IslendingabokThe Icelandic population is very small and all Icelanders are related. But yet, it is big enough so everyone doesn’t know one another. This means that each and every Icelander that is in a relationship, is dating a relative. In most cases those relations are distant. But not always. But how can they know?


We all derive from the same family tree. An online registry, Íslendingabók  (‘The Book of Icelanders’) holds information about the families of about 720,000 individuals who were born in Iceland at some point in time. Today, the population in Iceland is just about 320,000. The database can be found on and everyone registered in the database has free access to it.

Everyone is related to Bjork

Being related to everyone has its merits. For example everyone in Iceland is related to Björk and every other Icelandic celebrity and politician you could find or think of.
Am I sleeping with or dating my cousin?

“Am I sleeping with or dating my cousin?” an Icelander might ask. The answer is: Of course you are, but how closely exactly are you related?

The answer to that can be found in the online database, but people might not always have the opportunity to look that up when they are for example out partying.

But now there is a solution.

“Bump the app before you bump in bed”

Three engineers made an app for the ‘Íslendingabók’ database. People can now easily, and on the go, look up how they are related to other Icelanders. And a precious feature, using the bump technology, allows people that meet to just bump their phones together, to instantly see if they are too related to take things any further. The engineers’ slogan for this feature was: “Bump the app before you bump in bed”.
