I'm currently in a surname project run through Family Tree DNA and I have a feeling the posted results of this project are completely wrong. it seems that the people running the project might have an agenda which is dictating how they are posting the results. For example, they have me in a group with 7 other people. 3 of these are actual DNA matches or close matches, the other 4 have genetic differences with me of between 9 and 17. One of the project managers claim they are 100% sure that all 8 of us share the same ancestor from approx the year 1400. I'm not buying it. Can anyone here shed some light onto this?? A link to the project DNA results is below. Any help would be greatly appreciated!!
