About us
Cassidy - Ó Cassidy - Ó Caiside is an ancient Irish name. There are many Cassidy variations, including Cassity, Cassaday, Cassedy and Casada - our project is open to Cassidy's and all spelling variations of the name.
* To determine possible relationships between other CASSIDY lines of Irish descent (including those in the British Isles and other countries).
* To assist CASSIDYS not sure of their lineage to determine which of these broad groups they might fit into and to be able to collaborate with others.
* To identify at least two male CASSIDY's from each documented CASSIDY line of descent to undertake Y-DNA testing, preferably at the Big-Y level.
