Show ContentsGarth 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 Garth 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 Garth family

The surname Garth 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

Garth Spelling Variations

Irish names recorded during the Middle Ages are characterized by many spelling variations. This preponderance of variations for common names can be explained by the fact that the scribes and church officials that kept records during that period individually decided how to capture one's name. These recorders primarily based their decisions on how the name was pronounced or what it meant. Research into the name Garth revealed many variations, including MacGrath, MacGraw, MacGrauth, Magrath, Magraw and many more.

United States Garth migration to the United States +

Irish immigrants began to leave the English-controlled Ireland in sizable numbers during the late 18th century. Many of these Irish immigrated to British North America or the United States in the hopes of gaining their own tract of farmland. This pattern of migration grew steadily until the 1840s when the Great Potato Famine caused a great exodus of immigrants to North America. These immigrants differed from their predecessors in that they were desperately fleeing the disease and starvation that plagued their homeland, and many were entirely destitute when they arrived in North America. Although these penniless immigrants were not warmly welcomed when they arrived, they were critical to the rapid development of the United States and what would become known as Canada. Many went to populate the western frontiers and others provided the cheap labor the new manufacturing sector and the building of bridges, roads, railways, and canals required. A thorough examination of immigration and passenger lists has revealed some of the earliest people to arrive in North America with name Garth or one of its variants:
