Many variations of the name O'Brennyn have evolved since the time of its initial creation. In Gaelic it appeared as "O Braondin," from the word "braon," which has several meanings, possibly meaning "sorrow" in this case.
Early Origins of the O'Brennyn family
The surname O'Brennyn 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 claim descent from Braonan, an Irish Prince, brother of Ceallach, 17th King of Ossory
. Braonan later became the King of Ossory
, and also King of the Danes of Dublin
, and was known as the Prince of Idough. His son, Conglach, in a dispute over the throne of Ossory, was killed near Three Castles, County Kilkenny
. At this point in time the Brennans were in conflict with Brian Boru (1014), and most historians believe that the family was on the wrong side as allies of the Danish King. After Clontarf, they retained only the principality of Idough, but Anne, daughter of Guidhelgedh, three generations later, married the King of Ossory
(Donogh), and the title was still extant even after the Anglo Norman invasion

Migration of the O'Brennyn family to the New World and Oceana
During the 19th century thousands of impoverished Irish families
made the long journey to British North America and the United States. These people were leaving a land that had become beset with poverty, lack of opportunity, and hunger. In North America, they hoped to find land, work, and political and religious freedoms. Although the majority of the immigrants that survived the long sea passage did make these discoveries, it was not without much perseverance and hard work: by the mid-19th century land suitable for agriculture was short supply, especially in British North America, in the east; the work available was generally low paying and physically taxing construction or factory work; and the English stereotypes concerning the Irish, although less frequent and vehement, were, nevertheless, present in the land of freedom, liberty, and equality for all men. The largest influx of Irish settlers occurred with Great Potato Famine
during the late 1840s. Research into passenger and immigration lists has brought forth evidence of the early members of the O'Brennyn family in North America: James Brennan, a bonded passenger, who arrived in Potomac in 1731;Timothy Branen who settled in Placentia, Newfoundland, in 1744; Laurence Brennan, on record as a laborer in St. John's Newfoundland in 1779.
