  • Iberia South, 17 STR, ? SNPs, 416 samples, surname clusters: Calderón et al 2015, “three surname cases with 3 occurrences each carrying haplogroups E-M81, I1-M253, and J2-M172 respectively. […] the J2-M172 seems to be related to Greek and Phoenicians colonies that were well established at least from the first millennium BC in the Peninsula, particularly in littoral Andalusia […] toponymic surname “vc” refers to a northern Andalusian town with a castle […] defended by Muslim garrisons in the 12th century. In this survey we have found three carriers of this surname with family origins in Granada territory (300 km far away from that town). The three Y-C harbored the J2a1 haplogroup with two of them sharing indeed 17 loci Y-STRs haplotype. These results suggest that the sampled “vc” males would be descendants of a member of that Muslim garrison, revealing then a clarifying case of Arab ancestry.

PF5197) and also J2a-M68, a lot of J2b-M241 and some J2b-M205; J2a-M410 mainly NW border (Gujarat, Rajasthan, etc.; 17–50% in Toda, Chenchu, Banjara, Kamboj, Lohana, Kashmiri Muslims etc); J2b2-M241 concentrated in Eastern India (15–35% in Asur, Narikuravar, Pichakuntla, Shikari and Mondi, etc.).
  • Nepal/India, 12 STRs, ca. 40 samples: Fornarino et al 2009, “haplogroup J (Tharus 14.0%, Indians 5.8%), present only as J2, namely J2-M410* and J2-M241*. Whereas the latter haplogroup is shared by all Indian and Tharu samples, the J2-M410* was found in all Tharus but in only one Hindu of New Delhi, where one sample of its derivative J2-M68 was also present. If one considers the total frequency of this component in each sub-group, among Indians the highest value is observed in the Hindus of New Delhi (10%), and, among Tharus, in the group of Eastern Terai (30%)
