The Cassidy & Variant Spellings DNA Project is collecting & studying DNA data on Cassidy (and all other possible spellings).  The purpose of these tests is to distinguish the relationships between the various lines.   Most of us realize we have gone as far as possible with traditional methods of research (courthouse records, bible records, etc.). We have lots of theories about how our lines mesh, but we don’t have any proof positive. DNA testing can help solve that problem and could put us on the right track, showing us which lines are related, and which are not. 

Our group is looking for DNA sampling from any Cassidy (all spellings) male, in a direct line of documented descent.  These are the surname spellings that we encourage to participate in our project:

Casety, Casity, Cassaday, Cassady, Cassedy, Cassety, Cassiday, Cassidy,  Cassity, Etc.
