First, I see that FTDNA has pushed the updates to the tree for the
Hartley branch. Joel and Michael, your terminal SNP is now recorded as
I just got my YFull results processed and they show me as positive for
A11138 (19477032-A-T). This is an SNP that Joel has, but that Michael
did not test positive for. However, it is right on the edge of a read
area for Michael, so it's quite possible that he also has A11138.
On the other hand, it's right in the middle of a read area for me, so
I would have thought I was negative because FTDNA didn't report it,
but it seems YFull's BAM analysis shows me as positive for it with a 5
If this holds up, then this will make a small A11138 Hartley/Smith SNP
block just below Z17911 and above the Hartley A11132 block. This also
means that Michael has to be positive for this SNP (he can't be
downstream of this block and not have this SNP), which will increase
your shared SNPs by one and decrease Joel's novel variants by one -
effectively moving your shared ancestor closer to present day than
previously estimated by maybe 50-100 years.
I'm going to run all this past Mike W. He can request that FTDNA to a
BAM analysis on this region to see if I and Michael are both A11138.
