the family added the suffix " an Teaghlaigh " to their surname . It derived from the fact that the family were household chiefs and bodyguards of the Kings of Connacht . The earliest record of the term occurred in 1132 , when " The castle of Bun - Gaillmhe ( Galway ) was burned and demolished by a fleet of the men of Munster ; and a great slaughter was made of the people of West Connaught , together with Ua Taidhg an Teaghlaigh , and many other noblemen . " King Cathal . Fearghal ' s lord and king was Cathal Crobhdearg Ua Conchobair , who fought for the kingship of Connacht from the 1180s , succeeding in becoming undisputed king in 1202 . As both his bodyguard and chief of his household – much like a royal Marshal such as John Marshal ( c . 1105 – 1165 ) – Feargal would have been at Cathal ' s side for many years , especially when on campaign . The war of 1225 . Cathal died in 1224 , and succeeded by his son Aedh who was almost immediately beset with problems . Donn Óge Mag Oireachtaigh had been deprived of his lands by Aedh , and now sought the help of Domnall Óg Ó Néill of Tír Eógain . In 1225 Ó Néill invaded and set up a new king . Only a few of the Síol Muiredaig " namely , Mac Dermot , David O ' Flynn , & . " stayed loyal to Aedh . Aedh then resolved " to repair to the English to the Court of Athlone ; for it happened , fortunately for him , that the chiefs of the English of Ireland were at that very time assembled there , and the greater part of them were friendly to him , on his father ' s account as well as on his own , for both had paid them wages for military services , and had been bountiful towards them . The English received him with joy , and kept him among them with much affection for some time afterwards . He then engaged in his cause the Lord Justice , and as many of the chiefs of the English of Ireland as he considered necessary , together with Donough Cairbreach O ' Brien , and O ' Melaghlin , with their forces . " In the warfare that followed engagements occurred all over Connacht , from Turlough in County Mayo to Meelick in County Galway . Coolcarney was plundered , after which some of its people " fled to Duvconga , but the greater part of these were drowned ; and the baskets of the fishing weirs were found full of drowned children . " Restoration and the death of Niall . Aedh was eventually restored , but the price was giving " to the English the chiefs of his people , as hostages for the payment of their wages , as Flaherty , O ' Flanagan , Farrell O ' Teige ( i . e . , Fearghal ) and others of the chiefs of Connaught , who were subsequently obliged to ransom themselves . " No sooner had the English left than the sons of Ruaidri O Connor rose up in revolt again . In the subsequent Battle of Ardrahan " Niall , the son of Farrell O ' Teige , and others , were slain ; but the man who slew Niall O ' Teige , i . e . the brother of Colen O ' Dempsey , was slain himself also . " Eventually , a truce was declared , of which the annals say " This was a necessary tranquillity , for there was not a church or territory in Connaught at that time that had not been plundered and desolated . An oppressive malady raged in the province of Connaught at this time : it was a heavy burning sickness , which left the large towns desolate , without a single survivor . " Death . Despite this , warfare continued again next year . Fearghal was killed in County Sligo " by Donslevy O ' Gara " , who had been forced to make peace with King Aedh the year before . King Aedh was killed in 1228 and succeeded by his cousion , Aedh mac Ruaidri Ua Conchobair . Descendants . Of Fearghal ' s family there are few notices in the subsequent annals . A bald statement for 1251 state " Muiredach O Taidc died . " . In 1429 it was noted that " Melaghlin , son of Conor Anabaidh O ' Kelly , who was the son of the Lord of Hy - Many , was slain with one cast of a javelin , by John Cam O ' Teige , one of O ' Conor ' s people . " After this , the family fade from history .
