IHDP Haplogroup J - Members Results Table

Haplogroup J is subdivided into two haplogroups, haplogroup J2, defined by the M172 marker and haplogroup J1, defined by the M267 marker. Haplogroup J is believed to have arisen between 10,000 and 15,000 years ago in the Near East. It is most closely related to Haplogroup I, as both Haplogroup I and Haplogroup J are descendants of Haplogroup IJ (S2, S22). Haplogroup IJ is in turn derived from Haplogroup F.

IHDP J2 and J1 Members Results

Most J IHDP members are found to have Haplogroup J2 about 80% about 20% are J1. There is no consistent pattern to its distribution in Ireland nor among surnames.

J2 Distribution: Haplogroup J2 is present especially in the Levant and Anatolia (Turkey). Found in the Sephardim Jews (28,6%), Muslim Kurds (28,4%), Central Turks (27,9%), Georgians (26,7%), Lebanese (25%) and Ashkenazim Jews (23,2%). It is also very frequent in the Balkans (Greeks 20,6%, Albanians 19,6%) and in southern Italy (16,7-29,1%). Its frequency rapidly drops in the Carpathian basin (Croatians 6,2%, Hungarians 2,0%, Ukrainians 7,3%). The significant presence of J2 (J2b2+J2a) in India (18,6% in Dravidian upper castes, 14% in Aryan upper castes, 2% in tribes; Sengupta et al. 2006) must be of a very early date, because Indian J2 is not accompanied by E3b1, that must have penetrated to the Near East from North Africa after the end of the Ice Age. E1b1 is tightly bound with the spread of both J-subbranches since the neolithic era.

J1 Distribution: Haplogroup J1 appears at high frequencies among populations of the Middle East, North Africa, and Ethiopia (Thomas et al. 1999). J1 was spread by two temporally distinct migratory episodes, the most recent one probably associated with the diffusion of Muslims from Arabia since the 6th century CE.

Historical Note: The Cohen Modal Haplotype falls in haplogroup J1, with respect to Cohens. (But the same CMH marker can sometimes be found in other haplogroups too, like J2). The bulk of CMH is observed in J1 (53,0%) and J2 (43,2%) with a small portion falling outside haplogroup J (3,8%). Although you can have the CMH in either J1 or J2, it is the genetic signature in J1 that is considered the Jewish priestly signature.

I.H.D.P Listing of the J2 and J1 Haplogroup Members Results Presentation

Here is the complete set of IHDP J group membership results. In the Excell file there is an autofilter on the header to enable turning/on/off columns and carrying out queries. A CSV file can generated by Excell, simply by Saving it in a CSV format and can then be used for further research.

In the results table below, Red Columns indicate Fast Mutating DYS Markers, these can and should be used to determine relatedness between close matching results. The Blue columns reflect the ten markers used in the appendices of Bryan Sykes book "Blood of the Isles" - Bantam press, London. The results associated with the book are available as a downloadable PDF file from the following website: Blood of the Isles. The Blue Columns can be used for studying deep ancestry.
