Show ContentsMcGrew History, Family Crest & Coats of Arms

All Irish surnames have underlying meanings that can be traced back to their fullest points when the names first appeared in a Gaelic form. The name McGrew originally appeared in Gaelic as Mac Graith or Mag Raith; these are both derived from the personal name Craith which literally means "to weave" and in this case is an occupational name too. The Mac or Mc prefix would denote "son of the weaver." 1

Anciently the family claim descent through O'Sullivan Mor which explains the stag (or antelope) in the fourth quarter of the shield. In turn, the O'Sullivans descend from the Heber line of Irish kings. 1

Early Origins of the McGrew family

The surname McGrew was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where they held a family seat from ancient times. They were the hereditary poets to the O'Briens of Thomond. The family is still found here, but present day descendants usually hail from Tipperary and Waterford. Another branch was located at Termon MacGrath on the borders of Donegal and Fermanagh. 2

The MacGraths were Chiefs in the County of Waterford since very early times. A sub-branch was located at Ballynagilty in Waterford where Philip MacGrath was the progenitor. 1

This latter branch of the family produced Thomas McGrath of Ardagh, near Youhal, co. Cork who had four sons and twelve daughters. Thomas was descended from the Ulster M'Graths of Clanaboy, who were of the race of Clan Colla and were men of influence in County Waterford. Two of the sons emigrated to the Americas: Alderman Thomas McGrath of Montreal (died 1864); and Denis MacGrath of New York (died in 1846.) 1

McGrew migration to the United States +

Irish families began leaving their homeland for North America in the late 18th century. These families were usually modestly well off, but they were looking forward to owning and working on a sizable tract of land of their own. This pattern of emigration continued until the 1840s when the Great Potato Famine sparked a major exodus of destitute and desperate Irish people. These people were not leaving for a grant of land in North America because by this time the East Coast had reached its saturation point and free land was scarce. They were merely looking to escape the disease, starvation, and hopelessness that Ireland had fallen into. Although these unfortunate immigrants did not receive a warm welcome by the established populations in the United States and what would become Canada, they were absolutely critical to the rapid development that these two nations enjoyed. They would help populate the western lands and provide the cheap labor required for a rapid industrialization. An examination of passenger and immigration lists has revealed many early bearers of the name McGrew or one of its variants:
