Show ContentsGath 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 Gath 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 Gath family

The surname Gath 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 Gath migration to the United States +

The 18th and 19th centuries saw many Irish families immigrate to North America in search of land and opportunities. The largest influx of Irish immigrants to the United States and British North America came during the 1840s when the Great Potato Famine laid waste to their homeland. Hundreds of thousands left the island in an attempt to escape the starvation and disease it brought. Although the arrival of such a large number of destitute Irish was not welcomed by the established population in the United States and what would become known as Canada at the time, these Irish were an essential element to the rapid development of these growing industrial nations. They filled the demand for the cheap labor needed for the work in factories and in the construction of bridges, roads, canals, and railways. An examination of passenger and immigration lists has revealed many immigrants bearing the name of Gath or one of its variants:
