  • Emily Elizabeth McLain (1885 - 1920)
    Emily's parents were first cousins who never married. There is speculation which of the Rigdon brothers was Emily's father but no details of his identify has been passed down to present-day descendants...

  • Elizabeth Pearson (c.1826 - d.)
    Alternate spelling may have been Grierson, as there were Graysons in the area at the same time who used both spellings. It appears that Elizabeth must have died no later than 1868 because Winlock mar...


Certain subclades of hg H were more prevalent in the Arabian Peninsula (figs. 1 and 3) including H2a1, H4b, H6, and H18, respectively, forming together approximately one half of the Arabian H lineages. Interestingly, H2a1 has been found at a similar high frequency in Central and Inner Asia (12.5%), whereas in Europe, it has been found only in Eastern Slavs (9% from hg H), Estonians (6%), and Slovaks (2%) (Loogväli et al. 2004). H2 forms a quarter of all hg H lineages in Daghestan. Yet, besides H2a1, common in the Arabian Peninsula, other variants of H2, like H2a4, form a large share of hg H in Daghestan. H6 is even more frequent in Central and Inner Asia (21%), especially so in Altaians (35%) (Loogväli et al. 2004).


Phylogeography of Western Eurasian Haplogroups The average frequency of mtDNAs from western Eurasia among northern Asian populations analyzed (with consideration of our previously published data11) is 16.3%. Meanwhile, in the most-western Altaian (Altaians-Kizhi, Teleuts, and Telenghits) and western Sayan (Shors and Khakassians) populations, their frequency is greater (>25%) than that in populations of eastern Sayan (Tuvinians, Todjins, and Tofalars) and, especially, Baikal (Buryats, Khamnigans, Sojots, and eastern Evenks) regions. Western Eurasian contribution to the northern Asian mitochondrial gene pool can be broadly divided into three different components. The first is represented by haplogroups H1a, H1b, H11a, U4, U5a, U5b, U8a, V, T1, and K, which are, in general, characteristic of eastern European populations.56–58 It is likely that these mtDNA lineages were carried to southern Siberia from the Volga-Ural region, where they occur at relatively high frequencies. Some of these maternal lineages are also present at high frequencies in western Siberia (for instance, haplogroups U4, H1b, T1, and U5a).8 The second component comprises haplogroups HV, U3, J1b2, X, H8, and H20, which are typical of populations of western Asia and the Caucasus region.52,53,59 The remaining component, found in southern Siberian populations, is represented by haplogroups H2a1, H6a, J1b1, N1a, and U2e, which are present at relatively low frequencies both in eastern Europe and western Asia. It should be noted, however, that haplogroups H6a and H2a1, as well as H8 and U3, may have been involved in the Late Upper Paleolithic population expansion in the southern Caucasus and the Near East.54,58,59 Therefore, one can suggest that populations from this area had an impact on the mitochondrial gene pool of southern Siberians. In summary, the composition of mtDNA lineages of western Eurasian origin revealed in southern Siberian populations allows us to suggest that there were at least two migrations into southern Siberia, one from eastern Europe and the other from western Asia/the Caucasus. Traces of both migrations associated with different mtDNA haplogroups were detected in all southern Siberian regional groups, with minor influence on the most northeastern of the eastern Sayan populations.



Dr. Mehmet Oz (b. 1960), a Turkish-American cardiothoracic surgeon, author, and television personality hosting the The Dr. Oz Show, belongs to haplogroup H2a1 according to the PBS TV series Faces of America.
