Saint Brendan or Brenainn (490?-573), of Birr, "which was so called from the abundance of wells there (birr, birra, water), now Parsonstown, in the King's County. He was son of Neman, a poet, and Mansenna, and belonged to the race of Corb Aulam, great-grandson of Rudhraighe, from whom were the Clanna Rudhraighe. " 1

Another Saint Brendan or Brenainn (484-577), of Clonfert, was born in 484, at Littus li, or Stagnum li, now Tralee, co. Kerry. "He is termed son of Finnloga, to distinguish him from his contemporary, St. Brendan of Birr. " 1

Early Origins of the Brannan family

The surname Brannan 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 of 1172.

United States Brannan migration to the United States +

Irish families left their homeland in astonishing numbers during the 19th century in search of a better life. Although individual reasons vary, most of these Irish families suffered from extreme poverty, lack of work opportunities, and exorbitant rents in their homeland. Many decided to travel to Australia or North America in the hopes of finding greater opportunities and land. The Irish immigrants that came to North America initially settled on the East Coast, often in major centers such as Boston or New York. But like the many other cultures to settle in North America, the Irish traveled to almost any region they felt held greater promise; as a result, many Irish with gold fever moved all the way out to the Pacific coast. Others before that time left for land along the St. Lawrence River and the Niagara Peninsula, or the Maritimes as United Empire Loyalists, for many Irish did choose to side with the English during the American War of Independence. The earliest wave of Irish migration, however, occurred during the Great Potato Famine of the 1840s. An examination of early immigration and passenger lists has revealed many people bearing the Brannan name:
