(A) FineSTRUCTURE results with two populations that we labeled west (W) and east (E). (B) Results from A refined by marking with yellow circles the individuals whose assignment is uncertain (<80% assignment probability to both populations). Also shown are the approximate 1323 borderline of the treaty of Nöteborg, the early vs. late-settlement border from Figure 1, and the regions of E and W dialects of the Finnish language, including partly Swedish-speaking coastal regions.
