Deburgh History, Family Crest & Coats of Arms

The surname Deburgh was first found in County Galway (Irish: Gaillimh) part of the province of Connacht, located on the west coast of the Island, where the family name is descended from the Norman noble William Fitzadelm de Burgo who went to Ireland in the Anglo-Norman invasion of Ireland and was the succeeded Strongbow as Chief Governor.

"Robert de Burgh, Earl of Moreton in Normandy, son of Harlowen de Burgh, by Arlotta, his wife, mother of William the Conqueror, participated with his half-brother in the triumph at Hastings, was created Earl of Cornwall, and received, as a further recompense, grants of seven hundred and ninety-three manors. His son, William Earl of Cornwall, who, rebelling against the Henry I., joined Robert of Normandy, and led the van at the battle of Tenchebray. He fell into the hands of his opponents and was sent prisoner to England, where he was treated with much cruelty, and detaining him in captivity for life. He left two sons: I. Adelm, from whom descended the Burghs, Earls of Ulster, the noble House of Clanricarde, and the various families of Burke, so widely scattered over the south west district of Ireland; and II. John, whose son, Hubert de Burgh, Earl of Kent, was Justiciary of England, temp. Henry III., and one of the greatest subjects in England." 1

Great stretches of land were given to this family in the year 1177. Richard Oge de Burc, son of William, became the "Lord Justice of Ireland" under King Henry II in 1177 and was regranted the lands of his father the following year. 2

Richard Mor de Burc, the older son of William, was the ancestor of the family name Bourke or Burke. They formed several septs, the two most important having been the MacWilliam Uachtar sept of county Galway, and the MacWilliam Lochtar sept of county Mayo.

It should be noted that not all of the family were in Ireland as some were found in Knaresborough, in the West Riding of Yorkshire in ancient times. "At the time of the Domesday Survey it formed part of the royal demesnes, and was given by the Conqueror to Serlo de Burgh, Baron of Tonsburg, in Normandy, who had accompanied that monarch into England, and by whom its stately castle, now a ruin, was originally built, on the rocky heights north of the river Nidd." 3

Another noted source confirms Knaresborough as a point of origin, but has a different Norman baron: " 'Burgh' must here stand for Serlo de Burgh, a powerful Northern baron in the time of the Conqueror, who built Knaresborough Castle, and appears to have taken his name from the manor of Burgh, in Yorkshire.
