Etymology of O'Rork

What does the name O'Rork mean?

The Irish name O'Rork has a long Gaelic heritage to its credit. The original Gaelic form of the name O'Rork is Ó Ruairc, which means descendant of Ruairc and; Ruairc is a personal name imported by Norse settlers.

Early Origins of the O'Rork family

The surname O'Rork was first found in counties Cavan and Leitrim (Irish: Liatroim) anciently the western half of the kingdom of Breifne, located in Northeastern Ireland, in Leinster province.

Of note was Tiernan O'Rourke (d. 1172), King of Breifne, called in Irish Tighearnan Ua Ruairc; he was head of the clans known as the Ui Briuin, or as the race of Aedh finn, and ruled Breifne. He first appears in the chronicles in 1124, and at that date had a son, Gillabroide, who was slain in battle with the Connaughtmen. O'Rourke had a considerable body of cavalry, and was defeated by a similar force under Conchobhar MacLochlainn at Ardee, co. Louth, in 1128. In 1130 he defeated and slew Diarmait O'Maelsechlainn, king of Meath, at Slieve Guaire, co. Cavan, and in the following year he ravaged Cuailgne and Omeath, then districts of Ulster, now in the co. Louth. 1

Nineteen other chiefs or tanists named Tiernan O'Rourke occur in the Irish chronicles, of whom the most important was chief of the race of Aedh finn and of Breifne, married Aine, daughter of Tadhg MacDonnchaidh, and died in 1467. 1

O'Rork migration to the United States +

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'Rork or a variant listed above, including:

The O'Rork Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Serviendo guberno
Motto Translation: I govern by serving.
