Legowo Heritage: Voices from Łęgowo

The assemblage from Łęgowo (Greater Poland Province, Wągrowiec) sits at an archaeological crossroads. Excavations at the site have produced human remains dated by radiocarbon to roughly 1000–1200 CE, placing these individuals in the High Middle Ages. Archaeological data indicates that the locale was occupied during a period of dynamic cultural interaction in Central Europe: settlement shifts, trade along river corridors, and reuse of older ritual landscapes. The site label "Legowo" echoes an earlier Iron Age lithic and settlement tradition in the region (often referred to in literature as the Legowo cultural horizon), but in this case the recovered burials are medieval in date. This suggests either continuity of place use across millennia or the reoccupation of a landscape with deep symbolic resonance.

Limited evidence suggests local agrarian lifeways blended with wider regional influences: pottery fragments, ironwork, and burial orientation reflect common medieval practices in Poland while also showing idiosyncratic local traits. Because only four genetic samples are available, interpretations of population origin or migration must remain tentative. Archaeological context, however, anchors the genetic data to a specific time and place, allowing us to explore how these individuals connected to both earlier local traditions and broader medieval networks in Central Europe.

Ancient DNA from four individuals at Łęgowo provides a narrow but informative genetic snapshot. Y-chromosome profiles show three individuals assigned to haplogroup R and one to haplogroup L. Haplogroup R is common across Europe in the medieval period (encompassing sublineages often associated with R1a and R1b), so its dominance here aligns with broader regional patterns. The single L Y-chromosome is noteworthy: haplogroup L is uncommon in medieval Central Europe and today is found at higher frequencies in South Asia and parts of Southwest Asia. Its presence at Łęgowo could reflect individual mobility, a recent migrant ancestor, or a cryptic local lineage; with only one occurrence among four samples, this remains speculative and warrants further sampling.

Mitochondrial DNA is dominated by haplogroup H (two individuals, including an H1c sublineage) with one T2b. Haplogroup H is the most frequent maternal lineage in Europe since the Neolithic and its presence here is consistent with long-term maternal continuity. T2b also occurs widely in Europe and the Near East and can reflect Neolithic and later population movements. Taken together, the uniparental markers suggest a primarily European genetic background with at least one unusual paternal lineage that highlights the complexity of medieval mobility.

Importantly, conclusions are preliminary: four samples are below standard thresholds for population-wide inference (<10 samples). Future targeted sampling and genome-wide data would clarify ancestry proportions, potential kin relationships among the burials, and whether the Y-L signal recurs in the region.
