Haplogroup T - European Genealogy

If you're doing DNA testing for genealogy, you probably have encountered Haplogroup T. In mtDNA testing, this is the huge european group of people. When you compare the HVR-1 region of the mtDNA against the standard of the Cambridge Reference Sequence, people are categorized as haplogroup T if they have these mutations:


I indeed had these two mutations in my ancestry, meaning my ancestry was a haplogroup T!

Professor Sykes developed "fancy names" for each of the 7 haplogroups of Europe instead of just calling them T and Z and so on. Since these are traced on the maternal line, he invented a "female clan leader" for each group that apparently spawned the entire clan.

The haplogroup T clan is called the "Tara" clan, which is Gaelic for "rock". This is the group that began in Italy and then migrated across europe into England and Ireland.

In addition to this "base clan" mutation, I had two other mutations:


The 16519 spot is considered "volatile" - i.e. it often randomly changes without much meaning. So it's not an indicator of anything. The 16296T also does not seem to be a primary indicator of location.

So a warm hello to all fellow "Tara Clan Members" out there - and if you have the other two mutations in your DNA, be sure to write me!
