I’m jealous! One country has everyone’s family tree, complete with original source citations, online and available for all the country’s citizens to see. In fact, there is even an Android app available to show each Icelandic citizen his or her genealogy, in most cases back to 874 AD.
Everyone in Iceland is related. Every member of the 300,000 population derives from the same family tree, according to genealogy website islendingabok.is.
The islendingabok.is web site hosts the online registry Íslendingabók (“The Book of Icelanders”). In it one can find information about the families of about 720,000 individuals who were born in Iceland at some point in time. Anyone who is registered in the database has free access to it.
Íslendingabók is the product of a cooperation between Icelandic company, deCODE Genetics, and Fridrik Skúlason, who first began registering genealogy information in 1988 into a program called Espólín. In 1997 Skúlason and deCODE began cooperating on registrations for genealogy research, and Íslendigabók was born.
Íslendingabók claims to be the only genealogy database in the world that covers a whole nation. More than 95 percent of all Icelanders born since 1703, when the first national census was taken, are registered in the database, along with half of all Icelanders who have lived on the island from the settlement in 874 until 1703.
