In Iceland, tracing one’s family roots is more than a pastime, it is a tradition interwoven with the country’s history. The Íslendingabók, or ‘book of Icelanders’, stands as a remarkable testament to this passion for genealogy, providing an online database that seeks to chart the ancestry of every Icelander for whom records exist.
From oral sagas to digital records
Interest in genealogy among Icelanders stretches back centuries, rooted in the earliest political and social structures of the island’s medieval society. Knowledge about family ties appears in old texts, sagas, and official documents, with this legacy kept alive through generations. Árni Fróði, known as Ari the Wise, authored the original Íslendingabók in the twelfth century to chronicle early Icelandic history, a title now carried by this modern genealogical effort.
The idea of collecting Icelandic genealogical data in a structured way took shape in the late 20th century, when Friðrik Skúlason began developing software to catalogue family histories. His initiative gained new momentum in 1997 through collaboration with deCODE genetics, whose scientific research relied on broad population data. Their combined efforts produced a system unlike any other: a genealogy database with national scope.
Creating connections across centuries
Today, Íslendingabók encompasses details on over one million individuals, more than half of all people who have lived in Iceland since settlement began in the ninth century. The database holds near-complete records for those born in the twentieth and twenty-first centuries and covers ninety-five percent of people born after 1700. Each entry includes information such as birth and death dates, family members, and places of origin.
Access is limited to Icelandic residents who possess a kennitala (national ID number), ensuring privacy and relevance. Registered users can explore their entire lineage and see connections among extended relations, with daily usage reaching into the thousands. The database also allows tracing links to anyone alive or deceased, as long as they are listed.
Compiling Íslendingabók has required more than 160 years of combined effort, drawing on sources from census records and church books to personal contributions. Community engagement is high; over 50,000 corrections and additions have come directly from users.
This vast genealogy web has become part of daily conversation and popular culture in Iceland. Many families, friends, and even colleagues have used the resource to uncover kinship ties during social events. The launch of the Íslendingabók app, which emerged from a University of Iceland competition, demonstrated the country’s enthusiasm as well as international curiosity.
As with any large project handling sensitive data, Íslendingabók has faced some criticism. Controversies over privacy and legal disputes with publishers have arisen, but the core database remains widely used and trusted. For Icelanders, the digital Íslendingabók is both a mirror of their past and a living part of modern identity.
