It's not truly "private" in R1a. Numerous positives have been found.

It is now pretty clear that L176.1 is a "Somerled" SNP: that is, it is likely that
this whole line is L176.1+, most certainly back to the year 1300 and probably
older. It seems to be synonymous to R1a with YCAII = 19,21 and DYS459 = 8,10;
though all L176.1+ cases I am familiar with in addition fit the rest of the Somerled
profile.
