Overview

N-BY14019 is a downstream branch of N-Y17252 and part of the early VL62 → Y9022 Finnish ancestral layer. It reflects a paternal line that formed slightly before the main Z1939-dominated medieval expansions. As a result, BY14019 preserves elements of the proto-Finnic paternal landscape during the transition from late Iron Age to early medieval social organization. Its moderate internal diversity suggests stable lineage continuity rather than extreme founder effects.

Geographic distribution

BY14019 carriers occur across eastern Finland, Karelia, and scattered locations in northwest Russia. The clade appears in Savo–Karelia lake districts and along the Ladoga–White Sea interaction zone. This spread aligns with the known proto-Finnic settlement spheres that existed prior to later medieval population consolidations.

Ancient DNA

  • VL62-based ancestry is found in Iron Age Finnic individuals, supporting BY14019’s placement in an early paternal layer.
  • The divergence timing corresponds to population structuring in northeast Europe tied to early Finnic cultural development.
  • Branch diversity implies persistence in multiple local communities over long durations.

Phylogeny & subclades

In YFull, BY14019 sits under Y17252 with several downstream mutation-defined lines. Its position marks a branch that remained separate from the much larger downstream Z1939 → Y7308/Y7310 clusters.

  • N-BY14019*
  • Minor derived Finnish–Karelian branches

Notes & context

BY14019 is crucial for mapping the early Y9022 landscape and helps prevent overemphasis on the later, more populous macroclusters.
