Burke or de Burgh / de Burca - Anglo Norman origins. They were originally from Tonburg in Normandy. (Descended from William Fitz Adelhm from Burgh in Suffolk ) who arrived in 1171 AD after the Anglo - Norman Invasion succeeding Strongbow as the English appointed Chief Governor in Ireland. He was granted the Ulster Province by Henry 11 the Anglo - Norman English King and much of the Connacht Province, with the family becoming Gaelic very quickly. They were in Co. Galway, Co. Mayo and Co. Sligo in the north - west of Connacht, Co. Kildare in Central Southern Leinster and Co. Tipperary and Co. Limerick in Northern Munster. English Barons, English Viscounts, Earls and Lords in Co. Limerick and Co. Galway. Many Gaelicized sub - branches were formed, including Mac David Burke in Co. Galway, Mac Hugo, Mac Gibbon,  Jennings / Mheic Sheoinin, Mac Redmond, Mac Qualter, etc. The de Burgos in the Connacht Province also took up the names, Mac William and Mac Phillip. In 1230 AD Rickarde, the son of William, controlled Galway City situated on Loch Corrib, and he continued to extend his territory by building the Dun Lure Castle on the north coast of Co. Antrim in the north - east of Ulster. In 1244 AD Walter, who was then the English appointed Earl of Ulster, founded a Friary at Newtownards in Co. Down in the south - east of Ulster. The great grandson of the original William de Burgh, William "Liath" de Burgh became the direct ancestor of the two most influential families, Mac William "Uachtar" in Co. Galway and Mac William "Iochtar" in Co. Mayo. Others were Mac Philbin (Descended from a son of Philip de Burgh,) and Mheic Sheoinin descended from John de Burgh who were in Co. Mayo, and Mac Gibbon / Mheic Giobuin (Descended from a son of Gilbert de Burgh.) In 1300 AD Richard who was then the Earl of Ulster built a Castle at Ballymote in Co. Sligo in the north - west of Connacht and in 1305 AD he also founded the Carlingford Catholic Priory in Co. Louth in the north - east of Northern Leinster. In 1314 AD Walter who was then the Earl of Ulster was the son - in - law of Robert 1st "The Bruce" the Norman Gaelic King of Scotland. In 1324 AD William built a Catholic Church at Athenry in Co. Galway in Southern Connacht, which eventually became the main burial place for the English Earls of Ulster and for the other main Irish Families in the west of Ireland, and later on during Oliver Cromwell’s Invasion his soldiers destroyed all the monuments there. In 1333 AD the then English Earl of Ulster died, and the male line died with him, as there was only a daughter left who married Edward 111’s the Anglo - Norman English King's second son, Lionel Duke of Clarence. The remaining de Burghos then changed their names to Burke and Mac William to hold onto their lands there, and they also settled into Co. Limerick and Co. Clare in the north - west of Thomond / Northern Munster. See also de Burgo, as they were originally the descendants of the Anglo Norman de Burghos / de Burca, (The Mac Williams were the English Earls of Clan Rickarde.) In Southern Leinster they were also known as the Mac Mylers and Mac Davids. In 1536 AD Grace O Malley was the Heremonian Ui Cobhthaigh Dal Cuinn Ui Briuin Pirate Queen, who was the daughter of O Malley the Irish Lord of the Isles, who had her stronghold on Clare Island in Co. Mayo in the mid - west of Connacht and she married Sir Richard Bourke who was her second husband and produced Toby who began the line of the English appointed Earls of Mayo at Carrigahooly Castle / Rock Fleet on the sea at Newport in the south of Co. Mayo built by the Burkes, and this passed to Grace O Malley who put in her followers during her year of marriage to Richard Burke. In 1542 AD after the Confiscation of all the Irish Catholic Institutions Richard de Burgo (who was known as the Red Earl of Ulster) was given the Claregalway Franciscan Friary in Co. Galway where he is buried. The Portumna Castle of the Earl of Clan Rickarde was also in Co. Galway and the ruins are still there to see as later on it passed to the English Earl of Harewood / Burkes at Claregalway in Co. Galway. Burke Castle there is also in ruins.
