Mitochondrial (mtDNA) Haplogroup T derives from the haplogroup JT, which also gave rise to haplogroup J. Haplogroup T is thought to have originated in Mesopotamia and/or the Fertile Crescent (modern Syria and Turkey) approximately 10,000-12,000 years ago, and then moved northwest in to Europe and east as far as modern Pakistan and India.
In his popular book The Seven Daughters of Eve, Bryan Sykes, who is himself in Haplogroup T, named the originator of this group "Tara," which means rocky hill in Gaelic. Sykes believes that: "Tara herself lived 17,000 years ago in the northwest of Italy among the hills of Tuscany and along the estuary of the river Arno."
The International Society of Genetic Genealogy gives the following standardized description about mtDNA Haplogroup T and two of its main subclades:
"The mitochondrial Haplogroup T is best characterized as a European lineage. With an origin in the Near East greater than 45,000 years ago, the major sub-lineages of Haplogroup T entered Europe around the time of the Neolithic 10,000 years ago. Once in Europe, these sub-lineages underwent a dramatic expansion associated with the arrival of agriculture in Europe. Today, we find Haplogroup T*, the root Haplogroup for Haplogroup T, widely distributed in Europe."
About subclade T1 they write: "The origin of Haplogroup T1 dates to at least 6,000 years ago, and today, we find Haplogroup T1 distributed in populations living in southeast, central, and northwestern Europe."
Regarding subclade T2: "Haplogroup T2 is one of the older sub-lineages and may have been present in Europe as early as the Late Upper Palaeolithic."
Haplogroup T is currently found with high concentrations around the eastern Baltic Sea. According to Oxford Ancestors, Haplogroup T "includes slightly fewer than 10% of modern Europeans. Its many branches are widely distributed throughout southern and western Europe with particularly high concentrations in Ireland and the west of Britain." According to the Genographic Project: "Haplogroup T has a very wide distribution, and is present as far east as the Indus Valley bordering India and Pakistan and as far south as the Arabian peninsula. It is also common in eastern and northern Europe." 
Early agriculturalists and pastoralists
The Genographic Project states that early people with Haplogroup T were likely some of the first organized agriculturalists and pastoralists, and that they probably comprised the group which first brought settled agriculture and pastoralism on to the European continent, bringing the "Neolithic Revolution" to Europe; they write: "Although the haplogroup was present during the early and middle Upper Paleolithic, [Haplogroup] T is generally considered one of the main genetic signatures of the Neolithic expansions. While groups of hunter-gatherers and subsistence fishermen had been occupying much of Eurasia for tens of thousands of years, around ten thousand years ago a group of modern humans living in the Fertile Crescent-present day eastern Turkey and northern Syria-began domesticating the plants, nuts, and seeds they had been collecting. What resulted were the world's first agriculturalists, and this new cultural era is typically referred to as the Neolithic. Groups of individuals able to support larger populations with this reliable food source began migrating out of the Middle East, bringing their new technology with them. By then, humans had already settled much of the surrounding areas, but this new agricultural technology proved too successful to ignore, and the surrounding groups quickly copied these new immigrants. Interesting, DNA data indicate that while these new agriculturalists were incredibly successful at planting their technology in the surrounding groups, they were far less successful at planting their own genetic seed. Agriculture was quickly and widely adopted, but the lineages carried by these Neolithic expansions are found at frequencies seldom greater than 20 percent in Europe, the Middle East, and Central Asia."
