  • Pernille Olsdatter (c.1753 - d.)
    Tilhørte mtDNA haplogruppe T1.
  • Elizabeth Hale (c.1769 - d.)
    DNA Extrapolated mtDNA Haplogroup T, based on test results from a descendant of Eneretta Angell .

The purpose of this project is to document the maternal lineage of all people with the HVR mutations 709, 1888, 4917, 8697, 10463, 13368, 14905, 15607, 15928, 16294. These markers define the mtDNA haplogroup currently designated Haplogroup T.

Defining Mutations

  • Coding mutations 709, 1888, 4917, 8697, 10463, 13368, 14905, 15607, 15928
  • HVR mutation 16294


Haplogroup T is a human mitochondrial DNA (mtDNA) haplogroup. It has an estimated age of c. 10,000 to 12,000 years. In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Tara.

Subclades of T

Famous Members

The last Russian Tsar, Nicholas II, has been shown to be of Haplogroup T, specifically subclade T2.This was established when genetic testing was done on his remains to authenticate his identity. Assuming all relevant pedigrees are correct, this includes all female-line descendants of his female line ancestor Barbara of Celje (1390-1451), wife of Sigismund, Holy Roman Emperor. This includes a great number of European nobles, including George I of Great Britain and Frederick William I of Prussia (through the Electress Sophia of Hanover), Charles I of England, George III of the United Kingdom, George V of the United Kingdom, Charles X Gustav of Sweden, Gustavus Adolphus of Sweden, Maurice of Nassau, Prince of Orange, Olav V of Norway, and George I of Greece. Many European royals have been found to be of this mtDNA Haplogroup, in addition to Haplogroup H (mtDNA).
