My Dad's mtDNA haplogroup is I1a1e. This was inherited from his mother, along this maternal line:
Grace Davis < Emily Campbell < Emma MacGregor < Amelia Forbes < Helen Fergusson, who baptised in 1800 in Monteith, Perthshire, Scotland.
On the map below are those nearest matches who have recorded their most distant maternal line ancestor in Europe . These people share a common maternal line ancestor with my Dad. However, that common ancestor likely lived a long time ago. The orange coloured markers have one mutation difference with my Dad's mtDNA, which means that the common ancestor could have lived 400-1000 years ago.
Although I1a1e is considered British, I find it interesting that 2 of the 4 closest European matches are again in Sweden. Did those Scandinavians really get around or did they take a lot of people home with them? Well, they appear to have done both.
Since people of British ancestry have tested their DNA far more than Swedes, of whom it appears only 291 have tested, so we can't necessarily use the predominance of British ancestry to prove a british origin to this particular branch of mtDNA, although it appears likely.
The DNA of my mitochondria, which I inherited from my mother, who inherited it from her mother, etc. is grouped in the haplogroup HV6a.
Davis Simpson < Eileen Simpson < Julia Debreceni < Luyza Daku < Terézia Kaponyás < Juliánna Kovács (b. 1830)
This isn't terribly interesting information in itself. The HV6 haplogroup is largely found found in Iran, Russia, Slovakia and Britain and my maternal line comes from Hungary; Tiszabezded to be precise. Britain is a bit out of the neighbourhood, though, and raises an eyebrow. However, HV6a is a subset of HV6, which means it has thousands of years of its own history. Unfortunately, it appears to be a pretty small group and I can't find much written about it.
What is most interesting is who my mitochondria matches. I have an exact match from a woman from the Ukraine, which, again, is not surprising. I have a few close matches from Hungary, Russia, and Slovakia, which is par for the course. I have 2 from Germany, which isn't too far away. But, then, I have 3 from Sweden, including my second closest match, and 1 from Finland. This is odd.
It's very difficult to fully understand the migration patterns of people hundreds or thousands of years ago but we do know that Swedes did raid and colonize into Russia. They very likely also took back women as slaves. I suspect we'll need a lot more samples to understand how and where our distant maternal lines crossed.
