(I posted this at the R-L21 Yahoo group, but it's worth mentioning here, too.)

The FTDNA haplotree was recently updated to split off Z16423 from the other 13 SNPs that make up the Z255 block:

https://www.familytreedna.com/public/y-dna-haplotree/R;name=R-Z16423

Given that this new R-Z16423 branch is only two SNPs below DF13, this SNP may be of interest to anyone who tested negative for the major DF13 subclades but hasn't done Big Y testing.

I couldn't find this man in the L21 or R1b projects (nor on the Big Tree), and if he's in the Z255 project, his kit is not publicly viewable there, either.

I just saw this thread. Thanks a lot, Swid.

From looking at the BigY block tree of a Z255+ BigY tester in Ireland project I found following interesting titbit:

25 private variants in one BigY test. No details on who the tester is or origin.
