Sweeney / Family History

The names Sweeney and McSweeney in Ireland are derived from a number of Gallowglass Septs called McSuichne that were established in the country in the fifteenth century. The name is now most commonly found in the Province of Munster and in County Cork in particular where the majority of descendants can be found.

A Sept is an ancient Clan-like collective describing a group of persons whose immediate ancestors bore a common surname and inhabited the same territory.
