Thank you for your super quick response! And, I think I get what you are saying, kinda, and I suppose my confusion is that the two kits in question belong to siblings and that although they both match my father, they don’t match him in the same manner/via the same DNA…correct? Heavens, I sound like a complete amateur!
And, when you say NPE, is the fact that my father might be that NPE what could be causing this? He is the adoptee and the two sibs (Mar and Ross) would be my father’s 2C (I think that’s right).
Also, I don’t see any Genesis kits in the in the original cluster. Maybe I’m just being dense, but I know that Ross triangulates with my father and other kits in that cluster, the one that includes Mar. There are several family members of theirs that have tested. I guess I am at a loss and with my frustration, just not doing a very good job or verbalizing what it is that I am seeing.
