Hi Ed.
According to Geni, I connect with Nial as well.
I might also add my own findings thus far on my DNA:
R1b1a2a1a2a1b1a R-M269 >> R1b-CTS4716 (R1b-Z199, R1b-Z200)
(Morely YDNA subclade predictor) R1b1a1a2 (R-M269; known previously as R1b1a2). R-CTS606.
It seems somewhat similar to yours.
What all this means is relatively unknown to me. However, I do know that (after attending RootsTech last week) the DNA talks indicated that atDNA can only be traced back 6 or 7 generations. Basically, the way the DNA is distributed downstream, much gets lost, dropped off, etc.
I'll throw mud Genesis kit numbers in here as well, if you'd like to run some (unfortunately autosomal checks, as that is all that Gedmatch/Genesis deals with) checks to see if some 'slight' matches come up.
HP9917098 (livingDNA)
PV1099041 (Ancestry)
YD6120745 (FTDNA)
FN5297119 (MyHeritage)
I guess what I'm trying to say is, I don't know how well (how verifiable) all the DNA is with someone so far back as Nial.
Best regards,
Marvin
