The Estonia_EarlyViking dataset comprises 34 genome-scale samples from Saaremaa (Salme), dated 649–949 CE. Y-chromosome lineages show a predominance of haplogroup I (16 individuals), with substantial representations of R (7) and N (7), and smaller counts annotated as I1a (2) and I1 (2). Mitochondrial diversity is notable: H lineages are common (12), with J (4), H16 (4), T (4) and U (3) also present. This paternal and maternal mix indicates a community reflecting northern European ancestry alongside influences that are frequent in northeastern Baltic and Uralic-associated populations.
Haplogroup I (including I1/I1a) is frequently associated with long-term presence in northwest Europe and Scandinavia; its dominance here supports archaeological ties to Scandinavian-style seafaring cultures. Haplogroup R (a broad clade common across Europe) reinforces western and central European affinities. Haplogroup N is frequently observed in northeastern Europe and is often linked in population studies to Uralic-speaking groups; its presence among Salme individuals suggests gene flow or contact with eastern Baltic or inland northeastern populations.
Autosomal signatures described by researchers for comparable Baltic Viking-age samples often show mixed Scandinavian, Baltic, and northeastern inputs; however, without broader regional sampling it is premature to assert precise proportions. Because this dataset is concentrated at Salme (n=34), conclusions about all of Early Viking Age Estonia must remain cautious: these genomes illuminate local dynamics and contacts but further geographically wider sampling is required to map population structure across Estonia.
