Only two guys named MAIN have submitted samples so far, and to their SURPRISE they had a perfect match of the basic 12 markers. Neither of us is sure of our ancestry before 1800 although I believe we both are from the Stonington CT MAIN families of the late 1600s and 1700s. What we really need is a man who knows his ancestry traces back to the first Ezekiel MAIN of Stonington Connecticut to submit a sample to compare with. The URL below tells a little more of the study and has an application at the bottom that when sent in will get you a simple test kit to submit your sample. The worst part is that it takes 4 to 6 weeks to get you information back. Considering what I've spent on genealogical travel and annual memberships, I think this is money well spent. Please consider participating in this study if your surname is one of the surname variants. http://www.familytreedna.com/surname_join.asp?code=S43747&special=True&projecttype=S
