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

Early Origins of the Briens family

The surname Briens 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.

The Briens 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.
