That's unfortunate. So if I am a male Lewis surname descendant and I've had my DNA tested elsewhere other than Family Tree DNA, I can't come to your party? What is the ethical and scientific justification for such a restriction? NOTE: I'm not suggesting a conflict of interest. I know that LJ Crain is a sincere and dedicated genealogy researcher, and I appreciate everything she's done to promote and sustain this project. It just seems suggestive at best, and counterproductive in the long run, if the true goal of this project is to research DNA connections, to limit one's participation to one DNA testing lab.
