I have Garten ancestors and have formed a Garton DNA Project at www.familytreedna.com/public/Garton. Garton was chosen as the lead name because there are more of them but the project includes people with all spellings of the name, including Garten, Gartin, Gorton, Girton, etc.
Please visit the website and read about the project and its goals. I would like to have your suggestions about this website and your feedback.
If you have any quesitons about what DNA testing is or can do for us genealogists, just let me know by responding to this email.
