Origin of the Name MacMorrow
family history was found in the allfamilycrests.com archives. The names McMorrow and McMurrough are among the most illustrious in Ireland . It was McMurrough who sought help from Henry II and thus was the instigator of the Anglo-Norman invasion. His desendant Art McMurrough, 1357-1417, also King of Leinster , did much to remove the opprobrium, consequently glorifying the name by his continuous and successful resistance to English invaders. Art McMurrough was styled Kavanagh. This important Sept became divided into several sub-septs. The McMurroughs, the Kavanaghs and the Kinsellas descend from Murchadha, translated as 'Murrough', grandfather of King Dermot McMurrough. The latter, except in the case of the Chief of the name, who is now styled O'Morchoe, all became Murphy and Davis respectively. The original surname is now rare, McMurrough or McMorrow being seldom found today outside County Dublin .
The MacMorrow coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all MacMorrow descendants.
