I previously wrote an article about my fascination with the ‘science of husbandry on a human scale‘.
My interest in this subject was piqued by my own Acadian ancestry and the Acadians’ practice of ‘managing’ biological relationships through the church in order to safeguard against close relatives marrying and having children. This has been a necessity through the centuries as a result of people living in small communities that were widespread. The modes of transportation were primitive and substantially increased the possibility of relationships and marriages within family lines. The Acadians recognized these relationships as existing within levels of ‘consanguinity’ or ‘closeness of biological relationship’.
The culture that shares the this Acadian practice to the greatest degree is that of Iceland. They have taken their management of these relationships to a different and greater level through consultation with the Íslendingabók database, a national database of ancestral lines and family trees reaching back several centuries, with their incest prevention app.
Students of the University of Iceland in Reykjavík won a contest for apps run by the Íslendingabók database. With their Android incest prevention app called ‘Sifjaspellsspillir’ or ‘Incest Spoiler’, two people with the app just tap their phones and if they share a grandparent, they will receive an alert. The creators are hoping to make it able to alert regarding common great grandparents in the future.
