Haplogroups T/L

Haplogroups T is very rare in European populations. Nevertheless, it already has a colorful history

in the DNA genealogy community. Thomas Jefferson reputedly belonged to the T haplogroup, and no less an

authority than Spencer Wells has suggested that he might have been descended from Phoenician traders who visited

pre-Roman Wales. David Faux, on the other hand, believes that T could have been brought to Britain by the Vikings.

T is believed to have originated in Central Asia, and have diffused outward in many directions - perhaps

migrating north to the Baltic, and most definitely moving south to the Middle East. T haplotypes are found

throughout the Mediterranean, and among Jews.

Haplogroup L is also of Central Asiatic origin, and is now found most commonly in India.

T Haplotype #1

The haplotype below is very rare, but both matches suggest an Iberian origin. This haplotype may have been

common among Sephardic Jews, North Africans, Phoenicians, Greeks or other settlers of Iberia during historic times.

It may have come to Britain with Roman troops or settlers, or with Sephardic or Alanic associates of the Normans.

T Haplotype #2

The only match we could find in the YHRD database occurs in Egypt, suggesting that this

haplotype came to Britain with Phoenician traders or other Mediterranean visitors and settlers

prior to or during the Roman era.

T Haplotype #3

This haplotype occurs at very low frequencies in the Philippines and Colombia. The YHRD sample descriptions

do not specify whether or not the samples are of Spanish or mixed descent or entirely aboriginal. The haplotype

may well be Asiatic in origin.

L Haplotype #1

The relevant match here falls in Iran, which suggests that this haplotype came to Britain with an Indo-Iranian group

like the Alans or the Sarmatians.

L Haplotype #2

The only match for the haplotype below falls among the Baloch people of Pakistan. Since the Baloch are Indo-Iranian speakers,

this leads credence to the possibility that this haplotype came to Britain with Alans, Sarmatians or other immigrants of Middle Eastern

or South Asian origin.
