Etymology of Cains

What does the name Cains mean?

Today's Irish surnames are underpinned by a multitude of rich histories. The name Cains originally appeared in Gaelic as Ó Cathain.

Early Origins of the Cains family

The surname Cains was first found in Derry, where the name literally meant 'Cathan's Son.' "This name may be rendered 'warrior'(cath, 'a battle'). The O'Cathains, now O'Kanes, were of the race of Eoghan, who was son of Niall of the Nine Hostages, Monarch of Ireland, who died A.D. 406." 1

Saint Cainner or Cannera (d. 530?), appears in the martyrology of Tamlacht and other ancient lists of Irish saints on 28 Jan. "According to Colgan, she was born of noble parents in the district of Bentraighe (Bantry) in South Munster. " 2

We would be remiss if we did not mention the English and Welsh origins of the name. In England, Yorkshire was a popular location for the family. The Yorkshire Poll Tax Rolls of 1379 included: Johannes Cayne, Kirkby Overblow; and Johannes Cayne, Knaresborough. 3

"Mauritius de Cadomo held lands in Barony, Devonshire, in 1083. William de Cadomo occurs in Norfolk, Walter de Cadomo in Norfolk, holding great estates, 1086. Renebald de Caen occurs in 1130 (Rot. Pip.). The family of De Caen, Caan, &c., is often mentioned later. In Normandy it occurs in the 12th cent. very frequently." 4

In Wales, "Rhys Cain (16th cent.), was a Welsh poet of the latter part of the sixteenth century, born at Trawsfynydd in Merionethshire, a village on the river Cain, whence he took his surname." 2

Cains migration to the United States +

During the 19th century thousands of impoverished Irish families made the long journey to British North America and the United States. These people were leaving a land that had become beset with poverty, lack of opportunity, and hunger. In North America, they hoped to find land, work, and political and religious freedoms. Although the majority of the immigrants that survived the long sea passage did make these discoveries, it was not without much perseverance and hard work: by the mid-19th century land suitable for agriculture was short supply, especially in British North America, in the east; the work available was generally low paying and physically taxing construction or factory work; and the English stereotypes concerning the Irish, although less frequent and vehement, were, nevertheless, present in the land of freedom, liberty, and equality for all men. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Research into passenger and immigration lists has brought forth evidence of the early members of the Cains family in North America:

By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life.
