Show ContentsBlaech History, Family Crest & Coats of Arms

There art two possible origins of the Irish surname Blaech. 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 Blaech family

The surname Blaech 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 Blaech family

In the 18th and 19th centuries, thousands of Irish families fled an Ireland that was forcibly held through by England through its imperialistic policies. A large portion of these families crossed the Atlantic to the shores of North America. The fate of these families depended on when they immigrated and the political allegiances they showed after they arrived. Settlers that arrived before the American War of Independence may have moved north to Canada at the war's conclusion as United Empire Loyalists. Such Loyalists were granted land along the St. Lawrence River and the Niagara Peninsula. Those that fought for the revolution occasionally gained the land that the fleeing Loyalist vacated. After this period, free land and an agrarian lifestyle were not so easy to come by in the East. So when seemingly innumerable Irish immigrants arrived during the Great Potato Famine of the late 1840s, free land for all was out of the question. These settlers were instead put to work building railroads, coal mines, bridges, and canals. Whenever they came, Irish settlers made an inestimable contribution to the building of the New World. Early North American immigration records have revealed a number of people bearing the Irish name Blaech or a variant listed above, including: 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.
