O'Brian History, Family Crest & Coats of Arms
- Origins Available:
The old Gaelic name used by the O'Brian family in Ireland was O Briain, which means descendant of Brian.
Early Origins of the O'Brian family
The surname O'Brian 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.

O'Brian migration to the United States +
Irish immigrants began to leave the English-controlled Ireland in sizable numbers during the late 18th century. Many of these Irish immigrated to British North America or the United States in the hopes of gaining their own tract of farmland. This pattern of migration grew steadily until the 1840s when the Great Potato Famine caused a great exodus of immigrants to North America. These immigrants differed from their predecessors in that they were desperately fleeing the disease and starvation that plagued their homeland, and many were entirely destitute when they arrived in North America. Although these penniless immigrants were not warmly welcomed when they arrived, they were critical to the rapid development of the United States and what would become known as Canada. Many went to populate the western frontiers and others provided the cheap labor the new manufacturing sector and the building of bridges, roads, railways, and canals required. A thorough examination of immigration and passenger lists has revealed some of the earliest people to arrive in North America with name O'Brian or one of its variants:

The O'Brian 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: Lamh laidir an Uachtar
Motto Translation: The strong hand from above.
