The Irish name O'Brean has evolved from the Gaelic Mac Braoin or Ó Braoin.

Early Origins of the O'Brean family

The surname O'Brean was first found in County Kilkenny (Irish: Cill Chainnigh), the former Kingdom of Osraige (Ossory), located in Southeastern Ireland in the province of Leinster, where the family is descended through the Heremon line and claim to be direct descendants of King Niall of the Nine Hostages.

They were known as the Lords of Brawney 1 and were an Ossory sept (Clann) seated near Knocktopher, Kilkenny, until they had to forfeit their lands by the Anglo Norman invasion of Strongbow, Earl of Pembroke in 1172. They were subsequently dispersed throughout Ireland.

Migration of the O'Brean family

Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name O'Brean: Francis Breen, who was on record in Delaware in 1812; John Breene who settled in New York in 1803; Alice Breen, who sailed from Londonderry to Philadelphia in 1847.



The O'Brean 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: Comnac an Ceane
Motto Translation: Fight for Right
