Origin of the Long Clan Name

The Irish Longs may have got their name from different origins, English, Scottish and Norman descent. A number of Irish Gaelic septs of O'Longain and O'Longaig contributed to the origin of this surname. One sept was located in County Armagh, but the greater numbers were in County Cork at Cannovee and also at Moviddy.

This  surname may also belong to that group of names which originate from a nickname attributed because of some characteristic. In this case it stems from the nickname origin, meaning being tall, lanky or long.

Norman settlers suh as de Long in the 12th century may also be the originators of some Long families.
