We are dedicated to using Y-DNA results to sort-out the different family groups that stem from Cawley, Cauley and Colley.  Individuals with different spellings may descend from a common ancestor in the not-so-distant past, and not even know they are related. It is our goal to help them connect.

Some of the known spellings are Caulley, Cauley, Cawley, Colley, Collie, Colie, Cowley, Calley, Cally, Cauly, Colly, Cowly, Corley.  If you know of any others that should be included, please email Tom Caulley.
