Abstract format: Poster

Southwest Finland has rich Late Iron Age archaeological records that show diverse cultural and trade networks. Ancient DNA analyses
from human remains, however, have remained scarce due to the acidic Finnish soil that leads to a rapid decay of bone material.
Two large inhumation burial grounds from the Crusade Period (1050–1150 CE) in Southwest Finland, Raisio Kansakoulunmäki and
Masku Humikkala, represent the transition period towards Christianity. The favourable skeletal preservation on these sites offers a
possibility to analyse the genetic structure of the Iron Age communities behind the burial context. Combining this genetic data to
other periodically and regionally close individuals enables an in-depth examination of the population history of Late Iron Age Southwest Finland.
In this archaeogenetic study we investigate the genetic composition of altogether 29 individuals, 14 from Kansakoulunmäki and
15 from Humikkala. A closer analysis of kinship patterns and genetic ancestry provides comprehensive information of the Late
Iron Age communities, such as family relations and patrilocality. All samples in this study have been processed in dedicated cleanroom facilities.
Ancient DNA libraries have been enriched for ancestry-informative markers in human DNA, and the data retrieved
with high-throughput next-generation sequencing. The preliminary results for seven Raisio Kansakoulunmäki individuals indicate a
genetic continuity with contemporary Finnish populations. Our current analyses intend to provide a detailed view of the ancestry
components, kinship and genetic affinities for all successful samples.
