O'Carrol History, Family Crest & Coats of Arms
The name O'Carrol has undergone many variations in the time that has passed since its genesis. In Gaelic it appeared as Cearbhaill, which is derived from the name of Cearbhal, the Lord of Ely who helped King Brian Boru lead the Irish to victory over the Danes at the Battle of Clontarf in 1014. Donnchad Ua Cerbaill or Donnchadh Ó Cearbhaill was King of Airgíalla, fl. c. 1130-1168. Maol Ruanaidh Cam Ó Cearbhaill, sometimes Anglicized as Cam O'Kayrwill (died 10 June 1329) was a notable Irish harpist and player of the tiompan who was murdered with many others at the Braganstown Massacre.
Early Origins of the O'Carrol family
The surname O'Carrol was first found in counties Tipperary, Offaly, Monaghan and Louth. Through their connection with Cearbal, they descend from King Oilioll Olum.
There were six distinct O'Carroll septs prior to the Anglo-Norman Conquest. While four disintegrated before the end of the 13th century, the two most important septs continued. These were O'Carroll of Ely O'Carroll, from the counties of Tipperary and Offaly, and O'Carroll of Oriel, from the counties of Monagan and Louth.
While the Oriel O'Carrolls disappeared as an official sept resulting from the Anglo-Norman Conquest, the members of that sept were not scattered, but remained mainly within their ancient territories. However, the O'Carrolls of Ely O'Carroll managed to maintain their independence and heritage until the end of the 16th century, and continued to play an important role in Irish history.
They formerly held large territories in the county of Tipperary, but were confined to the area around Birr in the county of Offaly by the rise of the powerful Norman Butlers.

Migration of the O'Carrol family
Many Irish families boarded ships bound for North America in the middle of 19th century to escape the conditions of poverty and racial discrimination at that time. Although these immigrants often arrived in a destitute state, they went on to make important contributions to the emerging nations of the United States and Canada. An inquiry into many immigration and passenger lists has revealed many early immigrants to North America bearing the O'Carrol family name: John Carroll who settled in Nova Scotia in 1776; Mary Carroll (6 months old) who arrived in Quebec in 1849; Thomas Carroll and his family who arrived in Quebec in 1849.
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: In Fide et in Bello Fortis
Motto Translation: Strong in both faith and war.
