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).

The ethnonym Meshchera [Мещёра] is not found in such very early Russian chronicles as Povest’ vremennyh let [“Nestor’s Chronicle”] (PSRL 1965), first appearing in

Now that it has become evident that Late Repin (i.e. Yamnaya/Afanasevo) ancestry was associated with the migration of R1b-L23-rich Late Proto-Indo-Europeans from the steppe in the second half of the the 4th millennium BC, there’s still the question of how R1a-rich Uralic speakers of Corded Ware ancestry expanded , and how they spread their languages throughout North Eurasia.
Modern North Eurasians

First look of an accepted manuscript (behind paywall), Genome-wide sequence analyses of ethnic populations across Russia, by Zhernakova et al. Genomics (2019).
There remain ongoing discussions about the origins of the ethnic Russian population. The ancestors of ethnic Russians were among the Slavic tribes that separated from the early Indo-European Group, which included ancestors of modern Slavic, Germanic and Baltic speakers, who appeared in the northeastern part of Europe ca. 1,500 years ago. Slavs were found in the central part of Eastern Europe, where they came in direct contact with (and likely assimilation of) the populations speaking

The Nightmare Week of “N1c=Uralic” proponents (see here) continues, now with preprint Y-chromosome haplogroups from Hun, Avar and conquering Hungarian period nomadic people of the Carpathian Basin, by Neparaczki et al. bioRxiv (2019).
Hun, Avar and conquering Hungarian nomadic groups arrived into the Carpathian Basin from the Eurasian Steppes and significantly influenced its political and ethnical landscape. In order to shed light on the genetic affinity of above groups we have determined Y chromosomal haplogroups and autosomal loci, from 49 individuals, supposed to represent military leaders. Haplogroups from the Hun-age are consistent with Xiongnu ancestry of European
