Early Origins of the O'Connell family

The surname O'Connell 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

Canada O'Connell migration to Canada +

Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name O'Connell:
