We investigated ancestry, kinship, and health in individuals from three cemeteries in Finland: Tampere Vilusenharju and Pälkäne Ristiänmäki (11th-12th centuries) and Rauniokirkko (13th-19th century). The oldest burials provide insights into Finland's medieval population, otherwise poorly known due to poor bone preservation. Using ancient genomic data, contemporary Finnish Biobank data, and identity-by-descent (IBD) analyses, we identified strong regional continuity between the medieval and modern Finnish populations and evidence for mobility within Finland and between Finland and Scandinavia. Kinship analysis identified a sibling relationship between individuals buried 30 km apart and indicated a shared genetic background for individuals from the three cemeteries. However, individuals buried in physical proximity at Rauniokirkko were not closely related, suggesting that social ties, not family relations, shaped burial practices. The pattern may reflect emerging Christian mortuary norms and community-based burial organization. Pathogen screening revealed potential and infections, shedding light on disease burden in medieval Finland.
我们研究了来自芬兰三个墓地的个体的血统、亲属关系和健康状况：坦佩雷的维卢森哈茹墓地和帕尔卡内的里斯蒂安迈基墓地（11至12世纪）以及劳尼奥教堂墓地（13至19世纪）。最古老的墓葬为了解芬兰中世纪人口提供了线索，否则由于骨骼保存不佳，这方面情况鲜为人知。利用古代基因组数据、当代芬兰生物样本库数据以及同源性分析，我们发现中世纪和现代芬兰人口之间存在很强的区域连续性，并且有证据表明芬兰境内以及芬兰与斯堪的纳维亚之间存在人口流动。亲属关系分析确定了相距30公里埋葬的个体之间存在兄弟姐妹关系，并表明来自三个墓地的个体具有共同的遗传背景。然而，在劳尼奥教堂墓地相邻埋葬的个体并非近亲，这表明塑造埋葬习俗的是社会关系而非家庭关系。这种模式可能反映了新兴的基督教丧葬规范和基于社区的埋葬组织。病原体筛查揭示了潜在的[此处原文缺失具体病原体信息]和[此处原文缺失具体病原体信息]感染，为了解中世纪芬兰的疾病负担提供了线索。
