Traditional Research and DNA
The Cassidy Clan supports collaborative, evidence-based genealogy, combining traditional family history research with modern DNA tools to better understand the many Cassidy families worldwide.
Everyone with Cassidy ancestry is welcome to take part.
Build the Shared Cassidy Family Tree
We encourage researchers to add their genealogy to WikiTree , a free, shared, fully collaborative global family tree — designed to be shareable and built on sources and evidence.
Use DNA to Support Your Research
DNA testing can help confirm known lines, distinguish between Cassidy families, and provide clues where records are missing. We support participation in our FamilyTreeDNA and GEDmatch projects.
