The Casey Surname DNA Project

Hi,
My maternal line is Casey, so I am unable to submit a test myself. However, I have 2 male cousins who are Caseys and have had y-chromosome DNA testing done in a different genealogy project.I also know of several other Caseys who were involved in this project. Can they submit their test results to this project? Do they need to test again to be involved in this project? Do they need the approval of the Doctors that sponsored the previous test?
Thank you,
Bernie

Does anyone know when there will be a chart posted which will show comparative results of the DNA project and indicate the earliest known ancestor? Lacking a chart, is there anyone who matches anyone else yet? Given that there are so few participants, can we just reply with who our earliest known ancestor is? (I'm a female represented by my male cousin in the DNA project.) We're descendants of Daniel Casey, b abt 1760, probably in Virginia.) Thanks, Joyce
