Genetic research at a fivefold children's burial from medieval Berlin

Abstract Berlin originated from the two twin cities Berlin and Colln, which both were founded at the beginning of the 13th century. However the real date of their foundation as well as the origin of the first settlers is still unknown. On the Berlin site the historic city center is still visible in the Nikolaiviertel, but the medieval origin of Colln disappeared almost completely. In 2007 a large scale excavation, which comprised an area of about 1700m 2 of the historical center of the St. Peters church, recovers the remains of Colln's first citizens and span a period of 500 years of medieval population. Here we present the first genetic analysis of a fivefold children's burial from excavations in Berlin. The genetic data unveiled next to ancestry and eye color data also the kinship and the gender of the five individuals. Together with the archeological context the new gained information help to shed more light on the possible reasons for this burial.
