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 Brendan family

The surname Brendan 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.

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.
