From what I have been able to scrounge from the internet is that H1e is associated with the Hutterites who originated in Austria, Sephardi Jews and has been found in multiple neolithic german individuals.
The earliest direct maternal ancestor that I was able to trace to was a women from around 1860's born in the north western region of the Kingdom of Hanover, now Lower Saxony, Germany. I wonder if it is also prevalent in this region of germany like it was in neolithic times and in Austria and the Hutterites, but I'm also playing with the fact that she could have been partially Sephardi as autosomally I am 4 percent Iberian and I have traced back all my other ancestral lines to at least 1800 with none near the Iberian region.
I did have the pleasure of meeting my great grandmother, the daughter of this woman and from her appearances she seemed like a typical north european and there is no family stories of any ancestry outside that of germany or people with religions outside of protestant from this period, so I am not really sold on the Sephardi ancestry and tend to think that the mtdna was native to the region and that the Iberian dna came from somewhere else.
Does anyone have any info or sources to help me uncover more?
