O'Bryan History, Family Crest & Coats of Arms
The old Gaelic name used by the O'Bryan family in Ireland was O Briain, which means descendant of Brian.
Early Origins of the O'Bryan family
The surname O'Bryan 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 British first settled the British West Indies around 1604. They made many attempts but failed in some to establish settlements on the Islands including Saint Lucia and Grenada. By 1627 they had managed to establish settlements on St. Kitts (St. Christopher) and Barbados, but by 1641 the Spanish had moved in and destroyed some of these including those at Providence Island. The British continued to expand the settlements including setting the First Federation in the British West Indies by 1674; some of the islands include Barbados, Bermuda, Cayman Island, Turks and Caicos, Jamaica and Belize then known as British Honduras. By the 1960's many of the islands became independent after the West Indies Federation which existed from 1958 to 1962 failed due to internal political conflicts. After this a number of Eastern Caribbean islands formed a free association.

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.
