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

The surname Blaack 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 Blaack family

Ireland saw an enormous decrease in its population in the 19th century due to immigration and death. This pattern of immigration began slowly in the late 18th century and gradually grew throughout the early portion of the 19th century. However, a dramatic increase in the country's immigration numbers occurred when the Great Potato Famine struck in the 1840s. The early immigrants to North America were primarily destined to be farmers tending to their own plot of land, those that came later initially settled within pre-established urban centers. These urban immigrants provided the cheap labor that the fast developing United States and soon to be Canada required. Regardless of their new lifestyle in North America, the Irish immigrants to the United States and Canada made invaluable contributions to their newly adopted societies. An investigation of immigrant and passenger lists revealed many Blaacks: 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.
