McCorkle Surname Y-DNA Project

Testing Process

Join the Project

Once you decide to join, you'll need to have your DNA tested. The company that is providing this service for our project is External link. Click on Join The Project ! at left for more information, or go directly to the online join request External link. (For the 'Type of Test:', select Y-DNA111, Y-DNA67, Y-DNA37, Y-DNA25, or Y-DNA12.)

The Test Kit

After you join, Family Tree DNA will send you a test kit External link. It consists of two cheek scrapers and two collection tubes—designed for a single person's use. You will use the scraper to rub the inside of your cheek, then you'll deposit the tip into the tube. Repeat with the other scraper and tube. The sensation is much like brushing the inside of your cheek with your toothbrush, and is painless.

The Results

Once you've collected the sample, you'll mail the two tubes back to Family Tree DNA, who will perform the Y-DNA test. It usually takes about 4 - 6 weeks to get the results back from the lab. FTDNA will contact you by e-mail when your results are ready. FTDNA will mail you your results, and they will also be available to you online via your secure login. The results (i.e., the marker values) will also be posted on this site on the Test Results page, but rest assured no personally identifying info will be posted.
