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

Early Origins of the O'Rorke family

The surname O'Rorke 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
