The old Gaelic name used by the O'Brion family in Ireland was Ó Briain, which means descendant of Brian.

Early Origins of the O'Brion family

The surname O'Brion was first found in Thomond, a territory comprised of most of County Clare with adjacent parts of counties Limerick and Tipperary. Prior to the 10th century, the sept was a Dalcassian Clan known as the Ui Toirdealbhaigh and achieved prominence with the rise of their eponymous ancestor, Brian Boru (941-1014), to the High Kingship of Ireland. Brian Boru, by far the most outstanding figure of this family, is widely acknowledged as the greatest of all the ancient Kings of Ireland and is best remembered for driving the Norsemen out of Ireland at the Battle of Clontarf in 1014.

Canada O'Brion migration to Canada +

Under the rule of England, land ownership in Ireland changed dramatically, and many native Irish families found themselves renting out land to farm from absentee owners. This was one of the prime reasons that immigration to North America began in the late 18th century: Irish farmers dreamed of owning their own parcel of land to work for themselves. At this point, the immigrants were at least of modest means for the passage across the Atlantic was often quite dear. In the 1840s the Great Potato Famine created an exodus of people of quite different means. These people were most often destitute: they either sold anything they had to gain a passage or they were sponsored by philanthropic societies. Many of these immigrants were sick from disease and starvation: as a result many did not survive the long transatlantic journey. Although those settlers that did survive were often despised and discriminated against by people already established in these nations, they were critical to rapid development of the powerful industrial nations of the United States and the country that would later become known as Canada. An examination of immigration and passenger lists shows many persons bearing the name of O'Brion or one of its variants:
