I only see ONE Y DNA attached so I am not sure what the letter numbers refer to. From the DNA tab:
DNA propagated to Captain William McFarland
Captain William McFarland is presumed to carry DNA based on test results from other relatives in the family tree:
from 1 relative
Y-DNA (paternal line only)
Private User
from Family Tree DNA
Greater confidence can be obtained by testing other men in the paternal line of Captain William McFarland. View a list of living males who can be tested for Y-DNA to confirm these results.
There are no profiles on Geni with Y-DNA that matches Captain William McFarland.
I am manager of Robert Newton McFarland which I found abandoned and adopted.
He is attached to private Private as son which may be the donor of this Y line.
IS there any action requested?
