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

The surname Bleech 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 Bleech family

The 18th century saw the slow yet steady emigration of Irish families to British North America and the United States. Those early Irish settlers that left their homeland were typically moderately well off: they were enticed by the promise of a sizable plot of land. However, by the 1840s, this pattern of immigration was gone: immigrants to North America were seeking refuge from the starvation and disease that the Great Potato Famine of that decade brought. The great numbers of Irish that arrived to the United States and the soon to be Canada were instrumental in their quick development as powerful industrial nations. An examination of early immigration and passenger lists uncovered many early immigrants bearing the name Bleech: 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.
