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.
Membership in our Irish 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, and every three years host a rally in County Fermanagh, Northern Ireland where the Cassidys originated. Our next Cassidy Clan rally will take place in Enniskillen, County Fermanagh, in 3-5, July 2020.
We invite you to become a member of the Cassidy Clan. Please visit our Membership Page.
