O'Tierney History, Family Crest & Coats of Arms



Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Tierney originally appeared in Gaelic as O Tighearnaigh, which is derived from "tighearna," which means "lord."

Early Origins of the O'Tierney family


The surname O'Tierney was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where their chiefs were the Lords of Carra. Over time, the name became scattered through Ireland, but pockets of the name can still be found in most counties of Mayo and Connacht.

Migration of the O'Tierney family to the New World and Oceana


To escape the religious and political discrimination they experienced primarily at the hands of the English, thousands of Irish left their homeland in the 19th century. These migrants typically settled in communities throughout the East Coast of North America, but also joined the wagon trains moving out to the Midwest. Ironically, when the American War of Independence began, many Irish settlers took the side of England, and at the war's conclusion moved north to Canada. These United Empire Loyalists, were granted land along the St. Lawrence River and the Niagara Peninsula. Other Irish immigrants settled in Newfoundland, the Ottawa Valley, New Brunswick and Nova Scotia. The greatest influx of Irish immigrants, however, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America and Australia. Many of those numbers, however, did not live through the long sea passage. These Irish settlers to North America were immediately put to work building railroads, coal mines, bridges, and canals. Irish settlers made an inestimable contribution to the building of the New World. Early North American immigration records have revealed a number of people bearing the Irish name O'Tierney or a variant listed above, including: John Tiernay arrived in San Francisco in 1851; Bernard Tierney settled in Philadelphia in 1852 and 1880; James Tierney settled in Philadelphia in 1855.
