Thank you for the suggestions. In case I didn't make it clear, this man has already tested at FTDNA but did not join our project for some reason. I plan to mention discounts on further testing, but he has already tested 37 markers. I'll mention the support of a project administrator and the simplicity of joining. Also if he will tell me about his earliest paternal ancestor, I can compare that information with other project members, and introduce him to any who have a common ancestor or at least ancestors in the same locations. This is an improvement over writing to several matches about whom he knows nothing except their surnames and Y-DNA. Carol B.
