Thanks Darrel. I noticed your post from a couple of years ago, and luckily I have more context recently as I have done a bit of a deep dive into the issues you raise. Lots to talk about.
We have this forum but I've also set up a smaller space to discuss L193 haplogroup issues - including origins, matching, history, geography, testing plans, etc.
For now let me copy here the latest version of the tools I use to put these pieces together more. One is a timeline that you may have seen before, in an earlier form. The other is a synthesis of what is knowable about some of these issues that relies on formal sources. It's not a treatise, just an attempt at summary of what is known or not presently in the record.
I'm guessing that there is still incredible detail in-between the broad strokes these tools present, but my hope is that they can be foundational for every genetic cluster and surname family lines by extension with their own findings (for instance). Let me know your thoughts.
