Show ContentsBlaitch History, Family Crest & Coats of Arms

There art two possible origins of the Irish surname Blaitch. The first is that it originated from the Gaelic "O Blathmhaic," which translates as "descendant of Blathmhac," a personal name for the Gaelic "blath" meaning "flower", "blossom", "fame", "prosperity." The second was that the name could have been derived from the Old English word "blaec" meaning "dark" or "swarthy."

Early Origins of the Blaitch family

The surname Blaitch was first found in Connacht (Irish: Connachta, (land of the) descendants of Conn), where the Blake family were one of the Tribes of Galway, descending from Richard Caddell (le Blac), sheriff of Connacht in 1303, who came to Ireland with Prince John in 1185, and used both the surnames Caddell and Blake. 1

The name Caddell is Welsh, and means "warlike." It was not replaced completely by Blake until the 17th century, and for three hundred years, people with these surnames were referred to in municipal records by both names.

"The Blakes of Ireland descend from Richard Blake, who accompanied Prince John to that country in 1185, and settled in co. Galway." 2 Richard Caddle was sheriff of Connaught in 1306 A.D. and was a tenant of Falway under Richard de Burgo (Burke), the Red Earl of Ulster.

Migration of the Blaitch family

Irish families began to immigrate to British North America and the United States in the 18th century, but the greatest influx of Irish immigrants came during the Great Potato Famine of the late 1840s. The earlier settlers came to North America after a great deal of consideration and by paying relatively high fees for their passage. These settlers were primarily drawn by the promise of land. Those later settlers that came during the 1840's were trying to escape the conditions of poverty, starvation, disease, and death that had stricken Ireland. Due to the enormity of their numbers and the late date of their arrival, these immigrants primarily became hired laborers instead of homesteading settlers like their predecessors. An exhaustive search of immigration and passenger lists has revealed many Irish immigrants North America bearing the name Blaitch: William Blake who came from Essex, England, sailed on the "Mary and John" in 1630 and settled in Dorchester, Massachusetts; George Blake settled in Gloucester in 1640.
