Show ContentsMagrath 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 Magrath 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 Magrath family

The surname Magrath 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

United States Magrath migration to the United States +

In the 18th and 19th centuries hundreds of thousands of Irish people immigrated to North American shores. The early settlers were enticed by the promise of their own land, but they were moderately well off in Ireland when they decided to emigrate. Therefore, they were merely carrying out a long and carefully thought out decision. The 1840s saw the emergence of a very different trend: thousands of extremely desperate people crammed into passenger boats hoping to find any type of opportunity. The Irish of this decade had seen their homeland severely stricken by crop failures which resulted in widespread disease and starvation. At whatever time the Irish immigrants came to North America, they were instrumental in the rapid development of the emerging nations of the United States and what would become known as Canada. An exhaustive search of passenger and immigration lists has revealed many persons bearing the name Magrath, or one of its variants:
