Actual and Predicted SNP-Based Clusters for R1a-Y2619 Ashkenazi Levites

The following table identifies the R1a-Y2619 Ashkenazi Levites who have tested to at least 37 markers as of July 3, 2021, followed by their haplogroup as identified by FTDNA, their Big Y status, their cluster (Y2630, FGC18222, or Y2619* (including BY29826)), and their subcluster.

For men who have had their cluster or subcluster identified through full or a la carte Y-DNA testing (through FTDNA's Big Y test or a la carte Y-DNA SNP testing, Full Genomes Corp.'s Y-DNA testing, or YSEQ's a la carte SNP testing), the clusters and subclusters are identified with no notation.

The two tables below (the first is sorted by kit number, and the second is sorted by cluster) identify predicted clusters and subclusters (the notation "[P]" is used to designate men whose clusters and subclusters are predicted, rather than based upon SNP testing). Those predictions are based on patterns of STR marker values. Because one of the key predictive STR marker is located on markers 68 through 111 while the second key predictive STR marker is located on markers 38 through 67, it is sometimes difficult to predict clusters (and typically difficult to predict subclusters) for men who have tested to only 37 markers.

Kit numbers with the prefix "ZZZ" are kits for which I do not have kit numbers.

This website also posts: (1) the key STR marker values and star trees for the R1a-Y2619 Ashkenazi Levites who are predicted to be R1a-Y2630; (2) the key STR marker values and star trees for the R1a-Y2619 Ashkenazi Levites who are predicted to be R1a-FGC18222; and (3) the key STR marker values and star trees for the R1a-Y2619 Ashkenazi Levites who are predicted to be R1a-Y2619* (including R1a-BY29826 and R1a-BY73299) (i.e., neither R1a-Y2630 nor R1a-FGC18222).

Predictions as to clusters and subclusters for men who have not done full Y-DNA testing are based largely upon a comparison of their pattern of STR marker values to those of men who have done such testing. To make it easier to identify the pattern of STR marker values that may be characteristic of particular clusters or subclusters, this website posts the key STR marker values for R1a-Y2619 Ashkenazi Levites who have done full Y-DNA testing, sorted into subclusters.

Two markers - DYS537 and DYS650 - have the greatest predictive value for clustering R1a-Y2619 Ashkenazi Levites as Y2630+, FGC18222+, and Y2619*. As a general matter, men who have DYS537=12 and DYS650=20 are likely to be R1a-Y2630, men who have DYS537=11 and DYS650<20 are likely to be R1a-FGC18222, and men who have DYS537=12 and DYS650<20 are likely to be R1a-Y2619* (including R1a-BY29826 and R1a-BY73299). (Because of back mutations and independent mutations, however, there are a significant number of men who do not fit this rule.)

Without full Y-DNA testing, it is often difficult to identify subclusters for men who are R1a-Y2630. There are a few exceptions to this rule; for example, the marker value DYS495=16 is characteristic of the R1a-YP268 subcluster of R1a-Y2630.
