No matter how far upstream rs34276300 turns out to be, R1b1c
haplotypes ancestral for this new marker are a remainder set.
Expecting that remainder set to form a single identifiable geographic
cluster is probably unreasonable.

The spread of R1b1c is already a pretty complex tale, involving
radiation from two refugia, and this new SNP does not appear to
appreciably simplify that tale. At the very least, I anticipate that
the ancestral allele will be present in all R1b1c associated with the
eastern refugia and at least some of the R1b1c associated with the
western refugia. Thus, I'd be very shocked if R1b1c* with
rs34276300- fails to turn up just about everywhere that R1b1c is
currently found.
