I'm gathering here, data on H6a1a, in preparation for my expected FT-DNA mtFull Sequence test results later this month.  23andMe has previously tested me to H6a1.  The James Lick and Wegene analysis services both predict me to be H6a1a8. What will FT-DNA say?

Although this is based on limited samples (albeit rapidly growing samples over the past year), there is of mt haplogroup H spread across Western Eurasia, certainly by the Mesolithic period.  Today, it is the most common haplogroup in Europe, found in 41% of Europeans.

H6 however, is less certain.  It has been suggested that it is more frequent in Eastern Europe, and the Caucasus.  The above ancient DNA references, collected so far, might suggest that H6a1 arrived into Europe with the Yamnaya expansion off of the Eurasian Steppes, carried by Steppe pastoralists migrating westwards, during the Copper Age / Early Bronze Age.  H6a1a itself, first appears in the Corded Ware Culture, which has recently been recognised as a fusion culture, that developed in Eastern / Central Europe, as a result of the arrival of the Steppe pastoralists.

The samples above suggest that H6a1a was present in Britain previous to the Anglo-Saxon period, and was also present in Medieval London.

H6a1a Today

Harvested from the FT-DNA MT-DNA H6 Haplogroup Project (2017-01-02).  These samples are most likely affected by a bias in sampling, to people of European heritage.

H6a1a - T11253C.  Britain, Ireland, Netherlands, Central Europe, Italy, Iberia, Balkans.  A cluster in SW Britain probably caused by sampling bias.

  • H6a1a* - G16526A.  Czech Rep.  Poland.
  • H6a1a* - T3548C.  Sweden, and Sicily.
  • H6a1a2a - C41T, G16482A.  Lithuania
  • H6a1a2a* - A297G, A14970G.  England
  • H6a1a3 - T5785C.  England (Norfolk), Germany, Poland, and Ukraine.
  • H6a1a3* - T7094C.  Finland.
  • H6a1a3a - A827G.  Scotland
  • H6a1a4 - T10237C.  Norway, Poland, England, and Ukraine.
  • H6a1a5 - C10936T.  Very Eastern Europe - Russia, Belarus, Ukraine, Moldovia, and Romania.
  • H6a1a5* - T5302C.  Russia.
  • H6a1a6 - A288G.  Poland.

2017-01-04 UPDATE


I received my FT-DNA mtDNA Full Sequence test results.

Confirmed H6a1a8.


Matches mainly North America and Australasia without many Old World provenances.  However, I'm getting the distinct impression that it's been in the British Isles for some time.  I'm starting to research, but I'm seeing England, Ireland, Wales, maybe Finland.

Using the above Behar et al dating of H6a1a8, I age this haplotype to between 1970 BC and 1825 AD.  It's not old, although most likely late prehistoric.  It must have formed after Corded Ware, Unetice, etc.  Might date towards the end of the Bell Beaker Culture at a stretch, but most likely later - Iron Age perhaps?

My main interest is origins, with genealogy only as a bonus. I'm interested in knowing where H6a1a8 originates! H6a1 has been found in Yamna context. H6a1 and H6a1a have been found in Corded Ware context. No earlier H6a1 found in European atDNA. So it appears likely, that H6a1/a was an mt DNA type that followed the many Y-DNA types of the Copper Age Steppe migration across Europe - despite the usual dominance of Steppe Y haplogroups in Western Europe that indicate a male sex bias. 

Behar et al., 2012b, dates H6a1 to 8,669.7 ± 1,905.2; CI=95%, H6a1a to 7,139.5 ± 1,993.2; CI=95%, and H6a1a8 to 2,023.7 ± 1,898.9; CI=95% So I see H6a1a8 as pretty young, most likely Bronze Age or Iron Age. I'm curious as to when it distributed through Europe, and when it likely entered the British Isles. My mt-line has been in Norfolk, England for at least 290 years, when my earliest mt ancestor, Susannah Briting was born. She married my ancestor at Bunwell, Norfolk in 1747. I'd say that the probability is that it had been here in East Anglia long before that paper trail. So when did it likely move here?

23andMe had previously tested me to H6a1. Both the James Lick mthap analyser, and WeGene, looking at the 23andMe raw data, took that to H6a1a8. They were correct:

The FT-DNA mtFull Sequence confirmed my mt haplogroup to be H6a1a8.

My HRV1 mutations are: A16129G, T16187C, C16189T, T16223C, G16230A, T16278C, T16298C, C16311T, T16362C, A16482G, C16519T
My HRV2 mutations are: G73A, C146T, C152T, C195T, T239C, A247G, 522.1A, 522.2C, 309.1C, 309.2C, 315.1C
Extra mutations are: 309.1C309.2C315.1C522.1A522.2CC16519T

HRV1 matches are:

England 3
Hungary 1
Ireland 4
UK 1
USA 1

HRV1 + 2 matches are:

England 2
Hungary 1
Ireland 3

I have a "HRV1, HRV2, and Coding Region" exact match: Ireland 2

On Matches I get four GD0, but all appear USA/Aus, etc. I have emailed them. Three replied. No paper or geographical correlations. They can't follow their mt lines previous to emigration. They could come from anywhere in Europe, although English surnames keep dominating on their maternal sides.

On Matches map, a little more hope:



I've joined the H6 project, but being a development of the pretty massive mt hg H Project, it is drowned in submissions, with a long waiting queue of "ungrouped". The only other H6a1a8 on the results is USA. There is a H6a1a8a ungrouped as private located as "Finland", and another H6a1a8a located to Wales.

I have recently received my DNA and I have the H6a1 gene. I am new to all of this so I have alot to learn.
