This project aims to use genealogies from Orkneyinga saga to map out the family relationships between individuals from Orkney, Norway, Iceland, Scotland, and other areas of the Viking diaspora during the Viking Age and the Late Norse period. By doing this, it will establish the extent to which the aristocracies of Scandinavia and Scotland were interconnected. Furthermore, it will show the types of family relationships which maintained the interconnectivity of the Viking diaspora. By cross-referencing genealogical data from the sagas with documentary, archaeological, and place name evidence, this study will provide a detailed picture of this Norse-Scottish borderland. In addition, it will consider how the oral traditions which contributed to Orkneyinga saga flowed through the family networks of the Orkney earldom.
