Interesting start by Lemminkäinen with the samples he has gathered.

Finns 96 1000genomes
Finns 7 my own collection
Norwegians 15 other sources
Poles 10 other sources
Belarussians 9 Est.BC
Chuvashes 16 Est.BC
Estonians 13 Est.BC
Lithuanians 10 Est.BC
Maris 15 Est.BC
Mordvas 14 Est.BC
Ukrainians 16 Est.BC
Swedes 3 my own collection
Since the last post I have done a lot of testing, I have tried to find limitations of the analysing tool as well as increase my own understanding what all results mean. There is still much work to do, but I am going forward piece by piece and I try to shed light on the Finnish genetic history. In his purpose started my shared LD tests from present-day populations, not from the ancient ones, although it would be more intriguing to resolve big historical questions in our deep past
These results suggest that the Finnish genetic shape is an outcome of several migrations and admixture events, more than I could expect using PCA and formal admixture analyses based on averagely LD-pruned data. The big genetic difference (in Fst-distances) between East and West Finland might be more due to the migration history than genetic drift. Eastern Finnish results show rather young southeastern or eastern admixture history (Mordvas), while western results show older southern admixture (present-day Belarussians). Both groups show also northeastern admixture (Mari->Saami?). It is possible that those three populations are all proxies, most likely this is true in case of Belarussians.
The common history with present Scandinavians is smaller and older than expected, but this doesn’t rule out possible ancient regional migrations from there to Finland. Unfortunately I have not enough samples to check it and regarding Scandinavian migrations to Finland before the Swedish era in Finland my expectations are more focused at ancient genomes. It is worth noticing that I removed all known foreign admixture, including obvious Finland-Swedish samples. It was possible, thanks to my genealogical western Finnish data.
It looks like no particular Estonian migration existed to Finland since the common language diverged and southern migrations to Finland bypassed Estonia.
I am going to find out admixture amounts in following analyses.
