Overview
N-FGC27591 is a downstream branch of N-Y13874, one of the central Z1941-related Finnic paternal lineages. FGC27591 emerged during a period of increasing social complexity in early medieval Finland and Karelia, when permanent villages and fortified sites began to take shape. Its phylogenetic profile shows a mixture of narrow branches and stable sibling clusters, characteristic of small but persistent medieval founder groups. This clade represents a refined layer of the Y13874 diversification, capturing microstructure within Finnic populations along the eastern shore of the Baltic.
Geographic distribution
Carriers of N-FGC27591 are mainly found in eastern and central Finland, with notable presence in North Karelia, Savo and parts of the Karelian isthmus. The branch's distribution reflects historic settlement routes linking the Saimaa basin with Karelia. Minor frequencies appear in Estonia and northwest Russia, consistent with medieval population interactions.
Ancient DNA
- Upstream Z1941 and Y13874 lineages are confirmed in Iron Age and medieval Finnic populations, indicating long-term continuity.
- FGC27591's formation age places it squarely in the period of Finnish inland expansion and cultural consolidation.
- The branch structure suggests multiple patrilines coexisting rather than collapsing into a single dominant founder line.
Phylogeny & subclades
In YFull phylogenies, FGC27591 is shown as one of several downstream subclades of Y13874, with multiple identifiable branches. Its placement highlights the complexity of Finnic paternal diversification and the presence of regionally stable groups rather than singular rapid expansions.
- N-FGC27591*
- Several private and semi-private Finnish downstream branches
Notes & context
N-FGC27591 is important for fine-resolution Finnish genealogical interpretation, especially among families with medieval eastern Finnish roots.
