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

Early Origins of the O Cean family

The surname O Cean 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

Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States.
