Céad Míle Fáilte!

A Hundred Thousand Welcomes!

The Cassidy Clan is a perpetual hereditary association comprised of persons that bear the Cassidy surname or are descended from an ancestor with the Cassidy surname or any of the variant spellings of Cassidy. In the United States, many Cassidy variations exist, including Cassity, Cassaday and Casada.  

Every three years we host a rally in County Fermanagh, Northern Ireland where the Cassidys originated.  The next Cassidy Clan Rally will take place in 2025 from Friday 4 July through Sunday 6 July.


Cassidys studied, prayed, cared for the sick, and taught on Devenish Island for almost 1,000 years.

The Cassidy Clan is a registered clan with the Clans of Ireland.

Membership in the Cassidy Clan is open to all persons without regard to race, ethnic origin, religion, age or gender.  We take great pride in our heritage as physicians, priests, and scholars,  seek to build common bonds among all Cassidys and their descendants.
