I completed a Family Tree DNA test for Y-DNA. My results show I have only six matches. I have viewed the available trees of 4 of the 6 trees, the others are private and unwilling to cooperate. I cannot find any matches but unsure if the Y-DNA is giving me a false positive if that is possible. If I were to compare X-DNA and Y-DNA, would that give me a more accurate rendering of DNA matches? Actually. I am not sure such a comparison is possible.
I am a newbie at using DNA as a resource for finding my ancestral surname family. I am trying to find Farrell family beyond my great grandfather. Any suggestions or corrections to my interpretation of my Y-DNA results.
