I agree with the concern in the Big Thread that we've spent too much time interpreting autosomal DNA-based models, and not enough making judgments based on clear phylogeny (which has gotten much more precise over the last few years). Drawing on a number of sources (JewishDNA.net, YTree, FTDNA's Haplotree, and FTDNA projects), I decided to put together brief, "just the facts" summaries on each of the 10 apparently largest Ashkenazi lineages, all with YFull-estimated TMRCAs between 400 CE and 900 CE. By Wim Penninx's original estimate from a few years ago, these make up about 55% of all Ashkenazi patrilineages.
For the most part I'll leave out my interpretations; I'm interested in yours (and in any blanks you'd be able to fill in). Suffice it to say, some branches have interesting internal structure and some don't; some have a clear link to non-Ashkenazi Jews, and some don't; some have a sibling branch within the historical timescale, and some don't; some appear Levantine, some European, and some unclear in origin.
Might be best to break this up, and post one by one, in descending order of size. Starting with a notorious one:
R1a-Z93-Y2619
Frequency (Penninx): 8.6%
TMRCA (YFull): 700 CE
TMRCA (Behar 2017): 250 CE
Main branches:
R-BY29826 (TMRCA: Not reported)
R-FGC18222 (TMRCA: 850 CE)
- Includes Iraqi Jew (in a downstream clade with Belarusian and Polish Jews with TMRCA: 1725 CE) and Algerian Jew (also in downstream clade)
R-Y2630 (Main branch; TMRCA: 950 CE)
- Includes Turkish Jews (in multiple downstream clades)
Parent branch:
R-CTS6 (TMRCA: 900 BCE)
- Basal individual: Persian from Kerman
- Haplotree identifies possible basal Egyptian, Colombian
- Found in a Scythian from ca. 1050 CE
Sibling branches:
R-Y37891 (TMRCA: 650 CE)
- Includes Persian from Kerman, Iranian Azerbaijani, Iraqi Yazidi
R-CTS7297 (TMRCA: 900 BCE)
- Includes Armenian, Iranian Azerbaijani, Brazilian, and Spaniards
Grandparent branch:
R-F1345 (TMRCA: 1900 BCE)
Uncle branches:
R-YP5484 (TMRCA: 1050 CE)
- Includes Galilee Palestinians (Mamluk tradition?)
R-F2935 (TMRCA: 1700 BCE)
- Includes Black Sea Turk, Balkars, Englishman, Scot, Spaniard, and Ukrainian
