Jewish Y-DNA branch AB-040

Introduction

This group has been studied several times. A nice collection can be found in Wirth ftdna site. The distribution in the diagram below suggests a Middle East-Sephardic line.

On the origin on CTS2906: as indicated on http://tree.j2-m172.info/?Hg=J2a1a1b1a1 four lines are known below CTS2906. One is from the Sardinian paper (Francalacci et al.), one from Toscane from the 1kG project, One has not reported an origin (311816), and one is the Ashkenazi branch. The length is on average 45 FGC markers, so about 4000 ybp. In the ftdna project we have a person from the Netherlands and one from Italy. Where and when a person became Jewish is unknown. Two markers were shared between the Ashkenazi branch and the person from unreported origin. Since the BAM files of the other two branches are not analysed for these markers, we do not know if they share the same markers. Near CTS2906 several branches were found in the Toscani region from the 1kG and Sardinian project. It is more likely that this group increased in size in Italy or neighboring area after the shared ancestor lived there, than that the individuals arrived as a group from one location a thousand years later to this area.

In the ftdna project site Jewish DNA we can find E11451 (Marquez) and 271540 (Turkey) at a distance of about 1000 years, suggesting that some members left Iberia after the Inquisition. This is a very small percentage.

Genealogical study: A study by the Bacharach family (from Frankfurt DNA project) is found on http://bacharachdna.com/. In the beginning of the 16th century four German cities had many Jews: Prague was the largest, followed by Vienna, Frankfurt and Worms.
On the Jews of Frankfurt website a very nice Y-DNA STR familytree is shown which follows the historic information of the movements of the family members.

On the 2013 IAJGS Conference on Jewish Genealogy in Boston a presentation and paper was presented on the genealogical data and Y-DNA analysis of this branch. Many of the familynames in the first period in Germany followed the names of the cities: Bacharach and Treves in the Rhein-Frankfurt region, and later Fürth, Wertheim, Weil (see also Weil surname), and Fürth in the direction of Bavaria. The Jewish history of these cities in these periods (1000-1300 CE) is well known. The origin of other names like Schwab could be related, but is more uncertain.

On the STR and SNP variability in this Ashkenazi branch: this branch has several STR characteristics that are grouped. We can compare the subranches of Treves-Weill with Bacharach-Wertheimer, because of the Wirth project diagram. The Bacharach branch has DYS464=13-13-16-16-16-16 (Treves: 13-13-15-16-16-16), DYS557=14 (Treves: 15), DYS446=often 14 (Treves: 13), DYS505=13 (Treves: 14), DYS549=12 (Treves: 13), DYS463=22 (Treves: 21). This suggests that males were 6 mutations took place between Bacharach-Wertheimer and Treves-Weill. If we determine the tmrca of the two ancestors, they are 1240 and 1150. This means that we have two scenarios, which can be checked with next generation SNP analysis: the two are parallel relatives, or MRCA of the first groups is a descendant of the MRCA of the second group; in this case the first ancestor had a somewhat larger population growth than the second. Because of the similar tmrca of both groups, it seems more likely that they were parallel. The shared ancestor would be a little earlier, like 1000 ybp.
