1. How are you, the McCorkle Study administrator, going to protect my privacy?

Please see the Privacy FAQ page. Personally identifiable information is never presented on this site unless expressly requested by the participant.

2. How do I contact another participant on this site?

Send me an email with the Kit number of the participant you wish to contact (select “Email” in the Menu at left). I will forward your email address to that participant, who then has an option of replying to your request or not. Ideally, everyone will reply, but it is possible that the donor may want to maintain their privacy.

3. I have relatives who may want to join this project. What should I do?

Send your relative's name and email address to the administrator. Just remember that the potential donor must be a living male McCorkle descendant. If you prefer, you may sign up for a collection kit to be sent directly from FamilyTreeDNA.com .

4. Is there more information about DNA on the Internet?

Yes, quite a bit. Just enter “genealogy dna” or “genetic genealogy” in your favorite search engine.

5. Why is it that you insist on male members of the McCorkle clans?

The Y chromosome of a man's DNA is passed unaltered from himself to his son. Also, in western cultures, the surname is also passed from father to son (children don't usually take their mother's surname). Therefore, by comparing DNA of two individuals with the same surname, it can be determined whether or not they are related. If there is a close DNA match, then the two men probably share an ancester within the timeframe of surname use (typically, over the past 500-800 years), which could be corroborated using traditional genealogical research.

6. Do the DYS markers contain personal information related to a person's health or inheritance of disease-related genes?

No. A small strand of the Y chromosome is tested, but the portions (markers) used are inoccuous "junk" strands.

7. If my DNA Kit page (linked from the Test Results page) has an error or omission regarding my ancestors' names, dates, or migration pattern, can it be corrected?

Please send the Project Administrator an email with the correct information.

8. If participants from the same genealogical lineage have entirely different DYS marker patterns, what could be the cause?

It could be that a McCorkle ancestor adopted a boy from outside the family. Other causes would involve "non-paternity issues" (infidelity, step-children, etc.) And lastly, the subject participants may not actually belong in the same line because of errors in family traditions or family records.
