The old Gaelic name used by the O'brion family in Ireland
was O 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
. 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.
