What does the name O'Roark mean?

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

Early Origins of the O'Roark family

The surname O'Roark 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

Migration of the O'Roark family

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name O'Roark or a variant listed above: Henry Roark who settled in Pennsylvania in 1773; Owen Roarke settled in Philadelphia in 1851; Anne Rourk settled with her husband in Maine in 1822; Bernard, Charles, Daniel, Felix, John, Michael, Patrick, Richard and William Rourke all arrived in Philadelphia between 1840 and 1860.

The O'Roark 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.
