Irish surnames are all based on the Gaelic language native to Ireland. The original Gaelic form of the name O'Conils is Ó Conaill. 1

Early Origins of the O'Conils family

The surname O'Conils was first found in County Limerick where O'Connell was the chief of Hy-Cuilean, a territory south-east of Abbeyfeale, in the barony of Upper Connello near the borders of Cork and Kerry. The O'Connells had their chief residence in Castle Connell. In the twelfth century the O'Connells settled in Kerry. One reference claims that the O'Falvies, admirals of Desmond; the O'Connells, of Kerry; O'Sheas, chiefs of Muskerry, in Cork; and several other chiefs, claim descent from the Clan na Deaga, Chiefs of Munster, originally a branch of the Heremonians of Ulster.

The Cannell variant is "a name peculiar to the Isle of Man, is from the Celtic MacConaill." 2

Migration of the O'Conils family

The 19th century saw a great wave of Irish families leaving Ireland for the distant shores of North America and Australia. These families often left their homeland hungry, penniless, and destitute due to the policies of England. Those Irish immigrants that survived the long sea passage initially settled on the eastern seaboard of the continent. Some, however, moved north to a then infant Canada as United Empire Loyalists after ironically serving with the English in the American War of Independence. Others that remained in America later joined the westward migration in search of land. The greatest influx of Irish immigrants, though, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America, and those who arrived were immediately put to work building railroads, coal mines, bridges, and canals. In fact, the foundations of today's powerful nations of the United States and Canada were to a larger degree built by the Irish. Archival documents indicate that members of the O'Conils family relocated to North American shores quite early: John Cannell who settled in Boston Massachusetts in 1652; John Cannell settled in New England in 1652; Henry Cannell settled in Philadelphia, Pennsylvania in 1852.



The O'Conils Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Ciall agus neart
Motto Translation: Reason and power.
