Recently received my Full Genomes Yelite results. I am confirmed by Admins(and per preliminary placement on Yfull) to be L1029*, negative for all known downstream mutations. 25 unique SNPs. I only had 3 close matches in FGC. Sadly they were still far. TMRCA between us 2350ypb. The 2 closest matches were from Germany. One(a little further) was a Russian from the Urals. Michal suspects(but uncertain given the instability of the SNP) to form a novel clade upstream of YP263. My placement seems to be at the top of L1029*. My closest match seems to be a Y-SEQ Albanian, TMRCA 1000ypb. I hope to test him(assuming he agrees) to see how the cluster forms between us.
From my understanding each L1029* individual forms their own cluster and have a TMRCA with eachother of 2000ypb. So I may or may not share a SNP with existing Yfull samples that are L1029*. I know its most probable to have arrived with the Avaro-Slavs that invaded Byzantium. However, given the infancy of the science, I feel its too early to make broad conclusions.
From what I see, Basal L1029* like my own seems more widespread than more downstream L1029, which is typical of the migration patterns. Given I lack all the SNPs associated with the migration events from what we currently know, I suspect it could have been Ostrogoths, Bastarnae, Volga Bulgars and even Varangians.
As I understand it, Varangians were hired from Scandinavia to the Baltics and even Russia. Perhaps a Varangian from Kievan Rus carried a more basal L1029* clade to the Balkans. There is also the case as one mentioned earlier, Pomeranian Vikings could well have settled in England and even in the North of France. Perhaps trace ammounts were carried later by Normans, who had a huge impact on Albania, and its tribal customs. They even carried a campaign through my village against the Venetians where they were defeated.
There were also earlier German soldiers stationed in my village, supposedly in 900AD. So it could even be an East German that settled. Even Bastarnae are a possibility. They were still active in the early middle ages, and they expanded throughout east europe before cutting through the East Balkans further west into Macedonia. They could have easily absorbed L1029 in their travels.
I see any number of scenarios. Sadly people are quick to go to tunnel vision and say it only arrived with the great migration Sklavenoi, and not possible other avenues. You have early Antes mercs hired by Rome to fight the Huns that could have carried it. Or even early Slavic farmers prior to the migration that settled in Greece.
Are there any recently published scientific material on M458-L1029? How much do we actually know about it to be certain of who it did or did not come with?
