First, go to theDavenportDNA project site and read up on the project and the lines. To do that, go here:http://www.davenportdna.com/
From that site, you can go directly to the DNA testing site. Or, you can go here:https://www.familytreedna.com/group-join.aspx?code=P86719&am...
I just did a cusory review of the published Pamunkey literature and I am not sure your line is represented yet. If this is so, WE NEED YOU!
Look forward to seeing you in the project!
