Etymology of MacRath

What does the name MacRath mean?

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 MacRath 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." (O'Hart)

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. (O'Hart)

Early Origins of the MacRath family

The surname MacRath 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. 1

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. (O'Hart)

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.) (O'Hart)

Migration of the MacRath family

A great wave of Irish migration occurred during the 19th century as a direct result of English colonial rule and tight-fisted absentee landlords. Many of these Irish immigrants boarded passenger ships bound for North America. Those who migrated early enough were given land in either British North America or the United States; those who came in the late 19th century were typically employed in industrial centers as laborers. At whatever age they undertook the dangerous passage to North America, those Irish immigrants were essential to the speedy development of the two infant nations to which they arrived, whether they broke and settled land, helped build canals, bridges, and railroads, or produced products for consumer consumption. An examination of immigration and passenger lists has uncovered a large number of immigrants bearing the name MacRath or one of its variants: Bernard, Bridget, Charles, Denis, Edward, Henry, Hugh, James, John, Mark, Michael, Owen, Patrick, Robert, Thomas McGrath all arrived in Philadelphia between 1840 and 1860.
