I have been looking for a link to the tree names above that included some estimates of timeframes that they split off but just cannot seem to find that link. Can someone help point me in the right direct? TY

Here is another version of the tree that's more complete, in several ways -- although Alex Williamson's partial sample is not identical with YFull's partial sample. For instance, the caption says:
These are the NGS tested men in group R-DF27/S250

But they are only the ones Alex can see. For example, under the SNP S1217/Z295, way off at the right end is one guy, Winters (who posts here, btw) who is NextGen tested, and negative for the two large divisions represented by CTS4065 and Z216. As an admin of the DF27 project, I can see four more; Alex doesn't see them because they have not yet uploaded their BigY .bed file to the Yahoo group, or made their FGC analysis similarly available (if that's where they were sequenced). Only two of these five Z295* guys appear to share any novel variants; so there might be four or more subclades of Z295 that we have yet to place on the tree, at the same level as CTS4065 and Z216. Or at a minimum one more subclade, with four mutually exclusive descendant branches.
