On the ethnolinguistic origin of the Meshchera, Pauli Rahkonen had an interesting proposal that might eventually be tested with Bronze Age and Iron Age DNA samples from North-East Europe: The Linguistic Background of the Ancient Meshchera Tribe and Principal Areas of Settlement, FUF (2009) 60:160-200.
NOTE. The paper is included in his PhD Dissertation, South-eastern contact area of Finnic languages in the light of onomastics (2013).

Open access Siberian genetic diversity reveals complex origins of the Samoyedic-speaking populations, by Karafet et al. Am J Hum Biol (2018) e23194.
Interesting excerpts (emphasis mine):
Consistent with their origin, Mongolic-speaking Buryats demonstrate genetic similarity with Mongols, and Turkic-speaking Altai-Kizhi and Teleuts are drawn close to CAS groups. The Tungusic-speaking Evenks collected in central and eastern Siberia cluster together and overlap with Yukagirs. Dolgans are widely scattered in the plot, justifying their recent origin from one Evenk clan, Yakuts, and Russian peasants in the 18th century (Popov, 1964). Uralic-speaking populations comprise a very wide cluster with Komi
